The mountune steel con rod upgrade offers owners of both Mk8 Fiesta ST and Puma ST a credible option for safely increasing their engine's ability to run high-power and high-torque outputs, as well as to utilise increased engine revs.

Designed to work in harmony with the mountune forged piston upgrade, or any other forged piston that uses a 21mm gudgeon pin and compatible crown design.

Supplied with ARP rod bolts for ultimately reliability and new big end bearings (not available as a consumable item from Ford).

Please note some modification to the block will be required to allow clearance for the stronger rod.
