Ross Forged Piston Set Flat Top 87mm Bore L28 280Z 280ZX

New set of Ross Racing forged flat top pistons for 87mm bore.  Set of 6 pistons with pins and rings.   True flat top for a higher compression than most stock and aftermarket pistons.  

These pistons use a thinner ring set than stock and with that reduced friction, ring manufacturers claim about 10HP advantage over stock.  

We estimate a 15-30HP gain with these pistons over stock as a result of the reduced friction rings and added compression.
