High Quality squeeze-cast pistons manufactured by AE.


Mini Mania stocks these pistons in conventional 1275 oversizes (+.020, +.040, +.060) in both flat-top (C-AJJ3382/size) or dish (C-AJJ3378/size) configuration, and in dished 73.5mm "big bore" configuration for 1380s (C-STR310). These pistons are bulletproof!

The wrist pin to piston crown measurement on the C-AJJ3382 piston is 38mm.

Desperately inconsistent supplies for protracted periods of performance Mini pistons caused Mini Spares Centre to develop the 'MEGA' piston range.

Recruiting the AE Hepolite Group for their unquestionable and renowned design and manufacturing expertise, the goal was to produce the most robust piston possible given reasonable cost and weight limits. Applying current technological advances incorporating their very latest hi-spec AE109TF lightweight alloy and special double heat treatments, the result is an extremely durable piston that will withstand greater cylinder pressures at higher rpm than any other currently available.

To simplify the range, material has been concentrated around various problem areas - the ring lands and crown - providing one crown height which is 1.2mm thicker than other leading manufactures. This ensures sufficient material in critical areas to allow machining where long stroke cranks or longer con rods are used. This design guards against premature damage from poor/low quality modern fuels with the rings re-sited to minimise detonation damage in high compression engines. The ring dimensions are compatible, and therefore interchangeable, with the Omega Mini piston range. Full circle skirts are used for maximum piston and ring stability. They also feature a specifically designed ridged finish on the side of the piston walls which helps retain oil, to protect against scuffing and galling at start up and cold running. A tapered gudgeon pin is employed to maximise stiffness against its lightweight.

Height from center of wrist pin to crown of piston is 37.84mm
