Build a high quality engine with these “stroker” pistons & cylinders from Mahle. Each set includes pistons, rings, piston pins, clips and cylinders. Build up to a 2330cc size with this set (84 stroke.). Machine work to the engine case and heads is required for installation. You may need custom cylinder spacers for longer strokes and long rods. Each set of pistons is matched for weight, so there’s no need to custom balance. Top quality!
