Ross Racing Pistons:
ROSS has one of the most complete selections of general purpose and specific use forgings in the entire custom piston industry. We make pistons from 2.283" (58 mm) through 6.190" (157.2 mm) diameter for hollow dome, flat top and dish top applications.
As can be seen in the photo, the lack of external features on the ROSS forging allows us complete freedom in machining special features for your pistons.
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.

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 compression ratio do the Ross CA18DET pistons provide?
The Ross CA18DET pistons have a compression ratio of 9.0:1, which is suitable for a balance of performance and reliability in turbocharged applications.
What bore sizes are available for the Ross CA18DET pistons?
These pistons are available in two bore sizes: 83.5mm and 84mm, allowing for flexibility in engine build specifications.
What material are the Ross CA18DET pistons made from?
The Ross CA18DET pistons are forged from 2618 billet bar stock and heat treated to a T61 condition, providing excellent fatigue resistance and durability under high-stress conditions.
Do the Ross CA18DET pistons come with additional components?
Yes, the pistons come complete with rings, gudgeon pins, and pin locks, ensuring you have everything needed for installation.
What are the advantages of using 2618-T61 material for these pistons?
The 2618-T61 material offers superior durability and resistance to deformation under high pressure and RPM, reducing the risk of catastrophic failure compared to higher silicon content pistons.
