Ross Racing 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 is the recommended compression ratio for the Ross TB48 pistons?
The Ross Racing forged pistons for the Nissan TB48 have a compression ratio of 9.0:1. This is suitable for applications where a balance of power and reliability is desired.
What bore size do the Ross TB48 pistons accommodate?
These pistons are designed for a bore size of +0.5mm over the standard dimensions of the Nissan TB48 engine. Ensure your engine block is machined to the correct specifications for proper fitment.
What materials are used in the construction of the Ross TB48 pistons?
The Ross TB48 pistons are forged from 2618 billet bar stock, which is known for its high fatigue resistance and durability. They are heat treated to a T61 condition, making them suitable for high-performance applications.
Do the Ross TB48 pistons come with all necessary components for installation?
Yes, the Ross TB48 pistons come complete with rings, gudgeon pins, and pin locks, providing everything needed for installation in your engine.
What advantages do 2618-T61 pistons have over high silicon content pistons?
2618-T61 pistons, like the Ross TB48, offer superior durability and resistance to cracking under extreme stress compared to high silicon content pistons. They maintain their shape better under high pressure and RPM, reducing the risk of catastrophic failure.
