Seven built, L60 Mk 1 or L60 Mk 4, initial vehicles had internal exhaust silencers, short hull, small diameter road wheels. In an attempt at reducing the overall height of the vehicle the original design used road wheels of a smaller diameter which gave insufficient ground clearance. They were later replaced with Centurion road wheels of a larger diameter and by careful re-positioning of their mountings along with adjustment of the idler and final drive mountings resulted in a vehicle height only higher than with the original smaller wheels.
