No matter what terrain you choose, TNT's Rock-Tek™ Long Arm Suspension for your Jeep® Wrangler TJ design has superior geometry and components - the competition doesn't want to see this system on your Jeep® TJ, it is simply the best suspension design on the market. Over built parts, removable belly pan skidplate, dual triangulated rear suspension and our original Y-Link™; 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-Tek™ 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 rebuild-able Flex joints and bushings.
*Due to control arm placement and triangulation exhaust modifications are required.
Front Y-Link™ High-Clearance Radius Arms
TNT Long Arm Suspensions come with our proven Y-Link™ 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
Driver's side Y-link arm provides driveshaft protection on High Pinion axles.
Fully adjustable components allow for pinion angle and wheel base configuration
5pc High Clearance Modular Belly Pan System
TNT Rock-Tek™ long arm suspensions come with our innovative 5 piece modular belly pan system. The belly pan system is the new mounting point for all control arms for the long arm suspension. This unique design offers the following benefits:
Removable skid plate - without supporting the transmission
Independent transmission crossmember
Stand alone rear suspension crossmember
Transmission and Transfer case service without removing the suspension
Our high clearance pan* gains 1 3/4" over stock on 97-02' models and nearly 3" on 03'-06 model years. TNT Rock-Tek™; long arm suspensions come with a weld on, full length rear axle truss assembly that fits your rear axle. Our axle truss assembly includes our Tri-4 mount, coil mounts as well as new lower control arm mounts and shock mounts. The competition claims they have a truss for their triangulated rear suspensions; however, it really is just a bolt on bracket attached to failure prone stock bracketry. Don't be fooled, pick a suspension design that actually has a truss that welds on - yes it adds some work to the installation - the resulting piece of mind that comes from the extra work is worth the effort. An added bonus of a weld on truss assembly is an axle housing that is fortified against bending that can be caused by extreme terrain coupled with over sized tires.
Our Rock-Tek™ Long Arm Suspension Upgrade is designed for those wanting to upgrade to a high quality long arm suspension without limitations. This upgrade will provide a noticeable improvement in on road handling, returning your Jeep® to better than stock. On the Rocks you can expect a significant improvement in the ability of your Jeep®, even in the most extreme situations. If you want more rear wheelbase right out of the box, select a Rock-Tek™ rear wheel base stretch upgrade when placing your order. This kit comes with longer control arms and new upper rear coil mounts giving you a way to get to the magic 100" wheelbase.
*Installation of our High Clearance bellypan requires an 1-1/4" Body lift and Motor lift.
