These are designed to adjust your rear ride height and track width when used in conjunction with the Toe Adjustment Links. You get over 3″ of ride height adjustment and 1.5″ of adjustment on the bushing end. These are perfect for getting your wheel fitment just right. They include high quality Energy Suspension polyurethane bushings, spring isolators, and FK Heim joints. They will also stand up to the abuse that larger rear swaybars put on your stock control arms, sometimes causing the non SVT ones to break! Kits are custom made to order at this time. Lead time varies depending on production.
