CAUTION: HANDLE WITH CARE.
To ensure our customers receive all components with full integrity, we pack
the motors separate from their linkage assemblies. This requires that the
installer position and fasten the motor before continuing with the install.
Please follow the instructions below and handle the assembly carefully.
CAUTION: Dropping the assembly or any excessive impact MAY cause damage
to the motor.
Instructions:
- Position the gear cover in place as shown if not already in place.
- Seat motor into position on the three mounting bosses. This may require an adjustment of the gear by moving the swing arms.
- After seating into place, fasten the motor with the three motor mount screws with 4mm Hex Head. Tighten screws to 36 in-lbs (4N-m). Do not over torque.
PARTS
INSTALLATION
NOTE: 1500 RAM Only! Powerstep installations require additional steps and come with the required additional hardware. Please read and carefully follow the instructions in Step 1 for your vehicle model. Follow Steps 1-5 to relocate brake cable and wire harness plug and then proceed with the Power Step installation. For Ram 2500/3500 Skip to step 6.
-
RAM 1500 ONLY. On Drivers side of vehicle towards front of body remove harness bracket with 10mm socket or wrench. Remove plug from bracket. And replace with supplied bracket using two of the three factory screws.
-
While holding brake cable adjustment nut with wrench (located on driverside along frame, towards the rear), loosen brake cable to allow for slack. Mark position of nut before loosening.
-
After gaining enough slack, detach brake cable as shown below. This detachment point is located just to the rear of the adjustment nut.
-
Remove brake cable guide from frame by depressing locking tabs and sliding guide out through hole. Unthread brake cable from frame mount.
-
Attach brake cable guide to supplied Brake Cable Bracket (27) and mount bracket with supplied hardware. Reattach brake cable and readjust brake cable adjustment nut to original position.

HARDWARE MOUNTING OVERVIEW (passenger side shown)
Locate forward most and rearward most mounting provisions on inner sill of truck. Remove tape from sill drain hole at both mounting points.
Note: Some vehicles may have Front welded fastners installed already. Backing plates and rivet nuts are not needed in these locations. Factory Rivet nuts will need to be removed to install backing plates. -
Set Reinforcement Plate in place and locate with rivet nuts. Drill hole using an 1/8” drill bit. After drilling apply paint to prevent rusting.
-
Once hole is drilled insert a piece of string or wire through hole in the Reinforcement Plate. Set plate into position.
-
Set rivet nuts into place for alignment. Insert pop rivet through hole in plate and secure in place. Once pop rivet is installed remove string or wire from the Reinforcement Plate. NOTE: Verify plate is pulled flush to the body before securing pop rivet.
-
Assemble Hex Bolt (lubricated with soapy water), Washer, Rivet Tool, and Rivet Nut together as shown and place into hex cutouts in sill. An extra Hex Bolt and M8 Washer is supplied to install rivet nuts.
-
With Rivet Nut Tool held in place with 19mm wrench, tighten Hex Bolt until Rivet Nut deforms and secures itself to the sheet metal (110 in-Lbs. or 4 turns). Remove Hex Bolt and Rivet Nut Tool. Repeat for each of the four mentioned mounting locations.
-
Once rivet nuts are in place use a screwdriver to push back tab in hole to avoid interference with linkage mount.
-
Linkage Installation: On rear linkages thread front hex bolt into rivet nut with washer. Note on Front drive linkages both hex bolts can be threaded into position.
-
Rear Linkage: With linkage in position insert Hex bolts into rivet nut locations. Snug bolts but do not tighten.
Note: Pre-threaded bolt will attach to slot centered on linkage. Idler linkages will use 2 of the 3 mount points. -
Front Linkage: On Vehicles that have crash bracket remove bolts attaching bracket to inner sill of truck. Thread hex bolts into position as in step 13.
-
If crash bracket is not present use supplied spacer in place of bracket. Spacer can be inserted after linkage is up into position. Spacer will be held in place by drilling and pop riveting into place. Rivets will be installed in step 40 & 41.
-
All Linkages: Slide linkage over pre threaded bolts. Using a T27 Torx driver start torx bolts and washers. Snug bolts but do not tighten. Replace bolts from step 15 if present.
-
Using a 13mm wrench tighten two hex bolts on linkage. Torque to 16 ft-lbs. Torque bolts from step 15 if present to 50 flt-lbs.
-
Using a T27 Torx driver torque bolts to 6 ft-lbs.
-
The jogs in the lower part of the linkages point toward one another, as shown. Note: Linkage position described in parts list on page 3.
-
Install boards: Open doors to retract both linkages. Slide mounting T-Nut of board into position and attach to linkages. Shift board forward as much as possible for proper clearance. The end of board/end cap will nest into linkage lower mount 1/2” when positioned correctly. With boards in extended position step on boards to seat linkages. Walk the length of the board taking bouncing steps. DO NOT JUMP ON BOARD! Verify that board end caps do not contact the pinch weld. If Endcaps make contact loosen 4 button head screws at pinch weld. Walk the length of the board and apply weight to the center of the board and while applying weight retighten button head screws at pinch weld.

POWER-DEPLOYABLE RUNNING BOARDS OPERATION: AMP Research PowerStep running boards automatically move when the doors are opened to assist entering and exiting the vehicle.
-
Automatic power deploy:
The running boards will extend down and out when the doors are opened. -
Automatic power stow:
The running boards will return to the stowed position when the doors are closed. There will be a 2-second delay before the running boards move to the stowed position. -
Automatic stop:
If an object is in the way of the moving running board, the running board will automatically stop. To reset, clear any obstruction, then simply open and close the door to resume normal operation. -
Manually set in the deployed (OUT) position for access to the roof: The running boards can be manually set in the deployed position by firmly holding the step down with your foot While at the same time closing the door. To resume normal operation, open and close the door.
