TNT's long arm coil conversion upgrade for your Jeep® Cherokee XJ provides maximum performance over your factory leaf springs. Tired of your rough riding il-handling leaf springs? Are you a die hard Cherokee fan but want more from your Jeep® and its suspension? TNT's Rock-TekTM Long Arm Coil Conversion provides maximum articulation and unmatched wheel travel for ultimate off road traction and performance; all while maintaining predictable, safe and secure on-road handling.

Jeep® owner's have high expectations for their "rock-crawler" Jeep®. Street manners usually take a back seat to trail performance. At TNT we asked ourselves, why not adapt our popular TJ/LJ long arm suspension to a Jeep® Cherokee XJ? Enter the Rock-TekTM dual-triangulated coil conversion. Our design goal was simple - build a suspension that dominates any terrain and drives better than stock on the pavement.

High Performance Suspension Solution

No matter what terrain you choose, the Rock-TekTM long arm suspension design has superior geometry and components - the competition doesn't want to see this system on your Jeep® Cherokee, it is simply the best suspension design on the market. Over built parts, removable belly pan skid plate, dual triangulated rear suspension and our original Y-LinkTM front control arms give you the suspension to tackle the toughest terrain.

Finally a suspension designed for your Jeep for the way it should be driven - anywhere you want to!

Dual Triangulated TRI-4 four link

The Rock-TekTM suspension is specifically designed for tackling the most difficult terrain. The TRI-4 rear suspension is designed to cycle vertically throughout articulation to eliminate rear-steer commonly found in lesser suspensions. Aggressive geometry coupled with a flat roll center will make your Jeep stick to even the steepest climbs or radical off camber situations.

Lower arms are manufactured from 2" x 0.375" 1026 DOM tubing, to handle anything they may come in contact with, and upper arms from 1.50" X .250" 1026 DOM. All control arms have 2.50" of adjustable length and feature rebuildable Flex joints and poly bushings.

Front Y-LinkTM High-Clearance Radius Arms

All TNT long arm suspensions come with our Y-LinkTM High Clearance Radius Arms. Their original and unique design offers the following benefits:

  • Clearance over obstacles
  • No loss of turning radius
  • Allows for deeper off-set wheels

What our customers have to say..

"TNT understands all levels of the "Jeep" experience. They will build the vehicle you want and need, their suspensions perform to the very highest standards in all situations. TNT represents integrity and professionalism." - Chuck Kirkton, Gallow Wine Company

"My wife and I love our Jeep. I was so happy to get rid of the noisy, tippy 6" lift I had. I now have a 3.5" lift with more wheel clearance and a Jeep that works better both off and on the road." - Jack Nelson, President, Dawn Trucking Corp.

"TNT are wheelers who love to see things work right. For me that means getting my Jeep really robust and capable. I like extreme trails, and I want to drive my rig on the road too. They accomplished it! They are creative, fun to work with and above all know the game of making rigs work on the road and on the trail." - Pat Gruber, CEO, Gevo

"The TNT Customs Rock-Tek suspension is truly amazing and works like a dream. Both on and off-road, this engineered system is a "Cadillac" ride and performance. We found ourselves cruising through obstacles with ease and finesse." - Del Albright, Blue Ribbon Coalition




- Rear coils and shocks are to be supplied by customer.

- Rear coil height is approximately 3" shorter than front coil height (depending on spring rate). For example, TNT's 5.5" Coil Conversion uses 5.5" front coils while using 2.5" OME Heavy Rate TJ coils in the rear.

- TNT recommends that a Slip-Yoke-Eliminator be installed on your tranfer case
