The Zone Offroad Products Coil Alignment Kit will keep your coils secured, and keep them from popping out at full droop. The rear coils are known in some cases to pop out at full droop because of bowing. As the coil bows, an incorrect coil loading results causing a diminished spring rate which will result in a reduced height.
The Coil Alignment Kit rotates the lower coil mount by 10 degrees to ensure that your coil stays straight and true throughout wheel travel.
This kit is fabricated from 3/16" steel, and installation difficulty is considered to be at a simple level.
