If you are after more flex in your vehicles rear end, then Extended Shackles are an easy way to achieve it. Basically the extended shackle creates a greater sweeping arc of the shackle which in turn provides for more wheel travel and a nicer ride. Roadsafe Extended Shackles are engineered to the highest standard, with factory size Greasable Pins (to allow installation of factory bushings) and 50mm extended plates. All Roadsafe extended shackles incorporate a stepped bolt design, ensuring that the shackles cannot be overtightened, resulting in deformation of the bushings. Giving 50mm more length than the factory shackle you will also see a lift of between 25-30mm. Solid Axle - RR Extended Shackles
