Shown photos are no longer representative of true product.

Applicable to M156’s with any stage superchargers and/or nitrous pushing higher torque. Highly overbuilt for stock units. Storage friendly due to its corrosion resistant surface. For Stock or lightly tuned M156 please refer to Stage I+ Lockplates.

Includes 63 Motorsports M156 two intake, two exhaust replacement lockplates, set of pins w/ guaranteed fitment, and springs to complete the set in rebuilding the camshaft adjusters in an M156/M159.

After several iterations, logistical processes, and testing, we increased the strength of the alloy and lowered the Coefficient of Friction using heat and diffuse layer treatments. Stage II further preserves your M156 with its inherent anti-corrosion layer that is permanently bonded to the alloy. No virgin (uncoated untreated) quench and tempered steel alloy variant will out-perform the Stage II+’s slick surface.
