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