Our billet aluminum spring cup fits better than most steel styles for a more secure and precise fit.  Plus it utilizes a COM12 roller bearing to reduce the friction on pivoting on the jackbolt.  This is a NECESSITY when using soft front springs- as they need free movement to compress correctly and linear.  Fit our steel 1"-8 jackbolts as well as others.  Capable of working with 1 1/8" fine thread jackbolts by purchasing optional adapter bushings (select this option and they will be automatically added).  Available to fit 5" and 5.5" springs.  Jackbolts not included.

FEATURES:

• Lightweight aluminum design with lightening pockets
• Teflon lined roller bearing- no lube necessary

• Simple economical design
