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.

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 are the benefits of using Calico Coated ACL Race Series Conrod Bearings in an RB30 engine?
The Calico Coated ACL Race Series Conrod Bearings provide enhanced durability and reduced friction due to the CT-1 dry film lubricant coating. This coating helps to protect against abrasive wear and offers intermittent dry lubrication, making it ideal for high-performance applications where oil starvation may occur.
Do I need to modify my RB30 engine for these bearings?
Generally, these bearings are designed to fit standard RB30 conrod dimensions. However, it's essential to check the fitment and ensure proper clearance during assembly. Any machining or modifications should be done according to the engine builder's specifications.
How do I ensure proper lubrication with these bearings in my RB30?
While the CT-1 coating provides additional protection, it's crucial to maintain proper oil pressure and ensure the engine is adequately lubricated at all times. Regular oil changes and using high-quality oil are recommended to maximise the performance and longevity of the bearings.
What is the expected lifespan of Calico Coated ACL Race Series Bearings in a race application?
The lifespan of these bearings can vary significantly based on engine tuning, oil quality, and operating conditions. In a well-built RB30 engine with proper maintenance, they can withstand extreme conditions, but regular inspection is necessary to monitor wear and ensure reliability.
Are there any specific installation tips for these bearings?
When installing the Calico Coated ACL Race Series Bearings, ensure that the bearing surfaces are clean and free of debris. Apply a thin layer of engine oil before installation to aid in initial lubrication. Follow the manufacturer's guidelines for torque specifications and clearances to avoid premature failure.
