Colt Cams M57 Reground Camshafts
Both intake and exhaust camshafts are reground by Colt Cams for performance oriented M57 applications. Changes to the cams are .020" lift increase and 20 degree increase in open duration which is then multiplied by rocker ratio. Valve opening/closing timings are also altered to better suit a performance application. Dyno testing will be completed soon!
We have 2 sets of floating cores to try and keep downtime to a minimum for time sensitive jobs. A fully refundable $500 core charge will apply if you choose that option. Once your good condition cams are received by Colt, the core charge will be refunded.
