FAQ
Are these truly drop-in?They are stock-style replacements supplied with rings/pins/clips. Proper machining for +.020" and precise measurements are required for correct clearances.
How many ring packs do I need?These pistons come with rings. If you are sourcing extra rings separately, you need six individual ring packs—one per cylinder—at the correct oversize.
Do I need upgraded fasteners?Not required for a basic stock rebuild, but main or head studs are recommended for heavy towing or higher cylinder pressures.
