FAQ
Do these pistons come with rings and pins?Yes. Each set includes matched rings, wrist pins, and retaining clips for a complete install.
Why choose the Marine “big-bowl design?The larger bowl improves mixture control and can help reduce EGTs on tow/work builds while supporting added fuel and boost.
Can I install these without boring the block?No. .020" oversize pistons require a professional overbore/hone to specification.
What fasteners should I use on a performance 12-valve?Head studs (e.g., ARP 247-4203) are recommended for boosted applications; main studs are a smart upgrade on higher-power builds.
