We look forward to helping you save fuel. The following manual will guide you through the installation procedure. You can expect the procedure to take approximately 5 man hours. However, experienced installers can reduce the install time to approximately 4 man hours. Before getting started, take a look at the “What You Will Need” section on the next page to make sure you have the necessary tools and equipment. If you have questions or if we may be of any assistance, please give us a call: TOLL FREE INSTALLATION HELP LINE: 866-464-9464 (8AM - 5PM PST) The illustration below provides an example of a typical mounting position for the AeroFlex Maxx on a 53’ trailer. The exact fit on the trailer and ground clearance can vary due to different trailer makes, models and configurations. This manual will enable you to customize the fit for different trailers. What You Will Need 3 The following tools are needed to install the Freight Wing AeroFlex Maxx Fairing: 1. Drill, preferably high speed. 2. Impact wrench, preferably light duty 3. 7/16” & 1/2" deep sockets 4. 7/16” & 1/2" wrenches 5. 5/16" drill bits (high speed bit for drilling steel, we recommend Fastenal # 3199336) 6. Clamps - ideally at least sixteen 3” C clamps (other sizes of clamps or vice grips will also work) 7. A string chalk line 8. Safety glasses 9. 2" metal separation tape (used when top aluminum channel is mounted to steel cross members for corrosion protection. Clear packing tape is sufficient) 10. 5” and 2.5” diameter hole saws, and/or a jigsaw. If installing on a refrigerated trailer: 11. A square ruler You may also want: 12. Degreaser Cleaner. D-Limonene or Dupont 381 are the two best cleaners to use. You may also use Spray Nine, Purple Power, Lysol 3/1, or Pine-Sol 100% concentration. Danger: Follow all manufacturer instructions in use of products above . Do not use any acid based products or brake cleaner. 13.

(This step is completed in kitted units) Slide the support rod (68-50182-00) into the saddle (68-50140-00) as shown below. Note that the saddle extends away from the body of the rod. Insert 5/16 x 1.6 custom hex bolt (10475-03774) and firmly tighten the 5/16-18 YZ Nylock flanged nut (01900515) until it hits the shoulder. Repeat for opposite end of rod. Repeat the process for all 20 rods in each unit. 1b. On one end of the rod, assemble the saddle clamp bottom plates and top plates (68-50183- 00 and 68-50184-00) with two 1/4-20 x 1.25 tap bolts (71170) and 1/4-20 YZ Nylock nuts (01900458) as shown below. Half (10) of the clamps should be oriented to the left side of the saddle mount as shown below in the illustration on the left, and half (10) should be oriented to the right side as show below in the illustration on the right. When placed on the trailer, optimal clamp placement on one side of the trailer will mirror the other side, so that 10 of each clamp orientation will be used. 1c. When mounting the faring on trailers with steel cross members (typically dry vans), apply a “barrier” tape across the top of the L-channels to separate the metals, thus preventing corrosion. This step is not necessary for trailers with aluminum cross members (typically reefers). Any corrosion barrier tape will work for this step, and standard 2” wide clear packing tape (polypropylene tape) is an effective option (preferably heavy duty packing tape that is thicker than standard packing tape). 8 Step 2: Determine the Starting Rear Position of the AeroFlex Fairing Properly positioning the AeroFlex Maxx fairing on the trailer is important for aerodynamic effectiveness and unobstructed operation of the trailer. Because trailers have different axle and slider configurations, the position of the fairing can vary. In general, the placement of the rearward edge of the rear panel determines the fairings overall position. This rearward edge should be as close to the tires as possible but must leave enough room for sliding tandems to move into their most forward position with a minimum of 3” of clearance to the tires. It should also be flush with the outer trailer wall. From that rear position, the fairing is then mounted in a straight line, though angled, so that the forward tip is just outside (2 inches) the landing gear legs or any obstructions created by the landing gear (wing plates, leg supports, etc). Caution: Improper fairing positioning could interfere in proper operation of the trailer. 2a. Identify the trailer cross member best suited to start mounting the rearward corner of the fairing. First, slide the axles to the most forward pin position (if necessary). (After this is completed, sliding them to the rearward most position will allow better access under the trailer during install) Make a mark on the trailer side rail directly above the front edge of the forward tire. From this mark, measure a minimum of 3” along the side rail, towards the front of the trailer as illustrated below. Use the closest cross member in front of this point to mount the rearward corner of the fairing. Typically, this will be the cross member directly forward of the welded stop or bar in the slider rail.
