Childs & Albert CARS-31ZX-4.130 Clearance - D-Moly Zero Gap Dykes Ring Set 4.130 Bore

With literally thousands of engines utilizing Childs & Albert's advanced one-piece design, it has gained recognition as the only true one-piece zero leak ring. The one-piece step gap design of the C&A ZGTF Piston Ring eliminates forever any possible end gap alignment leakage common to competitors two piece ring design. The ZGTF Ring made from ductile iron incorporates a two degree outside taper which acts like a precision squeegee, wiping the cylinder wall clean of excess oil, eliminating possible combustion chamber contamination which can lead to detonation. Cylinder friction is reduced while all conformability is increased. You can now see why Childs & Albert is still, without a doubt, your high performance ring leader.
