High Steer Systems

The TeraFlex JK/JKU Complete High Steer System addresses all of the front-end steering issues associated with lifted JK Wrangler and JKU Wrangler Unlimited models. This system beefs up the steering components of the Dana 30 or Dana 44 front axle, helps maximize steering component ground clearance, and restores correct steering geometry for superior highway drivability. Highly recommended for JK and JKU models with 4” or more lift.

“Flipping” the Heavy-Duty Drag Link (50% stronger than factory) over the Knuckle helps eliminate front-end shimmy and other alignment issues, while the Front Track Bar Drop Bracket corrects steering geometry. The Frame Brace reinforces the frame further reducing excessive movement and front-end shimmy. The new Drag Link threads into the factory adjusting sleeve and uses a tapered insert to mount to the Knuckle.

This kit is compatible with all factory and aftermarket axle shafts, ball joints, wheel hubs, and tie rods and does not affect the operation of factory stability and traction control systems including ESP and ABS.

Our most comprehensive kit combines our High Steer Knuckle Kit with our complete Drag Link Flip Kit, Front Track Bar Drop Bracket & Frame Brace Kit, Heavy-Duty Tie Rod, and Steering Stabilizer Relocation Mounting Bracket. Other configurations are available.
