Manley Pistons

Platinum Pistons Incremental Sizes

Manlay Performance will manufacture incremental bore sizes of any listed catalog piston with reasonably short lead times. The minimum quantity is eight pieces.

The ordering process is as simple as 1-2-3!
1. Select the catalog part number you wish manufactured with the singular exception of the final size.
2. Tell us the bore size of your block. We will manufacture the exact piston number you have selected except with proper clearance for your stated block dimension.
3. You will be billed by our forging number, not the catalog part number.

Custom Platinum Pistons
Manley Performance inventories the piston forgings listed below to manufacture custom pistons for original equipment engine producers, private label engine part suppliers and volume performance engine builders. We can also produce a forging within ten weeks for any other application a customer may desire.
