Replacement Pin and Circlips for our 52mm TBW0190 and TBW0365 pistons. If you aren’t sure what piston you have, please send us a message and mention what year model engine the piston was in and if it was on of the TB stroker cranks used in the engine – the more details on the type of engine and modifications such as race head being used or not etc will help us determine which piston you have.
