At UMI, we believe that not all springs are created equal. That's why our line of front and rear springs are designed to be the best in the business. Working with a top Sprint Cup chassis engineer, we have created springs that offer superior performance and handling. Our front springs are made from 5160 CrSi premium wire and have a linear rate of 600 lb/in. The rear springs are constructed from 9254 CrSi premium wire with a linear rate of 130 lb/in. This design ensures consistent handling characteristics, reducing body roll and eliminating that "floating" feeling often experienced with G-body vehicles. Perfect for Auto-x, Pro-Tour, and corner carving/cruising applications, our springs are engineered for a 2" lowering with standard SBC and LS power. For Big Block applications requiring a ¼" nose down rake, our front springs are also suitable. With a tough black powder coat finish, these springs are built to last and proudly manufactured in the USA. Experience the difference with UMI's premium quality springs, featuring consistent rates, premium materials, and exceptional performance. Say goodbye to the floating feeling and hello to superior handling for years to come.
