FAQ
Are these a direct drop-in?They're stock bore with rings/pins/clips included, but you still need machine-shop checks for clearance and ring gaps to meet spec.
What's the benefit of the “marine big bowl?The larger bowl can improve airflow and mixture motion, helping with cleaner combustion and more even heat loading in performance/tow builds.
Do I need head studs with these pistons?For stock power, OEM bolts are acceptable. For added boost, towing, or tuning, head studs are strongly recommended for clamping margin.
Can I order oversize pistons later?Yes-see the .020"/.040" links above if your cylinders require an overbore after inspection.
