NOTES: Wiseco 3051 Series piston for Force engines: Many of the Force L-Drive engines were with a piston which has two large holes machined in the piston skirt. Force produces the L-Drive motor with these holes to reduce piston weight. Wiseco was able to match the piston weight without the holes, which, in turn produces a stronger piston. Replacement Wiseco rings can be ordered as well. Wiseco ring numbers can be obtained by taking the bore size and adding a KD after it. Example: A 3067PS piston has a bore diameter of 3.187". The Wiseco ring set for it would be a 31 87KD. |
