Question by: Rusty R on Nov 6, 2025, 11:36 AM
got a 2.50 bore cylinder, is this the right size piston cup or am i missin something?
Answer by: Customer Support on Nov 8, 2025, 8:59 AM
Fit comes down to the bore measurement, and this cup is sized for a 2.50 inch bore. The other key dimensions on this one are 0.50 inch height and 1/8 inch thickness, so those need to line up with what your piston setup calls for.
