These kits allow you to fit a 1/2" eyelet shock (Fox, Rockshox, DVO etc.) on a bike originally fitted with a Trunnion shock.   Available in 40mm, 50mm and 54mm widths and threaded to accept 10mm Trunnion Bolts.. Each kit contains 2 x spacers, 1 x low friction poly bushing and 1 x stainless steel mounting hardware..   Please Note: You absolutely need a DU bush tool to fit these, don’t attempt to press them in with a socket, you will split the poly bush – buy a tool here
