Product Details

The complete TeraFlex JK: Dana 30/44 High Steer System w/ HD Forged Drag Link Flip Kit & HD Chromoly Tie Rod Kit addresses all the front-end steering issues associated with lifted JK 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 models with 4” or more lift.

These High Steer Knuckles maintain correct steering geometry angles for superior highway drivability. Tie Rod ground clearance is increased by more than 1-1/8” to prevent tie rod damage and bending. Cast from heavy-duty ductile iron and reinforced in areas prone to stress and deflection.

“Flipping” the HD Forged Drag Link (50% stiffer than factory) over the Knuckle helps eliminate front-end shimmy and other alignment issues. The axle end joint is flipped 180 degrees so it can be pressed down into the top of the knuckle.

The Front Track Bar Drop Bracket lowers the Front Track Bar mounting point to correct steering geometry for superior highway drivability. Multiple track bar mounting holes allow you to fine tune the track bar angle to reduce bump steer and other front-end issues. The Frame Brace and Brace Bar reinforce the frame further reducing front end shimmy and excess frame movement.

Teraflex's complete High Steer System (# 4391000) combines our High Steer Knuckle Kit (# 4390870) with our complete HD Forged Drag Link Flip Kit (# 1853905), Front Track Bar Drop Bracket & Frame Brace Kit (# 1600444), HD Chromoly Tie Rod (# 1853910), and Steering Stabilizer Relocation Mounting Bracket (# 1123160). Most replacement components available separately.

Compatible with all factory and aftermarket axle shafts, ball joints, wheel hubs, and tie rods. Does not affect operation of factory stability and traction control systems including ESP and ABS.
