MOUNTING RAIL KIT
SPECIAL NOTE: On 1999-2001 Chevrolet Silverado and GMC Sierra applications, it will be necessary to
modify the bolt installation procedure on the forward driver side bracket attachment. Drill a 5/8” diameter
hole in the frame rail at the lower bracket attachment point. Place (1) of the 1/2” wheel bolts in the 1/4” spacer
(CM-SP50). Place this bolt assembly into the frame rail so that the threaded end of bolt protrudes out through
the frame rail. Bolt bracket in place at this location. The remaining bolts will be installed as normal.
9. Place the wheel bolts into the frame rail first and then out through the
brackets as shown on first page. Some applications will require the
use of a fishwire to align the bolts into the drilled holes in the frame.
Thread the fishwire coil over the end of the wheel bolt and pull through
the frame rail and bracket. See fishwire diagram. Secure each bracket
to the truck frame rail with 1/2" hex flange nuts. The knurled portion of
the bolts will lock into the frame holes as the nuts are tightened.
Use of an air wrench will simplify installation.
10. Torque all 1/2" attachment bolts to 75 lb-ft.
11. Check each hitch pin for freedom of movement in the bed rail connection. Remove the (4) pins and lift
the 5th wheel up out of the mounting rail slots. If tabs are tight in mounting rail slots check to be sure
the mounting rails are parallel to each another and square. If not, loosen 5/8” bolts and adjust mounting
rails. Also check that the 5th wheel legs are sitting vertically straight. It may be necessary to shim the
5th wheel legs by placing a washer between it and the 5th wheel head.
12. Re-torque the 5/8” bolts to 150 lb-ft if loosened in step 11.
Mounting Rail Installation Tips by Vehicle
Due to variations in vehicle assembly through the years listed, the under bed cross member location on your
truck may not be the same as listed below. The following information is to be used as a guide for placement
of the mounting rail system. Slight adjustments to these positions may be required.
Dodge Applications
1993-Earlier Dodge full size truck (ahead of axle installation)
Position the assembled 5th wheel (with mounting rails) so that the center line is approximately 2” ahead of the
truck axle center line. The rear mounting rail should be located 32-1/2” from rear edge of bed on all trucks.
The left and right angle brackets can be positioned at any location that will allow them to clear obstructions on
the truck frame rail.
1994-2001 Dodge short bed full size truck (ahead of axle installation)
Position the assembled 5th wheel (with mounting rails) so that the rear mounting rail is located 25-3/16" from
rear edge of bed.
1994-2001 Dodge long bed full size truck (over axle installation)
Position the assembled 5th wheel (with mounting rails) so that the rear mounting rail is located 29-3/16" from
rear edge of bed. Note
: On some long bed applications, the edge of the under bed supports may not allow
the formed angle brackets supplied with the bed rail kit to align with the bed rail attachment points.
The use of (2) straight “L” brackets at these location, will eliminate this issue.
Toyota Applications
2000-04 Toyota Tundra long and short bed truck (over axle installation)
Position the assembled 5th wheel (with mounting rails) so that the centerline is over the truck axle. The rear
mounting rail should be located 30-7/8" from rear edge of bed on all trucks. The left and right angle brackets
will be placed at the rear attachment points and the straight brackets will be at the forward attachment points.
