Jeep JKU Seat Slammers DESERT DOES IT Jeep 2007 - 2018 JKU 4 Door Models Only — Install Guide

Important Notes

• Read all instructions thoroughly before beginning. Evaluate whether you are experienced and capable of performing these modifications. A factory service manual should also be used in conjunction with these instructions.
• The seat weight sensor is extremely sensitive. Handle the seat carefully. Do not drop the seat or sit in the seat while it is on the floor. If the sensor is damaged, replace the unit. Failure to do so may result in personal injury or death.
• If you perform the full drop, the outside seat trim may rub against the B-pillar plastic trim when the seat is pumped all the way down. Raising the seat one pump will prevent interference.
• Before installation, verify there are no obstructions under the seat that would prevent the seat from being fully lowered. Although the product has been verified on several models and trim levels, mid-year or trim changes may vary.

Step 4 — Remove the Seat from the Vehicle

1. Gently and carefully remove the seat from the vehicle.
2. Place the seat upside down on a flat work surface.

Step 5 — Mark the Seat Rail for Cutting

1. With the seat upside down, measure 1.5 inches from the rear seat rail bolt.
2. Mark the cut line on the seat leg.
3. Repeat this process on both seat legs.

Step 6 — Verify the Cut Line

IMPORTANT:
Double-check that the cut line matches the provided installation photos. If you are not 100% confident that the cut line is marked correctly, do not proceed.

Step 7 — Prepare to Cut the Seat Rails

IMPORTANT:
Cutting the seat rails is a permanent modification. Triple-check that all measurements and markings are correct before proceeding.

Step 8 — Cut the Seat Rails

1. Using a Sawzall with a metal-cutting blade or an angle grinder with a cutoff wheel, cut the seat leg along the marked cut line.
2. Repeat on the opposite seat rail.

Step 9 — Install Seat Slammer Legs for Drilling

1. With both rear seat rail legs cut off, remove the 2x 13mm flange nuts securing each seat rail to the seat.
2. Place a Seat Slammer Leg onto each seat rail.
3. Reinstall the 13mm flange nuts.
4. Using the Seat Slammer Leg as a guide, drill the third hole through each seat leg with the 5/16" drill bit.

Step 10 — Repeat on Both Seat Rails

Step 11 — Clean and Protect Cut Areas

2. Install the provided 2x Button-Head Bolts, 2x Flange Nuts, and 2x Fender Washers through the holes drilled in Step 9.

Step 13 — Torque Seat Slammer Hardware

1. Torque all six flange nuts to 25ft-lbs.

Step 14 — Prepare the Vehicle Floor

1. Before placing the seat back into the vehicle, position the two Front Wedge Shims on the floor where the forward seat legs mount.
2. Make sure the thickest part of each wedge faces toward the front of the vehicle.
3. Place the Seat Slammer Spacer on the floor at the rear mounting location nearest the transmission tunnel.

Step 15 — Reinstall the Seat

1. Carefully lift the seat from the work surface and place it back into the vehicle.
2. Make sure the seat legs are positioned correctly on the Front Wedge Shims and Seat Slammer Spacer.

Step 16 — Install Front Factory Bolts

1. Loosely reinstall the factory bolts into the same threaded holes they were removed from.
2. The bolts pass through the seat legs, through the Front Wedge Shims, and into the vehicle floor.

Step 17 — Install Rear Bolts

1. The rear door-side Seat Slammer Leg does not require a spacer. Reuse the factory bolt.
2. On the transmission-tunnel side, install the provided M12 flange bolt.
