S65 4.2L Rebuild Kit

$4,999.00

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. If your engine has between 75,000 and 100,000 miles on it, we recommend this refresh kit which goes an extra step further over our repair kit.

This kit includes high performance rod bearings and CARBAHN Autoworks valve springs, plus 2mm-over-sized CARBAHN Autoworks forged pistons.

The increase in bore raises the displacement to 4164cc, increasing power by 18HP to 432HP.
