Parts Guide

Please select the part number you require from the drop down menu by utilising our vehicle fitment guide and parts guide.

Notes:

• The small end of the conrod needs to be resized to suit the gudgeon pin except for the kit with H-beam conrods and 0.040" oversize forged pistons.
• For flexibility, the assembly is not balanced so it can suit either Ecotec L36 or L67 Supercharged 3.8L engines with your own harmonic balancer and flywheel/flexplate. 
• The conrods come semi-finished so they can be honed and blueprinted to match your specific engine as well.
• Engine block will require machining to support the larger stroke crank.
