For 2015 it features an all-new cab and interior, along with greater connectivity via OnStar with 4G LTE and a standard built-in Wi-Fi hotspot, building on its reputation for dependability and top-rated performance with more customer- focused features. OnStar with 4G LTE (fall 2014 availability) provides a mobile hub for drivers and passengers to stay connected. The hotspot is on whenever the car is on and comes with a three-month/three-gigabyte data trial. The 2015 Sierra 3500HD Chassis Cab models are based on the redesigned heavy-duty pickups of the same name. Highlights include: x All-new exterior styling with enhanced cooling airflow, which enables the standard 6.0-liter Vortec V-8 and available 6.6-liter Duramax turbo diesel to better maintain full power, even under heavy loads and high ambient temperatures x All-new interior that provides increased space and comfort, with extensive storage space tailored to the way customers use trucks x Integrated cruise control, auto grade braking and diesel exhaust braking (on diesel models) that help make tough towing easier. Sierra 3500HD Chassis Cab is available in regular cab and crew cab body styles, with Work Truck and SLE trims. All models are offered in 2WD or 4WD – and feature dual rear wheels. The Duramax diesel engine, with 397 horsepower (296 kW) and 765 lb-ft of torque (1,037 Nm), is available. Regular cab models are available in 137.5-inch and 162-inch wheelbase lengths, while the crew cab rides on a 171.5-inch wheelbase. The cab-to-axle (CA) length is 60 inches for the regular cab/137.5-inch wheelbase and crew cab models. The CA is 84 inches for the regular cab/162-inch wheelbase configuration. Additional lineup features include: x Fully-boxed front frame with reinforced C-channel rear frame x Standard 63.5-gallon (240 liters) fuel capacity (23.5-gallon/89-liter front tank and 40-gallon/151-liter rear tank) x Smart exhaust brake (with Duramax engine) feature that provides greater control on grades and reduced brake pad wear x Standard frontal air bags x Standard StabiliTrak stability control system x Seventeen-inch wheels x Four-wheel disc brakes with anti-lock x Available power take-off x Available skid plate package x Available snow plow prep package x Available upfitter switches. Sierra 3500HD Chassis Cab is built to haul, with capabilities for each model reaching a maximum GVWR rating of 13,200 pounds, with payload ratings ranging from 5,702 pounds (crew cab 4WD) to 7,490 pounds (regular cab 2WD with the 137.5-inch wheelbase). A 6.0L gas V-8/six-speed automatic powertrain is standard in all models. A Duramax 6.6L turbo-diesel is available, paired with the Allison 1000 six-speed automatic transmission. Exterior highlights The new truck cab is stronger, as well, with nearly two-thirds of the cab structure made from high-strength steel for a confident feel and improved safety. The rear doors on crew-cab models are larger, enabling easier entry and exit for rear-seat passengers, and revised seats create approximately two inches more rear legroom. Structural reinforcements and other components also help stiffen the body, contributing to confident, quiet performance on the highway, with noticeably reduced vibrations on rough surfaces. They include an enhanced instrument panel support beam, which spans the width of the cab’s interior under the dashboard, features a new beam-to-floor brace that is four times stronger than before. It’s used with stronger instrument panel mounting brackets and a thicker tubular steering column jacket to enhance the steering column’s stiffness, reducing vibration that could otherwise be felt in the steering wheel. New inlaid doors, which fit into body sides rather than wrapping over the roof, combine with new triple door seals to reduce wind noise and turbulence, helping quiet the cab. The front of the truck is also carefully sealed to provide efficient cooling with minimal aerodynamic drag, including a new grille opening reinforcement mounted over the radiator support and the frame. It is a primary contributor of the sealing process, enabling tailored alignment of the hood, fenders, bumper, grille and headlamps, for a tight fit between parts that enhances airflow through and around the truck. Additional exterior features include: x Folding camper-style mirrors are standard; heated/power-adjustable features available x Seventeen-inch, eight-lug steel wheels are standard; forged polished aluminum wheels are available on LT crew cab x Dual halogen headlamps x Smoked amber roof lamps. Regular-production exterior colors: Stealth Gray Metallic, Quicksilver Metallic, Summit White, Onyx Black, Sonoma Red Metallic, Fire Red, Cobalt Blue Metallic, Bronze Alloy Metallic and Iridium Metallic. Special paint exterior colors: Yellow, Wheatland Yellow, Tangier Orange, Blue Metallic, Dark Toreador Red, Indigo Blue, Light Autumnwood Metallic and Pewter. Interior features Inside, the 2015 Sierra 3500HD Chassis Cab receives the same updates as the 2015 Sierra HD pickups, including an upright instrument panel that puts important controls within easy reach, a six-gauge instrument cluster with driver information center, and multiple storage options tailored specifically to the needs of truck customers. Controls are functional, logically placed and easy to operate with work gloves on. For example, the available Integrated Trailer Brake Controller is mounted high on the left side of the instrument panel, where it can be easily adjusted, and it displays Gain on the Driver Information Center in the instrument cluster. Storage spaces and compartments include an upper and a lower glove box, as well as a “mini” glove box beneath the center stack of the instrument panel on models with a bench seat; and the rear-console storage area on crew cab models is designed to hold a bag and be used as a refuse bin, which helps keep the truck cleaner on long drives. The front door panels have integrated map pockets, as well as space for drink bottles. The front of the panels can each hold a pair of 1.5-liter bottles, while the rear of the panel has room for a typical 20-ounce bottle. The standard front seat is a 40/20/40-split bench with a fold-down center armrest that features covered storage, three cup holders, two USB ports and two 12-volt power points. Additional interior features include: x Reclining 40/20/20-split bench seat is standard x Rear 60/40-split fold-up bench seat (crew cab) x Leather seating surfaces are available x Air conditioning is standard x Electric assist heater incorporated in Duramax-equipped models to help warm up the cab more quickly x Cruise control and tilt steering are standard x Power-adjustable pedals are available x Power-operated rear sliding window is available on crew cab models x Interior color/trim combinations: Jet Black, Jet Black/Dark Ash and Cocoa/Dune. Onstar with 4G LTE Technology is essential for those who work out of their truck, and the new OnStar with 4G LTE and standard built-in Wi-Fi hotspot provides a mobile hub for drivers and passengers to stay connected. The hotspot is on whenever the vehicle is on and comes with a three-month/three gigabyte data trial. 4G LTE is the most current and fastest mobile data network – 10 times faster than 3G and 100 times faster than the previous generation of OnStar hardware. And with OnStar, it also offers stronger, broader coverage than smartphones on the same network and it’s easy to use: If the vehicle is on, the connection is on. Powertrains that perform Under the hood of the Sierra 3500HD, a Vortec 6.0L gas V-8 with variable valve timing is paired with the Hydra-Matic 6L90 six-speed automatic transmission as the standard powertrain offering. This combination delivers excellent performance and efficiency, with an emphasis on low-rpm performance. It is rated at 322 horsepower (268 kW) and 380 lb-ft of torque (515 Nm). The Duramax 6.6L turbo-diesel and Allison 1000 six-speed automatic transmission powertrain combination is available on all 3500HD models. Highlights of the Duramax diesel include: x 397 horsepower (296 kW) at 3,000 rpm x 765 lb-ft of torque (1,037 Nm) at 1,600 rpm x High-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions x Exhaust brake system that enables controlled vehicle slowdown on downhill grades with minimal brake actuation x Selective catalytic reduction after-treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance – with a range of about 5,000 miles (8,000 km) between DEF refills x Combustion and after-treatment have been optimized to provide about 700 miles (1,125 km) between diesel particulate filter regenerations – a 75-percent improvement over the previous system and significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel x B20 biodiesel capability for an alternative fueling option.

All Rights Reserved. 03/07 1 Key FAQs What is roll stability? Roll stability counteracts the tendency of a vehicle, or vehicle combination, to tip over while changing direction (typically while turning). The lateral (side) acceleration creates a force at the center of gravity (CG), “pushing” the truck/tractor-trailer horizontally. The friction between the tires and the road opposes that force. If the lateral force is high enough, one side of the vehicle may begin to lift off the ground potentially causing the vehicle to roll over. Factors influencing the sensitivity of a vehicle to lateral forces include: the load CG height, load offset, road adhesion, suspension stiffness, frame stiffness and track width of vehicle. What is yaw stability? Yaw stability counteracts the tendency of a vehicle to spin about its vertical axis. During operation, if the friction between the road surface and the tractor’s tires is not sufficient to oppose lateral (side) forces, one or more of the tires can slide, causing the truck/tractor to spin.

  • Study of the Torsion Bar Passive Suspension System
    Minia Journal of Engineering & Technology (MJET), Vol. 37, No. 1. January 2018 STUDY OF THE TORSION BAR PASSIVE SUSPENSION SYSTEM Mohamed Khairy1, S. Allam1 and M. Rabie2 1Automotive Technology Department, Faculty of Industrial Education, Helwan University. 2Automotive and Tractor Dept., College of Engineering, Minia University. E-mail of corresponding author: [email protected]. Abstract A torsion bar passive suspension is a general term for any vehicle suspension that uses a torsion bar as its main weight bearing spring. The main advantages of a torsion bar passive suspension system are durability, easy adjustability of ride height, and small profile along the width of the vehicle. It takes up less of the vehicle's interior volume than coil springs. The purpose of this study is to investigate the effect of the ride height of a vehicle which adjusted by the torsion bar on the vehicle body vibration in torsion bar passive suspension system. In this work the study, a front suspension of double-wishbone type suspension with upper torsion bar is assigned as quarter car model and is considered for the performance index study. Tire speed, sprung mass weight and presence of the hump are taken into consideration as the operation parameters. The results show the change of the torsion bar bolt position has sufficient effect on the sprung mass acceleration Keywords: vehicle suspension systems, torsion bar, ride comfort. 1. Introduction One of the major subsystems in a modern passenger car is the suspension system. The suspension system of a road vehicle refers to the assembly between the sprung mass and the unsprung mass.

  • Trim Height Inspection
    3/11/2016 Document ID: 745583 2004 C adillac Escalade - AWD [1gyek63n34r121918] | Avalanche, Escalade, Suburban, Tahoe, Yukon VIN C /K Service Manual | Suspension | Wheel Alignment | Specifications | Document ID: 745583 Trim Height Inspection Trim Height Measurements Trim height is a predetermined measurement relating to vehicle ride height. Incorrect trim heights can cause bottoming out over bumps, damage to the suspension components and symptoms similar to wheel alignment problems. Check the trim heights when diagnosing suspension concerns and before checking the wheel alignment. Perform the following before measuring the trim heights: Make sure the vehicle is on a level surface, such as an alignment rack. Remove the alignment rack floating pins. Set the tire pressures to the pressure shown on the certification label. Refer to Vehicle Certification Label in General Information. Check the fuel level. Add additional weight if necessary to simulate a full tank. To ensure proper weight distribution make sure the rear storage compartment is empty. Close the doors and hood. Z Height Measurement Important: K models only the Z height must be adjusted before the alignment. The Z height dimension measurement determines the proper ride height for the front end of the vehicle. Vehicles equipped with torsion bars use a adjusting arm in order to adjust the Z height dimension. Vehicles without torsion bars have no adjustment and could require replacement of suspension components. Important: All dimensions are measured vertical to ground. Cross vehicle Z heights should be within 12 mm (0.47 in) to be considered correct. 1. Place hand on the front bumper and jounce the front of the vehicle.
