Can't get enough power from your engine with stock and clone parts? We have the big bore and stroker parts you need to push your small engine to the limit. To install these big bore pistons and rings, you will need to bore out the stock block. Piston sleeves add strength back to bored blocks. We offer pre-sleeved blocks, cutting down on your work at home. Big bore head gaskets create a tight seal around machined blocks and heads.

Stroker kits increase the distance the piston travels on each rotation. This adds displacement, increasing torque. These kits include a new crankshaft, piston, rod, rings and hardware. The crankshaft must be balanced before use. You can do this yourself, or we can do it for you for an additional fee.
