The TeraFlex JK: Dana 30/44 High Steer System w/ HD Forged Drag Link Flip Kit addresses all the front-end steering issues associated with lifted JK Wrangler/Unlimited models. Highly recommended for JK models with 4” or more lift.

The TeraFlex JK: Dana 30/44 High Steer System w/ HD Forged Drag Link Flip 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 Upper 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 Front Right Frame Brace and Front Frame Brace Bar reinforce the frame further reducing front end shimmy and excess frame movement.
