2x Front Billet Lift SpacersInstallation instructionsIMPORTANT: Non-airbag / Auto-ride*Aftermarket Uniball UCA is highly recommended on 2019+ models when front lift is higher than 2.5". The upper ball joint will wear out rapidly with use of stock UCA.Our Pro-Billet series strut spacer lift kits are precision engineered from 6061-T6 aircraft aluminum, then anodized blue for a superior finish. Billet aluminum is a great material for use in suspension applications as it has an immensely high strength to weight ratio along with a superior level of corrosion resistance compared to many other metals on the market. Unlike steel kits that are cut-out and welded together, our Pro-Billet kits are machined from a solid piece and will not bend or warp under even the most stressful conditions.NOTES: An alignment is always recommended after altering the height of your vehicle.
