CB265-6002 – S65 4.2L Rebuild Kit
This kit includes replacement of the OEM rod bearings with high performance bearings, CarBahn Autoworks valve springs, 2mm over-sized CarBahn Autoworks forged pistons and head gaskets.
CarBahn high performance valve springs are sold separately and provide significant improvements in durability.
Head gaskets come in 3 thicknesses (.027”- .036”- .040”) depending on the deck height.
Connecting rod bearing and valve springs are common failure items on S65 and S85 engines. In response, CarBahn Autoworks has developed improved bearings and valve springs.
