The 2.5 IFP model is a simple bolt-on upgrade over OEM shocks. They are a gas-pressurized design with internal floating piston to help prevent cavitation and fading.
This configuration is for use with stock geometry and can accommodate 0 in. to 2 in. of lift with either stock or aftermarket upper control arms.
Ride height is preset from our factory at approximately 1.5 in. of lift for a stock truck with stock tires, actual ride height may vary depending on wheels dimensions and upper control arms used.
Package includes two (2) side-specific rear shocks
**All Elka Suspension components are made to order. Please contact us for current lead times. We will contact you at time of order to learn about the specifics on your build so the suspension is properly tuned to your vehicle.
