Description
The 2.5” Elka OEM Factory Series coilovers for the Chevy Silverado / GMC Sierra 1500 are direct bolt-on replacement shocks intended for maximum performance. These coilovers are specifically designed to optimize off-road performance without compromising on-road handling. The shocks are adjustable for 2″-3” of lift and includes all necessary hardware needed for installation.
Specifications
For best performance the coilovers should be set at mid-shaft or about 2″ over stock height.
- Allows for 2″-3” of lift | Must be used with aftermarket UCA
- Up to 25% increased wheel travel over stock
- Extra ¾” of down travel
- We do not recommend setting the pre-load on the shock for more than 3″ of lift. Excessive preload over articulates the stock components, reducing ride quality significantly and causing premature wear on the components.
