All of 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.

What information do I need to match these pistons to my engine?
You need the engine code, bore size, stroke, rod length, pin diameter and target compression ratio. These determine the correct piston compression height and crown design.
How should ring gaps be set for these pistons?
Ring gaps must be set by your engine builder based on fuel type, boost level and the intended rpm range. Forced-induction engines usually require larger gaps.
Are forged pistons suitable for street engines?
Yes. Forged pistons handle detonation and high cylinder pressure better than cast units. Your builder should set the piston-to-bore clearance to suit your application.
What is the recommended compression ratio for the RB26DETT Ross Racing forged pistons?
The recommended compression ratio for the RB26DETT Ross Racing forged pistons is 9.0:1. This ratio is designed to optimise performance while maintaining reliability under high power conditions.
What bore sizes are available for these pistons?
The RB26DETT Ross Racing forged pistons are available in bore sizes of 86.5mm and 87mm. It's crucial to ensure proper fitment based on your engine's specifications.
What is the maximum power rating for these pistons?
These pistons are rated by Ross Racing for use in applications producing between 900 to 1000 horsepower. However, actual performance will depend on factors such as tuning, fuel quality, and boost levels.
What material are these pistons made from?
The RB26DETT Ross Racing forged pistons are made from 2618-T61 forged aluminium. This material offers superior fatigue resistance and durability, making it suitable for high-performance applications.
What type of oil do you recommend for breaking in a new engine with these pistons?
For breaking in a new engine fitted with these pistons, we recommend using Joe Gibbs Break in Oil. This oil helps ensure proper seating of the rings and overall engine longevity.
