Message	Sup guys, Just wanted to give everyone a heads up on an issue I had today. I am building a short block for a client utilizing some Wiseco 87.5MM shelf pistons (8750XX) rings. Upon opening the rings up and separating into each pile I noticed that a couple were smaller in size. Be sure you all are checking your ring packages before moving to machining/ring gap/assembly. Verify the rings fit the pistons/same as other rings in kit before you move any further. Wiseco will not warranty/swap out for the correct size if you've modified the rings in any way (i.e gap/file them) Im am now sitting on my hands till Wiseco can send me out a proper set of rings. I just want ppl to be sure they are inspecting their parts before they move any further. I caught this before I did any ring profiling. Images below.... Top rings are correct ring size...lower rings are the incorrect rings supplied in the piston kit. Pics of the N50 (correct size rings) Incorrect ring. Notice no profile dimension is laser etched on top surface. Ep Racing | Create Your Badge
