Land Rover Series 1, 2, 2A 3 Polyurethane Bush Kit Yellow This listing is for a comprehensive set of polyurethane suspension bushes, suitable for later Series 1s with the wider 2.5" leaf springs, Series 2, 2A and 88" Series 3s. These are made using the latest Vulkollan™ technology, producing high quality and long lasting bushes. They are machines to exact tolerances once cast to produce the highest finish available. Polyurethane bushes give similar ride characteristics to the standard rubber bushes, but they offer improvised articulation, vibration damping and they last longer. These bushes are also much easier to fit, as they do not require presses unlike standard bushes. Many of the bushes are supplied in 2 halves with a metal collar that slides into the centre. This kit.
