Engine pistons & ring sets
Piston and ring sets for diesel and petrol rebuilds — from OEM-equivalent replacements to performance forged pistons — in standard and oversizes to match a rebored block.
Complete your rebuild
Match your pistons with the rest of the bottom end.
Standard, oversize & forged
We stock MAHLE, JCC, Yenmak, ACL and more. Most sets include rings to suit; oversizes (020, 040 and up) match a machined bore. Tell us your engine and bore size and we’ll confirm the right set.
Piston FAQs
What oversize piston do I need?
Match the oversize to your rebored block (for example +0.020"). If the block hasn’t been measured yet, your machinist will spec it — or send us the bore size.
Cast vs forged pistons — which should I choose?
Cast/hypereutectic pistons suit stock-to-mild rebuilds; forged pistons handle the heat and load of high-boost and high-power builds. We can advise based on your goals.
Do the rings come with the pistons?
Most of our piston sets include matched rings. If you need rings only or a specific ring pack, just ask.
