Wishbone locators are the most popular housing locator device with pro chassis builders and racers for high horsepower applications. A wishbone locator will positively locate the rear end housing and do so without binding. With little to no deflection/bind throughout the range of motion, wishbones will not rob you of power, movement or E.T.'s. Chassis Engineering offers two differnt versions to select from. Need help deciding which one will be the most appropriate for your application?...Give us a call, we are more than happy to help.
