The Jegster lift bars dramatically increase your traction by utilizing axle torque to lift the chassis of your car and push your rear tires into the ground. These bars are designed to relocate the ''instant center'' of your rear suspension to a center point on the car. This will give you a uniform lift on the entire car and places most (or all) of the vehicle's weight on the rear tires. Constructed from heavy-duty steel box tubing and powder coated for long life and good looks. Set-up and drilling may be required on some lift bar applications. Sold in pairs.
