Internal Engine Parts

Internal parts for your rotary engines from individual rebuild parts like Hard seals, springs, dowel pins and more.

SRRP Solid Dowel Pins  are made exactly the way "PINEAPPLE RACING" dowels were made, using the same super strong proprietary material. They're meticulously machined to Pineapple Racing specifications and diameters. These solid dowel pins help distribute the load evenly across the motor. Keeping the center line true to increase bearing life. Helps prevent against "ping" and cracking your front rear or under plate load. This modification requires no machine work and simply replaces the factory dowel pins. It's a cheaper, easier, and most effective way to strengthen your motor.
