Doberman Racing’s Jeep Liberty lower rear controls arms combined with the Barnes 4WD Enduro:
- Offer the most flex at 80 degrees per control arm.
- Are the strongest control arms on the market.
- Can be rebuilt without needing to replace the entire joint.
- Fully adjustable without needing to be removed or unbolted from the Jeep.
- Greasable via zerk fitting
- Reduce the transfer of road noise (NVH) into the cabin compared to a heim joint.
- 1″ longer thread for more adjustment compared to heim joints on the market
These Jeep Liberty control arms are made from 2″ diameter DOM steel tubing with a 0.25″ Wall thickness and you have the option of selecting between a few different set ups. They will replace the lower control arms connecting your rear axle. You may select between a Barnes4WD Enduro Joint and a Forged Poly Joint.
Both joint options come with a 1.25″ thick shank and 9/16″ bolt hole. These joints on our control arms will improve your rear suspension flex dramatically. Your vehicle will feel more stable and planted. Especially if your current control arm bushings are worn out.
When Barnes 4WD designed the rebuild-able Enduro suspension joint they combined the best materials, the best manufacturing processes and the best steel and polyurethane treatments available all in one joint. The body of the Enduro Joint is Forged 4140 heat treated Chromoly steel. They did not try to cut any corners by making a short threaded shank like a heim joint instead they give you 3.25″ of 1.25-12 threaded shank. The Enduro Joint s ball is made from 52100 bearing steel and incorporates the high misalignment spacers all into one piece of steel that provide 40 degrees of misalignment. Forty degrees of misalignment will net almost 16.5″ of travel on a two foot control arm. The spherical bearing is then Hard Chrome plated to provide an ultra smooth surface and has proven to provide excellent corrosion protection. The mounting width of the Enduro Joint is 2 5/8 and accepts a 9/16″ bolt. The cups that the spherical bearing rides on are an 88 durometer polyurethane that ensures maximum life, no squeaks like heim joints and they help to dampen axle vibrations felt through the chassis. The body of the joint and the spanner nut are gold zinc plated to ensure that the Enduro Joint looks great for the life of the joint. Once the joint is fully assembled we are still not finished making the ultimate joint. Every completed Enduro Joint assembly is then Cryogenically Treated to give the Enduro Joint the most strength and greatest wear characteristics possible.
Forged Poly Joint
They are forged from one piece of 1045 steel, making them much stronger than other inferior joint designs that have the threaded shank welded on. A yellow zinc plating is applied to help prevent corrosion, the inner sleeve has the same coating and is a one piece machined design, not a rolled piece of uncoated steel like most polyurethane joints include. A grease fitting has been integrated to make lubrication an effortless task. These joints are perfect to use on the frame end of your suspension links to help stop the transmission of vibration into the passenger compartment.
Did you lift your liberty and are now having difficulty getting a proper pinion angle? These rear lower links are fully adjustable allowing you to dial in the perfect pinion angle for your rear drive shaft. This will reduce vibrations and increase the life of your u-joints.
Have your OEM control arms rusted apart or have you worn out the cheap rubber bushings they come with? These are fully rebuildable so if you manage to wear out the joints you can purchase a rebuild kit from us.
