ACL Race main bearings with Calico CT-1 coating use a dry film lubricant that helps reduce friction and abrasive wear. The coating is engineered for the demanding conditions of high-performance engines.
CT-1 improves embedability, allowing debris contaminants to embed in the bearing and helping avoid damage to the crank. The set is designed to provide protection during intermittent oil starvation and offers resistance to oil and fuel.
- Calico CT-1 dry film lubricant applied by spray process
- Intermittent dry lubrication and low coefficient of friction
- Corrosion protection and resistance to oil and fuel
- Increased embedability for debris contaminants
- Thin coating to accommodate assembly constraints
Suitable for: Nissan Skyline I (R32) / II (R34) / III (R33).
Engines: RB26DETT. Please check your vehicle’s engine code (registration document or VIN) before ordering; if in doubt, contact us and we will check for you.
Sizes
STD is the standard size for an unground crankshaft. Undersizes (−0.25 mm, −0.50 mm …) are for a reground crank, and “+0.025 mm clearance” (X) is for highly stressed engines. Your machine shop chooses the size after measuring.
