Rusty's XJ Cherokee 4-Link Long Travel Upgrade
Rusty's 4 Link Long Arm Upgrade kit is designed for individuals who already have the amount of lift they need and simply want to upgrade their control arms to a 4 link long-arm system. Works with all brands of suspension kits. The High Clearance Long Arms require at least 5 inches of lift but the standard arms will work from 4 inches or larger lifts.
The Rusty's Off Road long travel suspension is going to be tough to beat! It takes you places other vehicles can't go; over logs, big boulders or over just about anything else on the trail. We have applied race technology and over 4 years of research and development to deliver a suspension system with enough articulation to keep your rig firmly planted even over the most radical terrain.
The system starts with new 4 Link lower and upper control arms that are completely adjustable on both the control arms. The arms utilize Clevite factory rubber control arm bushings at one end to ensure that no noise or vibrations are transmitted through the unibody and at the other end Rusty's rebuildable Flex Joints for superior flex and articulation. The massive lower arms are constructed of 2" diameter heavy-wall D.O.M. tubing, while the upper arms are constructed of 1.50" D.O.M., so go ahead and bash them against rocks and ledges because they can take the abuse and keep right on going!
The new control arms bolt to a new 1/4-inch thick laser-cut steel 3-piece crossmember with a removable center section. This new design offers easier service and maintenance and is also surrounded by Rusty's frame reinforcement brackets. The 3/16" laser cut CNC formed reinforcement brackets are located on both the outside and the inside of the unibody and basically sandwich it, tying the unibody and the new crossmember together as one solid unit. This design distributes the extreme loads from the suspension over a much larger area of the unibody and assures many years of extreme four-wheeling without any structural damage to the unibody. The crossmember's design does not reduce ground clearance and also drops the transfer case relieve driveline angles. Our optional Transfer Case Skid Plate can be easily added for further protection and support.
Due to the thickness of the Jeep unibody, we've designed our long-arm kits to be completely bolt-on. Although it is possible to weld to the unibody, the longevity of the weld in questionable. The unibody is only 16 gauge (.060 in.) and the heat of a weld stresses the thin metal. Even though the weld itself may not crack, the unibody around it may. While the unibody is welded from the factory, this was done with precision robotically-controlled welders with heat sensors to create welds that were much more precise than even the most skilled human welder. Our bolt-on systems are not only more durable than a weld-on system due to the extensive reinforcement involved, but they are also much easier to install. The Rusty's reinforcement brackets creates a larger surface area that distributes stresses over a larger area than a weld-on installation. In addition, we use adjustable control arms that not only allow easy caster adjustment but also incorporate pivot points designed for suspension flex, which further eliminates stress on the unibody mounts. With Rusty's having over 40 years in business, engineers and design specialist and complete in house manufacturing you can expect the quality and craftsmanship you demand for your Jeep.
