Precision Fit: Designed for 4.000 inch cylinder bore, Fits 4.00" Bore 6.0L LS2 LQ4 LQ9 L76 L77 L96 L98 and more 4.00" bore engines
Reverse chamfer design: The reverse chamfer at the bottom matches the chamfer of the cylinder body to achieve automatic centering, reduce deviation, optimize the passability of the oil ring, reduce the risk of sticking, and improve installation efficiency and smoothness
Durable and Lightweight Material: Made of 6061 aluminum alloy, it is light and strong, with mirror polished surface to reduce friction and scratches, improve durability and feel
Fine Details: Smooth edges without burrs effectively protect the piston ring and cylinder body; the non-slip design on the outside is easy to hold.
No Auxiliary Tools Required: The conical compression structure design allows easy installation of the piston without a clamp, making it easy to operate and suitable for all types of maintenance scenarios
