Triumph Hepolite Unit 500 piston and ring kit

This Hepolite kit includes everything you need to take your unit 500 cylinder to the next size. Pistons, wrist pins, circlips, and the most modern and the highest quality ring set available today. These Triumph pistons are a replica of the pistons originally fitted as OEM for the 1967 -1974 "non squish band" head Daytona 500. Having sold this piston set for years, and using them in our builds, these are an excellent choice for any street or engine, pre unit or unit construction. These pistons are manufactured by JCC and the rings are exclusively made in England for Hepolite. This premium ring set includes a two piece oil control ring with a coil spring. This modern ring design is far superior than one piece designs, and is easier to install than 3 piece oil rings.  This set is for 500cc engines (with the "non squish band" head) with a 2.7165" standard bore ( 69mm ), available in standard, .020", .040", and .060" oversizes only.
