TeraFlex JK: Dana 30/44 High Steer System w/ HD Drag Link Flip Kit & HD Tie Rod Kit

The complete TeraFlex JK: Dana 30/44 High Steer System w/ HD Drag Link Flip Kit & HD 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.

“Flipping” the HD Drag Link (50% stiffer than factory) over the Knuckle helps eliminate front-end shimmy and other alignment issues. 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.

Our complete High Steer System (# 4391000) combines our High Steer Knuckle Kit (# 4390870) with our complete HD Drag Link Flip Kit (# 1853905), Front Track Bar Drop Bracket & Frame Brace Kit (# 1600444), HD Tie Rod (# 1853910), and Steering Stabilizer Relocation Mounting Bracket (# 1123160).
