Button Pistons | What Do YOU Know About Wrist Pin Retainers [TECH TALK]

Button retainers are not new technology, but they are also not something that has been seen that often, particularly in the sport compact market due to the perceived possibility of bore damage and increased weight.

As CNC billet technology improves a lot of designs that were flawed with the previously available manufacturing techniques can be revisited and improved upon and Dan from Diamond Pistons explains to Andre what they have done in this respect with their button retainer designs.

Discussed is the fact that it is not just poor installation that can cause failure with some of the alternatives and how a button retainer design avoids this along with some of the design advantages for the ring packs with this option for high boost/power-adder race engines including the advantages of thicker piston rings when it comes to heat dissipation.
