Pins and Hastings chromoly rings are included with these pistons.
The pistons are designed to use pins that are 2.500" long x 0.866" diameter (included are 0.125" thick wall) and use Spiralox. Should you want to get alternate pins - we offer Tool Steel Pins and ubersrtong H13 Pins.
NOTE: We HIGHLY recommend that you have your pistons PRIOR to boring your block, so your machine shop can bore to the proper clearances for the pistons. The listed piston sizes are approximate, and as there are different tolerance requirements between different piston manufacturers and even exact size variations between piston production runs, you should never bore you block without having the pistons that are going in the block so the machine shop can bore to match the pistons and their specific clearance requirements. 3SX is not responsible for pistons not matching a bore - take that up with your machine shop that did the bore.
NOTE: These are special order pistons with a lead time of about 5 weeks. Please consider this lead time when ordering.
