Lets talk about joints and bushings. The factory style rubber joint, is a great joint style for ride comfort and vibration dampening; but it falls short in the articulation category. The Factory rubber joints are in essence a rubber bushing fused to a steel core. Since the steel core is fused to the bushing, when the axle moves, it stretches and twists the rubber. Once we start demanding more out of the truck in terms of articulation, this becomes a limiting factor, as there is limited movement allowed by the bushings design. Over time the added stress will deteriorate and tear the rubber causing the joint to fail.

Description

Apache Offroad’s Rear Extended Upper Control arms are used to correct the pinion angle after a 1-3.5″ lift is installed on a vehicle, as well as increasing articulation due to the offset eliminating the arm from binding with the fuel tank.

INCLUDES:

2 UPPER REAR FIXED CONTROL ARMS

All of our Control Arms are fabricated out of DOM Heavy Wall Tube; not a marketing gimmick, just the real deal:

Upper Control Arms- 1.25″ x .120″ DOM Tube

To put this in perspective- Most rock sliders are made out of .120 wall tube, with many brands being made out of Hot Rolled (HREW) tube, which is not as strong as DOM and quite a bit less expensive to use in manufacturing.

Our Control Arms are available with two joint/bushing options: Polyurethane and the MetalCloak Duroflex Joint.

Polyurethane:

Poly bushings are our least expensive joint / bushing option available. They are commonly used in aftermarket applications such as front upper control arms, and are quite popular in the racing world because of their firmer and long lasting nature. They do absorb some vibration, but not as well as the factory bushings nor the Duroflex joints. They are great for on/offroad use, though do not allow for as much articulation as the Duroflex joints do. They are also easily replaceable and low cost. The downside is that poly is prone to squeaking and must be lubricated every so often. A grease zerk is conveniently located at each end of our Control Arms to make greasing them a breeze.

MetalCloak Duroflex Joint:

If your goal is to maximize travel and articulation in the rear axle, but still want on-road driveability, these are the joints you want. The Duroflex joint combines the benefits of the factory style rubber joint with the flexibility found in heim style joints, generally used in the racing and heavy duty offroad rigs. These joints offer a ton of unrestricted movement, do not require grease for quite operation, and absorb vibrations better than Polyurethane bushings. They are also easy to replace, though are more costly when compared to Poly bushings.
