Caliper Piston set.

This is a large 54mm caliper piston Front for a Jaguar E-Type 1968 to 1971, TR3 to TR6 and GT6 using the 16P type caliper. They also fit Austin Healey BJ8 from 26705 and MGC. Two are needed per caliper. The pistons are Plasma Nitrided which will give you the life of Stainless at half the price. The Nitriding becomes a part of the metal and will not flake off or separate, you can't buy a harder caliper piston.
