Product Details

The TeraFlex JK/JKU Dana 30 and 44 High Steer System addresses all of the front-end steering issues associated with JK Wrangler and JKU Wrangler Unlimited models with 4-6 inch lift kits by maintaining proper steering geometry for superior highway drivability.

Flipping the Drag Link (50 percent 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 comprehensive kit combines our High Steer Knuckle Kit with our Drag Link Flip Kit and Front Track Bar Drop Bracket and Frame Brace Kit.

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