JKS Knuckle Gusset

Weld-on Knuckle Gussets from JKS Manufacturing eliminate bending of the inner knuckles on the front axles of Wrangler JK models. These heavy-duty profiled gussets are welded directly to the inner knuckles and axle tubes to dramatically increase inner knuckle strength while extending the life of ball joints. Knuckle Gussets are laser cut from 5/8” thick steel to guarantee precise fitment on factory Dana 44 or Dana 30 front axles.

Note: Compatible with OE Dana 30 or Dana 44 front axle. Due to variations in both the factory axle and aftermarket products, some grinding / fitting maybe necessary for best results. Install gussets before bending of inner knuckles occur to prevent replacement of axle housing. Whenever possible, upper and lower gussets should be installed together for maximum strength and reinforcement.
