Before you begin:

Do not carry more than 1000 pounds (454Kg) for leg mount or 750 pounds (340Kg) for cap mount of combined cargo and accessories on ProRac crossbars. Distribute loads evenly across both crossbar. ProRac cannot warranty loads that exceed this limit. Remove all components from the shipping carton and read the instructions thoroughly to familiarize yourself with the assembly sequence. Gather the following tools used to assemble and install the rack. 9/16” Socket and open end wrench 3/8” dia drill bit and drill Marker Tape measure Tape

Step 1 – Locate legs on truck bed Locate on the truck bed where the front and rear legs will be positioned. The ideal positions for the legs are as far forward for the front legs and as far rearward for the back leg. You will need to have open access underneath the top of the bed surface for mounting the legs to the bed. Check for obstructions in mounting the legs to the truck bed such as stake pocket holes or limited access to the underside of the top surface of the bed. Check for function of tailgate or interference with the cab of the truck. Adjust as needed. The spacing between the centers of the bolt holes is 4-1/2”. Place tape over the desired positions. Place a leg on top of the tape and position the leg to the desired location on the top surface. For best results, use a tape measure so each legs is positioned equally with the other side.

Using a marker, mark the outline of the leg and the center of the two mounting holes onto the tape. Repeat for all legs

Cap Plate Mount Measure from driver side to passenger side inside edges of the bed rail. See illustration below. Front truck leg or cap mount span = _____________________ Rear truck leg or cap mount span = _____________________ Measure the distance between the marked inside edges of the legs front to back and record the value below. Inside span between front and rear legs = _____________

From the measurements above Front cap bed mount span +12” = ___________ Rear cap bed mount span +12” = ___________

Step 3 Crossbar assembly Crossbar width fit Because truck beds widths can taper front to back, each crossbar will be set specifically to match where it is mounted on the bed. The crossbar width will be 5-1/4” shorter than the length measured. Using the measurements from step 2, Front Legs span ___________________ - 5-1/4” = _________________ Rear Legs span ____________________ - 5-1/4” = _________________ Slide the 1-3/4” inner crossbar tube into the 2” out crossbar tube as shown until they measure the length from above. Temporarily secure the two crossbars together by wrapping tape around the end of the 2” outer crossbar and 1-3/4” inner crossbar.

Using the 2” tube bolt holes as guides; mark the center of the holes using a center punch. Drill the holes marked with a 3/8” drill bit on both sides. Remove tape that was temporarily holding the two crossbars together. Align the bolt holes of both tubes. Apply a small bead of silicone around the bolt holes on the larger tube. Insert the 3/8”-16 x 2-3/4” bolt with a flat washer through the crossbar. Secure the bolt with a flat washer and 3/8”-16 nylon insert lock nut. Repeat for other bolt hole. Place the end caps on the ends of the crossbar. Apply silicone to the gap between the inner and outer crossbar to seal out water and reduce wind noise. Repeat step for other crossbar.

Step 4 Crossbar to leg assembly Note: Rail pass through tube on leg is not shown for exploded view clarity. You may mount to either the front side or rear side of the legs. Orientate the 1-3/4” tube as shown (note the holes are not centered on this end of the crossbar) Starting with the bottom hole first, insert the 3/8”-16 x 4-1/2” bolt with a flat washer through the leg and 1-3/4” square crossbar. Secure the bolt with a flat washer and 3/8”-16 nylon insert lock nut. Note the spacing between the washer fit is tight, it maybe necessary to adjust the washer centering so they will both fit flush on the legs and crossbars. Repeat for other bolt hole. Lightly tighten the hardware. Insert the 2” square end cap into the top of the leg.

Step 4 (continued) Crossbar to leg assembly Note: Rail pass through tube on leg is not shown for exploded view clarity. Orientate the 2” tube as shown (note the holes are not centered on this end of the crossbar) Starting with the bottom hole first, insert the 3/8”-16 x 5” bolt with a flat washer through the leg and 2” square crossbar. Note the spacing between the washer fit is tight, it maybe necessary to adjust the washer centering so they will both fit flush on the legs and crossbars. Secure the bolt with a flat washer and 3/8”-16 nylon insert lock nut. Repeat for other bolt hole. Insert the 2” square end cap into the top of the leg.

Lightly tighten the hardware.

Step 10 Front Leg to front rail Remove the tape from the front leg rail pass through tubes and adjust the front legs so they are perpendicular to the rails. Check that the legs to crossbar assembly is square and tighten the hardware, starting with the crossbar bolts and then proceeding to the legs. Locate the center of the holes on the front legs rail pass through tube marked holes and use a center punch Drill a 3/8” holes on one side and insert a 3/8” bolt through the leg and into the rail to hold the leg to rail assembly in place and continue to drill the other (3) holes. Secure with hardware and apply silicone to the flat washers. Tighten the leg hardware.

Repeat for other side. Seal the gap of the front rail and the rail pass through tubes with silicone. Check to make sure the crossbar is square to the upper portion of the legs. Adjust as needed and then tighten the hardware. Go around rack and check and tighten all hardware.

Removable rear cross bar option. The rear crossbar can be removed or pivot out of the way when loading tall upright cargo into the truck bed. Removal To remove the rear crossbar - unbolt the crossbar from the leg on both sides. NOTE: Always have the crossbar secured with all bolts on both ends when using the vehicle. Pivoting crossbar Note! This feature should only be used when a load is not carried on the crossbars. If a load is going to be carried on the crossbars, all four bolts must be used to secure the crossbar to the legs! To change the rack for pivoting the rear crossbar, remove the hardware holding the rear crossbar in place. On the end with the 1-3/4” inner crossbar, use a 4-1/2” bolt with flat washer and slide them through the upper hole of the leg. Place a flat washer on the 4-1/2” bolt and move it to so it contacts the leg. Place the crossbar onto the bolt and slide towards the leg. Secure the crossbar to the leg using a flat washer and nylon insert lock nut. Tighten the nut and bolt enough so the crossbar can be rotated around the bolt but not binding.

Place the crossbar onto the bolt and slide towards the leg. Secure the crossbar to the leg using a flat washer, split lock washer and wing nut. Tighten the wing nut enough to flatten the split lock washer.

NOTE: Always check so make sure the wing nut is tight before and during use. If the wing nut loosens, replace by removing the split lock washer and use a 3/8”-16 nylon insert lock nut. NOTE: Always have the crossbar secured on both ends when using the vehicle.
