Ross Racing Pistons:
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.
Note: We recommend Joe Gibbs Break in Oil for all new engines.

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 Spool 1UZ-FE conrods and Ross Racing pistons?
For the Spool 1UZ-FE conrods, ensure that big-end and small-end clearances are checked and honed as necessary to achieve proper fitment. The Ross Racing pistons require specific bore clearances, typically around 0.0015" to 0.0025" depending on the application. Always consult with your engine builder for precise specifications.
What is the compression ratio of the Ross Racing pistons included in this kit?
The Ross Racing pistons in the Spool 1UZ-FE kit have a compression ratio of 9.0:1. This ratio is suitable for a range of performance applications, but ensure that your engine's tuning and fuel quality are compatible for optimal performance.
What type of fasteners are used in the Spool 1UZ-FE conrods?
The Spool 1UZ-FE conrods come standard with ARP2000 fasteners. For higher performance applications, you can upgrade to L19 fasteners, which provide greater strength and reliability under high-stress conditions.
Do I need to perform any specific machining on the conrods and pistons?
Yes, the conrods may require honing of the big-end and small-end to ensure proper fitment on the crankshaft and pistons. The Ross Racing pistons also require careful attention to bore clearance and ring gaps, which should be set according to your engine's specific requirements.
What material are the Ross Racing pistons made from?
The Ross Racing pistons are forged from 2618 billet bar stock, which is known for its high fatigue resistance and durability. They are heat treated and aged to a T61 condition, making them suitable for high-performance applications.
