ACL Race main bearings with Calico CT-1 coating are designed for demanding high-performance engines. The dry film lubricant reduces friction and abrasive wear while providing intermittent dry lubrication, unaffected by dust and dirt.
The coating improves bearing embedability, allowing contaminants to embed in the bearing and helping protect the crankshaft from damage. The set includes ACL Race Series main bearings with Calico CT-1 coating.
- Coating: Calico CT-1 dry film lubricant applied by spray process
- Coating thickness: 0.00025–0.00030 inch or 6–7.5 microns
- Low coefficient of friction with reduced friction and drag
- Corrosion protection and resistance to oil and fuel
- Improved embedability and protection during intermittent oil starvation
Suitable for: Mitsubishi Lancer VIII (CY/A).
Engines: 4B11 (4B11-T). 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.
