Spool 4.0 Litre DOHC Barra / XR6 Full Counter Weight 4340 Billet Crankshaft with OEM Stroke

This is a true billet crankshaft machined from Billet 4340 core stock (not a cast forging blank that is final machined).

Each crank is machined from core stock 4340 on a CNC machine, then nitrided and final ground.

Ross Racing Pistons Feature:

  • These Pistons are custom made for Spool and rated at 1800 hp plus by Ross Racing Pistons.
  • Bore Size: 0.010" / +0.25mm
  • Total Seal AP Steel Top Ring, Ductile Napier 2nd Ring, High Tension Oil Rings
  • 4 Valve Pockets
  • 0.220” wall H13 Steel Pins
  • Ceramic Thermal Coated Crown
  • EPC104 Dry Film Coating
  • Horizontal Gas Ports
  • Compression Ratio: 9.0:1
  • Forged 2618
  • Locks

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.

Calico Coated ACL Race Series Bearings

COATED BEARINGS Long term players in the performance engine bearing industry ACL RACE Series Performance Engine Bearings & Calico Coatings have formed a collaboration to offer users an additional option in performance engine building. ACL and Calico are, respectively, technological leaders in the fields of performance engine bearings and performance coatings. Both companies have exemplary reputations for quality, performance & knowledge in their areas of specialization. ACL engine bearings have been coated by Calico for individuals for over 15 years, with proven compatibility and an established track record of excellence in the most exacting and extreme performance applications. ACL and Calico both have rich histories in motorsport, the racetrack is the perfect proving ground. This alliance culminates in the release of ACL offering a range of Calico coated ACL RACE Series Performance Engine Bearings. The coated range is available through all current ACL distributors

DESCRIPTION Our coated bearings combine ACL’s tough RACE Series lining and overlay metallurgy with Calico’s well renowned CT-1 coating. CT-1 is a Dry Film Lubricant coating that helps reduce friction and abrasive wear. It provides intermittent dry lubrication and is not affected by dust or dirt. CT-1 is specifically engineered to withstand the extreme conditions of today’s high performance engines. Professional engine builders enjoy a higher level of confidence with increased embedability, strength and durability

ADVANTAGES Provides intermittent dry lubrication, not affected by dust or dirt, low coefficient of friction. Thin coating to accommodate assembly constraints, chemical resistance, corrosion protection, reduced friction and drag resulting in decreased parasitic losses. • Corrosion Protection • Increased Lubricity • Low Coefficient of Friction • Oil and Fuel Resistant

LOW OIL PRESSURE/OIL STARVATION Theoretically a crankshaft rides on a thin film of oil that protects both the crank and bearing. Real world experience such as cold starts and rough terrain conditions have proven otherwise. CT-1 coated engine bearings provide a dry film lubricant that protects against intermediate oil starvation.
