California Residents WARNING

The upper control arm mounting bolts on many Nissan Trucks and SUV's are frequently corroded and must be cut out when removing or replacing the control arm. This hardware replacement kit (2) allows easy re-installation of the upper control arm. The pair of bolts and nuts are enough to replace both bolts in one corner or to replace the rearward bolt on both upper control arms if you are cutting them out to replace both arms.

California Residents WARNING

This replacement front adjustable strut rod is easily adjustable and gives these popular tuner vehicles the ability to change caster by 3°. A stiffer rubber bushing material provides better handling in performance applications.
