Reinforces inner knuckle on axle housing; Attaches directly to front axle tube and inner steering knuckle on Jeep JK DANA 44 and DANA 30 axles. Adds much needed strength to help prevent the common bending of the inner C while off-road. These gussets also stiffen up the area around the upper ball joint, preventing deflection from the stress of larger tires. The gussets attach to the front lower "corners" where the inner knuckle meets the axle. Mild steel 5/8" thick; Bare metal; Weld-on; Sold in pairs.
