HYP/COATED PISTON 5.8L FORD

MIA's Description

The Silvolite 3166HC.030 is a set of hypereutectic aluminum pistons designed with a dish-style top and no valve reliefs. These pistons feature a 4.030 in. bore and come with a stock engine stroke type. The set includes wrist pins, but piston rings and retainers are sold separately.

They also offer improved groove wear and resistance to crown cracking in high-temperature areas. The pistons have reinforced top lands and diamond-finished skirts.
