Custom Ross Racing Pistons
All of our pistons are forged from 2618 billet bar stock and have been heat treated and aged to a T61 condition (2618-T61). 2618-T61 is the material that is used when fatigue resistance and durability are of prime importance by all premium racing piston manufacturers. This material has less than 1% silicon particulate content. High silicon content pistons (forged from 4032) will not stand up to the most extreme stress placed on many racing pistons. Another advantage of 2618-T61 over the high silicon pistons is the ability to keep its shape under extreme pressure and high RPM’s. “Skirt Shrinking” is not a problem with Ross Racing Pistons.
– Ross Racing Pistons
Hand-in-hand with a top notch piston set such as custom Ross Racing Pistons, is the cylinder surface finish and piston rings. These are often overlooked by ‘assemblers’, yet are vital when it comes to building any high performance engine. We use our Mitutoyo Profilometer to dial in the correct cylinder bore finish depending on the application, and we choose Diamond Honing over regular stones to achieve that perfect finish. We have Ross Racing Pistons in our ’66 Nova built for Drag and Drive events.
Total Seal AP Steel Gapless and Gas-ported Piston Rings provide excellent ring seal and are our choice of pistons for all our builds, from a 2180cc aircooled VW motor through to a 4000hp Billet V8.
