Product Description

Simply the BEST way to protect your sleeves from cracking while eliminating the potential of sinking or leaking sleeves, which can cost thousands in shop labor to repair, even if sleeve repair is free!! The CSS process varies from the typical industry known “blockguard” because it does not rely on the loose tolerance and taper of the factory casting. We actually machine the water passage to a precise dimension to accept our support rings. This means there is 100% contact, along with equal support pressure around the cylinders and from the top of the support ring to the bottom of the support ring. Even the most finely filed/sanded blockguard can not compete with the precision of a 3axis cnc milling machine. The CSS support ring is designed for maximum support while maintain superior cooling characteristics.
