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 is included in a typical Spool engine kit?
Kits usually include pistons, rings, rods, bearings and related hardware depending on the engine family. Check the listing for exact inclusions.
Do I still need machining with a full engine kit?
Yes. The block must be honed and all clearances checked and set by your builder. Assembly should only occur after full measurement and verification.
What are the recommended clearances for the Ross Racing forged pistons in this rebuild kit?
The recommended bore clearance for the Ross Racing forged pistons is typically around 0.0015" to 0.0020". However, it's essential to verify this with your specific engine setup, as clearances can vary based on the builder's preferences and the intended use of the engine.
What is the maximum power rating for the components in this rebuild kit?
The Ross Racing forged pistons in this kit are rated for 900-1000hp. However, actual performance will depend on factors such as tuning, fuel quality, boost levels, and overall engine assembly. Reliability is contingent on proper machining and clearances.
Do I need to upgrade the ARP2000 bolts in the Spool conrods for high horsepower applications?
While the ARP2000 bolts are suitable for many applications, if you plan to push towards the upper limits of the power rating, consider upgrading to L19 bolts for added strength and reliability. Always follow ARP's latest installation instructions for torque or stretch specifications.
What type of head gasket is included in this rebuild kit and what surface finish is required?
The kit includes a Cometic MLS head gasket, which requires a surface finish of 50 RA or better for optimal sealing. Ensure that both the cylinder head and block surfaces are machined to meet this specification.
Are there any specific break-in procedures recommended for this rebuild kit?
Yes, it is recommended to use Joe Gibbs Break-in Oil for all new engines built with this kit. Follow a proper break-in procedure, which typically includes varying engine RPMs and avoiding prolonged idling to ensure proper seating of the piston rings and bearings.
