No matter what terrain you choose, TNT’s Rock-Tek Long Arm Suspension for your Jeep Cherokee design has superior geometry and components – the competition doesn’t want to see this system on your Jeep XJ, 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 inch x 0.375 inch 1026 DOM tubing, to handle anything they may come in contact with, and upper arms from 1.50 inch X .250 inch 1026 DOM. All control arms have 2.50 inch 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
3pc High Clearance Modular Belly Pan System
TNT Rock-Tek long arm suspensions come with our innovative 3 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 inch over stock TNT Customs Rock-Tek long arm suspensions come with a weld on 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.
