Genuine Honda Full Thread LSD Bolts K20
These bolts are required most often when fitting a helical Mfactory LSD to a K20 Gearbox. Some early K20 Gearboxes have full threaded LSD Bolts but most do not. If these are not used the Shouldered bolt found in most K20 Gearboxes bottom out before the Crown Wheel is tight on the LSD.
10 are required to replace all when fitting a LSD.
