The kits include two pistons, pins, and circlips, ready for paired installation on a twin-cylinder engine. Some versions feature a coating designed to reduce friction between the piston and sleeve.

Examples of common applications: Harley Davidson FXSTS 1340 Softail Springer (1999), FXSTB 1340 Night Train (1999), FXST 1340 Softail (1999). Ideal for machining work and engine restoration without compromising fit.
