Ross Racing Custom Piston Set, Any Bore, Any Stroke, Flat, Dish, or Dome, Set

Description


High performance pistons from any manufacturer are only as good as their designer. BP has spent years of dyno and track testing to develop our current designs. BP stocks several popular pistons by ROSS but we can design a custom piston for any application to fit your needs. Allow approximately three to four weeks for custom orders. Expedited Production/Shipping is available from Ross. Guaranteed to ship in 5 business days.

These custom LS pistons are designed by Butler Performance and machined by Ross with state of the art CNC machines. Using the T61 Forgings allows us to get a lighter piston with more strength than a 4030 Forging. Ross also offers a ceramic heat barrier top coating and a antifriction skirt coting. These pistons can also be run at tighter piston to wall clearance so they are great for performance street applications as well as all-out racing.


All ROSS Racing Pistons (since 1985) have been 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 or MS75) will not stand up to the most extreme stress placed on many racing pistons. If a crack starts to form in a high silicon piston it will continue until the piston experiences a catastrophic failure. Simply stated, adding sand to the aluminum only makes it more brittle. In the rare instance of a 2618-T61 piston cracking, the crack will continue to an area where the stress is not as great and will then stop. 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.

Custom pistons are not returnable.
