1.Do not install mounting rails over plastic bed liners. Plastic bed liners must be cut out of the way to provide metal to metal
contact. Mounting rails may be installed on spray in liners.
2.Use only bolts, nuts, and washers supplied to install this kit. All bolts & nuts are Grade 5 unless otherwise specified.
3.These instructions are guidelines only, actual installation is the responsibility of the installer and the owner. Always measure
truck and trailer before installing hitch to be sure that there is clearance at the cab and at the bumper to allow for turns.
4.Lower and remove spare tire if extra room is needed. Remove inner plastic wheel well liner to allow access to frame.
5.Detach the electrical wire loom and brake lines from the inside driver side of the frame.
6.Place the rear mounting rail in the box of the truck, using your tape measure, center the rail between the weld seams on the
length of the truck box floor and the proper distance from the rear edge of the truck box as shown in Figure 2.
Note: It is critical that rail is centered side to side on the truck bed.
7. Mark and center punch the holes as shown in Figure 2 (Rows 1 & 2). Remove the rail and drill each position with a 1/8
drill bit.
8.Temporarily position the frame bracket on the outside of the frame and check that the 1/8 drilled holes align with the slots
of the frame bracket. Remove the frame bracket from the vehicle.
9.Enlarge the 1/8drilled holes to 9/16”.
10.Loosely install the frame brackets (front (1)(2) & rear (3)(4)) by attaching the bolts (6), conical washers (7). (See Figure 1)
11.Move rear mounting rail into position. Install the ½”-13 x 2” carriage bolts that are supplied with the rails with the block
spacer to be located in the corrugation between the box and the mounting rail or between the box and rear brackets (3) (4),
through the rail and rear brackets (3) (4). (Note the block spacer is to eliminate crushing bed corrugation.)Attach .25” x 1” x 3” block (5), 1/2” conical washers and ½” nut to the underside of the brackets per the illustrations and tighten snug to
keep the mounting rail from moving. (For Row 1)
12.The forward side of the rear rail’s holes (row 2) will fasten directly through the truck bed as shown in Figure 1 with the ½” conical washers and ½” nut fastening to the underside of the truck bed.
13.Place the unassembled 5th wheel saddles/slider/goose into the already installed mounting rail. Position the front mounting
rail with the saddles/slider/goose by inserting the tabs into the mounting rail and pushing the mounting rail tight towards the
other mounting rail. Ensure that the mounting rail is centered between the weld seams on the length of the truck box floor.
This will position the mounting rail in the correct location and ensure that the 5th wheel will have a snug fit to the truck.
NOTE: If more than one hitch product will be used with the rails then both should be used at the same time to align the
second rail. This will ensure that one product does not compromise the fit of the other.
14.Repeat steps 8 through 10.
15.Move the mounting rail into position. Install the ½”-13 x 2” carriage bolts with the block spacer to be located in the
corrugation between the box and the mounting rail or between the box and front brackets (1) (2). (Note the block spacer is
to eliminate crushing bed corrugation.) The rear end of the front brackets (Row 3) will be attached using the .25” x 1” x
3” block (5), ½” conical washers and ½” nut like described in step 8 and shown in Figure 1. Attach the forward side of the
front brackets (Row 4) with spacers, washers and nuts as per the illustrations and tighten snug to keep the mounting rail
from moving.
16.After fully installing the 50054 custom mounting brackets, tighten the fasteners in the following sequence. Note: Torque
all 1/2” hardware to 75 ft-lbs 102 (N*M) and all M12 hardware to 92 ft-lbs (125 N*M). First torque the mounting
rails to the frame brackets and then torque the frame brackets to the truck frame.
17.Reinstall electrical wire loom and brake lines. Replace inner plastic wheel well liner to body, if removed reinstall spare tire.

8.Temporarily position the frame bracket on the outside of the frame and check that the 1/8 drilled holes align with the slots
of the frame bracket. Remove the frame bracket from the vehicle.
9.Enlarge the 1/8 drilled holes to 1 1/8”.
10.Loosely install the frame brackets (front (1)(2) & rear (3)(4)) by attaching the bolts (6), conical washers (7). (See Figure 3)
11.Move rear mounting rail into position. Install the 5/8”-11 x 2.5” (5) carriage bolts that are supplied with the .657” x 1.271”
tube spacer along with the block spacer to be located in the corrugation between the box and the mounting rail or between
the box and rear brackets (3) (4), through the rail and rear brackets (3) (4). (Note the block spacer is to eliminate crushing bed corrugation.)Attach 5/8” conical washers and 5/8” nut to the underside of the brackets per the illustrations and tighten
snug to keep the mounting rail from moving.

12.Place the unassembled 5th wheel support arches/slider/goose into the already installed mounting rail. Position the forward mounting
rail with the support arches/slider/goose by inserting the tabs into the mounting rail and pushing the mounting rail tight towards the
other mounting rail. Ensure that the mounting rail is centered on the bed of the vehicle. This will position the rail in the correct
location and ensure that the 5th wheel will have a snug fit to the truck. Note: If more than one hitch product will be used with the
mounting rails then both types should be used at the same time to align the rearward mounting rail. This will ensure that one product
does not compromise the fit of the other.
13.Repeat steps 8 through 10.
14.Move the mounting rail into position. Install the 5/8”-11 x 3” carriage bolts that are supplied with the rails with .657” x
1.271” tube spacer along with the block spacer to be located in the corrugation between the box and the mounting rail or
between the box and front brackets (1) (2), through the rail and front brackets (1) (2). (Note the block spacer is to eliminate
crushing bed corrugation.) Attach 5/8” conical washers and 5/8” nut to the underside of the brackets per the illustrations
and tighten snug to keep the mounting rail from moving.
15.After fully installing the 50054 custom mounting brackets, tighten the fasteners in the following sequence. Note: Torque all
5/8” hardware to 150 ft-lbs (204 N*M) and all M12 hardware to 92 ft-lbs (125 N*M). First torque the mounting rails to
the frame brackets and then torque the frame brackets to the truck frame.
16.Reinstall electrical wire loom and brake lines. Replace inner plastic wheel well liner to body, if removed reinstall spare tire.
