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
- Fits tightly to most springs
- Simple economical design

Best spring cups on the market!
Bought these for my street stock and my modified. They are light weight, and easy to adjust with the spherical ball.
