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 torque specifications for the ARP2000 bolts in the Spool Drag Pro I Beam conrods?
For the ARP2000 7/16 bolts included in the Spool Drag Pro I Beam conrods, the recommended torque specification is around 75 ft-lb when using ARP Ultra-Torque lubricant. Always refer to ARP's latest instructions for the most accurate guidance.
What machining is required for the Ross Racing forged pistons included in this kit?
The Ross Racing forged pistons require precise bore clearance and ring gap settings, which depend on your specific engine build. Ensure that the bore is honed to the correct size and that the ring gaps are set according to the intended use and power levels.
Can I use L19 bolts with the Spool Drag Pro I Beam conrods?
Yes, L19 bolts are available as an upgrade for the Spool Drag Pro I Beam conrods. If you choose to use L19 bolts, remember to tighten them by measuring stretch rather than using torque values.
What is the maximum power rating for the Ross Racing pistons in this kit?
The Ross Racing pistons included in this kit are rated for 900-1000hp. However, actual performance and reliability will depend on factors such as machining, clearances, tuning, fuel quality, and boost levels.
Do I need to balance the crankshaft with the full rotating assembly when using this kit?
Yes, it is essential to balance the crankshaft with the full rotating assembly when using the Spool Drag Pro I Beam conrods and Ross Racing pistons. This ensures optimal performance and reliability at high RPMs.
