Our SPL Parts Eccentric Lockout (EL) kit eliminate the stock eccentric bolts to keep your rear alignment where you set it. You must have adjustable control arms in order to adjust toe after eliminating the stock eccentric bolts. Our lockout plates are CNC machined from 6061-T6 Aluminum and supplied with zinc plated grade 10.9 bolts and lock nuts for absolutely zero-slip. This kit includes washers and bolts for both camber and toe arms. Sold as a complete kit for one car.Made in the USA.
