ACL Race Series are trimetal rod bearings for high-performance engines, designed to withstand higher RPM conditions. Their combination of design, metallurgy and engineering supports consistent bearing operation.
The set includes ACL Race Series rod bearings. The construction is designed to improve bearing retention in the housing, heat transfer and the formation of hydrodynamic oil films.
- High-strength overlay plate with reduced thickness for improved fatigue properties
- Hardened steel backs for improved support of the bearing lining and bearing retention in the housing
- Increased crush for improved bearing retention
- Elimination of flash plating on the back for improved heat transfer and increased grip in the housing
- Increased eccentricity to compensate for bore distortion at high RPM
- Tight, consistent wall tolerances to help maintain consistent clearances
Suitable for: Toyota Land Cruiser II (J9) / J100 (HDJ100) / J70 (HZJ7) / J80 (HDJ80).
Engines: 1HZ, 1HD-FTE, 1HD-T, 1HD-FT (1HD-FTE, 1HD-T, 1H-Z, 1HD-FT). 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.
