Rock-Slide Engineering TUNDRA SERIES – STEP SLIDER - Manual (Page 4)

Installation Instruction RSEI 131
b. With bracket in the correct location, mark the location of the holes with a
marker on the panel of the truck. These will be the locations for the nutserts to
be installed in the body.
6. Carefully drill a 7/32’’ pilot hole into the center of the marked points into the truck’s
rocker side
a. **It is extremely important these holes are drilled precisely to insure the
slider will fit properly once the nutserts have been installed
7. From the center of the pilot hole, step up the hole size using a ½” bit to create a finish
hole that will be used to install the nutserts
8. Install nutserts in the holes that were just drilled into the body of the truck
a. We suggest using a crimping tool to optimize the integrity of the nutserts to
support the slider
b. If no crimping tool is available, follow these instructions
i. Install by using a 5/16’’x1.125’’ minimum length bolt with a 3/8’’ nut
ii. Put a small amount of grease on the bolt to reduce friction
iii. Hold the nut steady with an end wrench so the flange of the insert is flush
against the body panel
iv. Tighten the bolt against the nut to crimp the nutsert into place
v. If the nutsert is rotating, place a star-lock washer between the 3/8’’ nut
and nutsert
vi. Once the nutsert is crimped into place completely back out the bolt
vii. If the nutsert ever breaks loose and spins, repeat the process and crimp it
tighter to prevent spinning
Nutserts properly installed
