Modified 1275 A-plus Mini Crankshafts

Due to popular demand, MED re-worked crankshafts are back, for 1275 engines with A-plus 1.750" big ends and 2.000" diameter main bearing journals.

These are based on brand new Rover CAM6232 crankshafts, modified for high performance road and trackday engines.

The crankshafts are CNC-machined to improve counterbalance and also reduce overall weight. More specifically, we've re-profiled the web around the big end journal area, where this has the most effect, as can be seen from these work-in-progress pics...

Once machined and balanced, we have a ni-temper treatment applied before a specialist polish and quench technique to improve journal durability.

Spec:

- Std/std journal sizes

- Heat treated journals

- Cross-drilled mains

- Wedged to improve counterbalance and reduce weight

- Balanced dynamically to within 1g

These are available only while stocks last, as we only have a limited quantity of NOS crankshafts, Rover part number CAM6232.
