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.
Use only bolts, nuts, and washers supplied to install this kit. All bolts and nuts are Grade 8 unless otherwise specified.
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.
Do not install this product on or attempt to tow with a truck with a 5-1/2' bed unless a sidewinder pin box coupler has been
installed on the trailer.
Warning: When drilling holes be aware of potential risks to vehicle components above & below the truck bed and make
appropriate safe guards to protect them from damage.
IMPORTANT: Contact between any bare steel components (frame mounting brackets, U-shaped spacers, mounting rails, etc.) and bare
aluminum bed may cause corrosion over it's life. Insure that the paint is not damaged on the brackets. This kit also includes galvanic
isolators that provide an extra layer of protection- use galvanic isolator squares (11) or galvanic isolator strips (1),(10), & (12) on the surface
that will make contact with the truck bed. See Figure 4, Figure 5, & Figure 6. Repaint any areas where holes were drilled through bed.
Installation Instructions
1.) Lower and remove spare tire if extra room is needed. If equipped with inner plastic wheel well liner, remove inner plastic wheel well liners to allow access to frame.
2.) Place the galvanic isolator strips (12) on the bottom surface of each rail to protect aluminum truck bed as shown.(See Figure 3)
Note: It is important that the galvanic isolator strips (12) are installed correctly to avoid corrosion between the mounting rails and truck bed over its life.
3.) 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/ or the wheel
well and the proper distance from the rear edge of the truck. (See Figure 2)
4.) Mark and center punch the holes as per the illustrations. Move the rail out of the way and drill each position with a 1/8" drill bit. (See Figure 2) ENSURE THE 1/8"
HOLES DRILLED IN ROW 3 PASS THROUGH BOTH THE TRUCK BED AND THE TRUCK BED CROSSMEMBER
5.) Install the galvanic isolator strips (11), (10) & (1), on the frame brackets (16) & (17) . (See Figure 3 & 7)
6.) Loosely install the frame brackets (16) & (17) using the appropriate hardware and hand tighten. (See Figure 3)
1.) Place a 5/8" flat washer (8) over each of the 5/8-11 x 4-1/4" hex head bolts (6).
2.) Position the frame brackets (16) & (17) over the frame mounting holes, and route the 5/8-11 x 4-1/4" hex bolt (6) through the frame bracket
and vehicle frame from the outside of the frame to the inside of the frame as shown. (See Figure 3).
3.) Install the 5/8 conical washer (9) and then the 5/8-11 nut (7) over the 5/8-11 x 4.25 hex head bolt (6) and hand tighten.
7.) Check that the 1/8" drilled holes from step 4 align with the slots of the frame bracket (16) & (17). If holes do not align, adjust the frame brackets as needed. If this
does not align the holes, restart the installation at step 4. When the holes align with the rails and brackets, remove the rails and brackets and
proceed to step 8.
8.) Enlarge all rail bolt holes to 9/16". ENSURE THE BOLTS HOLES DRILLED IN ROW 3 GO THROUGH BOTH THE TRUCK BED AND THE TRUCK BED
CROSSMEMBER.
9.) Enlarge the holes in Row 3 in the TRUCK BED ONLY to 1-1/8".
DO NOT ENLARGE THE HOLE IN THE TRUCK BED CROSSMEMBER TO 1-1/8"
10.) Place the tube spacers (18) and 1/2 x 1 x 2 spacer blocks (3) in the Row 3 bolt locations. (See Figure 6)
11.) Reposition the mounting rail over the holes.
12.) Install the rear rail attachment bolts as shown in figure (3).Ensure that the galvanic isolator patches (11)are installed on the U-shaped spacers and spacer blocks as
shown. (See figures 4 & 5) Attach the 1/2" conical washers (14) and hex nuts (13) on the bottom side of the frame bracket (16) & (17) , as per
figure 3, and tighten snug to keep the mounting rail from moving. For the bolts in row 3 (figure 2 & 6), which goes through the truck bed cross
member/sill/hat section, route the 1/2-13 x 4.50 Carriage bolt (2) through the rail and tube spacer (18) and 1/2 x 1 x 2 spacer (3), and secure using
the .250 x 1.5 x 3 spacer (5), 1/2 conical washer (14), and 1/2-13 nut (13). For the center rail bolt in row 4 of rail attachment bolts, route a 1/2-13
x 2.00 Carriage Bolt (15) though the rail and bed, then secure using a .250 x 1.5 x 3.00 spacer (5), 1/2 " conical washer (14) and 1/2-13 nut (13).
See Figure 6 for a detailed view of the bolts in row 3.
13.) Place the unassembled 5th wheel legs/slider/goose into the already installed mounting rail. Position the second mounting rail with the
legs/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.) Mark and center punch the holes in the front mounting rail as per figure 2. Move the front mounting rail and the frame mounting brackets out of the way, and drill
with a 1/8" drill bit.
15.) Repeat steps 6,7, & 11 for the front mounting rail.
16.) Install the front rail attachment bolts and spacers as shown in figure (3). Ensure that the galvanic isolator patches are installed on the U-shaped spacers and spacer
blocks as shown. (See figures 5 & 6) Attach the 1/2" conical washers (14) and hex nuts (13) on the bottom side of the frame bracket (16 & 17) , as
per the illustrations and tighten snug to keep the mounting rail from moving. For the center rail bolt in rows 1 of rail attachment bolts, route a 1/2-
13 x 2.00 Carriage Bolt (15) though the rail and bed, then secure using a .250 x 1.5 x 3.00 spacer (5), 1/2 " conical washer (14) and 1/2-13 nut(13).
17.) Torque all hardware.
Note: Torque all 1/2" Gr. 8 hardware to 110 ft-lbs. Torque all 5/8" Gr. 8 hardware to 212 ft-lbs. First torque the bed mounting rails
to the frame brackets and then torque the frame brackets to the truck frame.
18.) Replace inner plastic wheel well liner to body, and spare tire if removed.
