RockJock JK Wrangler Unlimited 4Dr Currectlync High Steer Knuckles 2-3/4in Tie Rod & Drag Link Lift

Fix Bump Steer and Protect Your Steering Geometry on a Lifted JK

Lifting a JK Wrangler throws off steering geometry and drops the tie rod and drag link right into rock-strike territory. The RockJock Currectlync High Steer Knuckles correct that by raising both components 2 3/4 inches, restoring proper angles while moving vulnerable steering parts up and out of harm's way. Cast from premium iron and finished in gloss black, these knuckles bolt in place of the factory units and retain every stock outer component for a clean, factory-style install.

About RockJock

RockJock 4x4 by John Currie designs and manufactures heavy duty off-road steering, suspension, and axle components engineered to exceed OEM strength and durability standards.

FAQ

The RJ-437100-101 is a pair of RockJock Currectlync high steer knuckles for JK Wrangler and Wrangler Unlimited models. They raise the tie rod and drag link mounting points 2 3/4 inches to correct steering geometry on lifted Jeeps and move steering components away from rocks and trail obstacles.

They are designed primarily for lifted JK Wranglers where the factory steering geometry has been altered. On a stock height Jeep the raised geometry is unnecessary, so these knuckles are best suited to vehicles running a suspension lift.

Yes. The knuckles are designed to retain all factory outer components including ball joints, unit bearings, outer axles, brakes, and dust shields, so no additional purchases are needed for those parts.

RockJock strongly recommends installing the RJ-437100-101 as part of one of their complete high steer kits, which include a matching forged drag link and chromoly tie rod. Stock or other aftermarket rods have not been tested with this knuckle geometry.

RockJock specifies a minimum 17 inch diameter wheel with up to 6 inches of wheel backspacing to maintain proper clearance with the raised knuckle geometry.

A minimum 2.2 inch bump stop extension is mandatory to prevent components from contacting each other under full suspension articulation.

Yes. The RJ-437100-101 is compatible with factory Dana 30 or Dana 44 front differentials, as well as aftermarket axles that retain the factory spec inner C-knuckle design.

Yes. The knuckle geometry is designed to work with RockJock's ram assist bracket kits, allowing installation of a hydraulic assist steering ram in addition to or instead of a standard steering stabilizer shock.
