ACL Race rod bearings for Mitsubishi 4G93 / 4G92 / 4G91

ACL Race are tri-metal rod bearings designed for higher RPM conditions. The combination of construction, metallurgy and engineering improves fatigue resistance and bearing retention in the housing.

The set includes rod bearings with hardened steel backs and features that support consistent clearances 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
• Increased crush and eccentricity for improved retention and compensation for bore distortion at high RPM
• Elimination of flash plating on the back for improved heat transfer and grip in the housing
• Tight, consistent wall tolerances to help maintain consistent clearances

Suitable for: Mitsubishi Carisma I (DA), Mitsubishi Colt IV (CA) / V (CJ/CP), Mitsubishi Galant VII (E5/E7/E8), Mitsubishi Lancer IV (C6/C7) / V (CB/CD) / VI (CJ/CP), Mitsubishi Pajero Pinin I, Mitsubishi Pajero Sport I (K90), Mitsubishi Space Runner I (N1/N2), Mitsubishi Space Star I (DG/A), Mitsubishi Space Wagon II (N30) / III (N50), Proton Persona 400 I (C9C/C9S), Proton Persona I (C9M), Proton Satria I (C9M), Proton Wira I (C9L).

Engines: 4G93, 4G92, 4G91 (4G93, 4G92, 4G91, 4G93-T, 4G92MIVEC). 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.
