UMI Performance 78-88 G-Body Lowering Spring Kit 2in LoweringA spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. Our front springs are wound from 5160 CrSi premium wire and feature a linear 600 lb in rate. The rear springs are wound from 9254 CrSi premium wire and feature a linear 130 lb in rate. The linear rate provides consistent handling
A spring is a spring right? Wrong! When UMI chose to manufacture our own line of springs we went all out. Designed in conjunction with a leading Sprint Cup chassis engineer, these springs are the best in the business. Our front springs are wound from 5160 CrSi premium wire and feature a linear 600 lb/in rate. The rear springs are wound from 9254 CrSi premium wire and feature a linear 130 lb/in rate. The linear rate provides consistent handling characteristics which are important for Auto-x and Pro-Tour applications while the increase in stiffness reduces body roll and prevents the “floating” feeling so common with the G-Body. These springs are suitable for Auto-x and Pro-Tour applications as well as corner carving/cruising. The ride height is engineered for a 2” lowering with standard SBC as well as LS power (lightened cars may require spring trimming). The front springs are also suitable for full weight Big Block applications when ¼” nose down rake is desired. They have a tough, black powder coat finish and UMI proudly manufactures these premium quality springs in the USA. V6 Turbo Grand National may require spring trimming due to lower engine weight.This Part Fits:

Pillow explosion
Color: White, Size: King (Pack of 2)
Pillows were extremely comfortable until one exploded while sleeping.Otherwise it would get 5 stars. Having to return kind of a pain. As they come compressed.

Not for hot sleepers
Color: White, Size: King (Pack of 2)
They’re comfortable and keep their shape, but they are not cooling pillows. 10 minutes after laying your head on it. You can feel the heat radiating back . I wake up every night with my head soaked with sweat.

Good set
Color: White, Size: King (Pack of 2)
Soft and fluffy! I like the ability to add or remove filling via the zippers. All pillows should have this!
