Butler Performance Engine & Rotating Assembly Combinations

NEW LOWER PRICES ON MANY OF OUR MOST POPULAR ASSEMBLIES

 Our longrod assemblies offer the ultimate in durability and performance!

These assemblies utilize the lightest, strongest pistons and pin design available. We use only the highest quality ROSS Pistons in all of our long rod assemblies, not the cheaper pistons that many retailers sell at a similar price. Our ROSS pistons have the best weight to strength ratio on the market, and use our own proven Butler Performance designs. Nitrous Safe.

These Butler Performance rotating long rod assemblies come standard with H-beam 4340 forged steel rods from Eagle or SCAT (unless otherwise noted), two of the best names in the business! Bolt upgrades available if needed.
Pre-Assembly Tip Page

All assemblies are internally balanced and require a neutral balanced flexplate or flywheel and harmonic balancer. All our assemblies come standard with Total Seal Classic rings. (See ring descriptions here). Our assemblies can be upgraded with the following:
