Description

Rusty’s JK Adjustable Front Upper Arms are fabricated from 1-1/2″ DOM tubing and have a CNC mandrel bend to offer more flex and articulation. 1.25″ x 12 threads are used in the arms and on our forged ends for strength and easy adjustability. The forged ends utilize our Flex joints, which offer better suspension flex, adjustable pre-load settings, and are greaseable. The Flex Ends are secured with the supplied jam nuts. The arms themselves come powder coated in a glossy black finish.

Rusty’s heavy duty front control arms are the some of the most affordable on the market, while adding necessary strength to the front end.  The last thing you want when you offroad a lot is a bent arm, as this affects your alignment and your vehicle will not track straight down the road.  With 5mm thick wall tubing, you can’t go wrong with a set of these.

The Rusty’s Forged Flex Ends were designed and manufactured with quality, reliability, and strength as our first priority.

The Forged Flex Ends feature 1.25″ x 12 threads, locking jam nuts, our proprietary compound bearing races, and a chromed spherical bearing. These outer casing of the forged ends offers over 100,000 psi of strength. No wimpy snap rings here, Rusty’s was the first to design and manufacture an end without snap rings; we use only threaded adjustable retainers that are CNC machined for a perfect fit. The adjustable spanner nut allows you to dial in the perfect amount of pre-load. To adjust the pre-load, simply tighten the spanner nut to the desired pressure, line up the groove in the preload nut with the set screw, and then tighten the set screw.

Rusty’s proprietary compound bearing races provide high strength and a superior fit while being much more durable than other poly style races. The plated Chrome Moly (short for Chromium Molybdenum) spherical bearing offers long life, high strength, and adds to the end assembly’s great flex. All rod ends come with grease fittings. Be sure to grease the joints regularly for a lifetime of quiet, reliable service.

Since all moving parts wear, Rusty’s offers inexpensive rebuild kits for all the moving parts of the joint.
