Wossner pistons are made from dedicated forgings produced in-house to give you a light weight piston with superior strength and optimal design.
Being the multivalve piston technology leader, the line features specially designed valve pockets, complex dome and crown shapes, the steel nitride/napier xx rings and optimized skirt profiles.
Most OEM pistons have pin offset to keep the piston quiet. Only Wiseco does this with forged pistons.
Complete with rings, wristpins & locks, and specification sheets.
