Description -

Long Rod and Flat-Top Piston Combo
Economical kit that produces significantly more HP than the stock rod and piston. Kit uses special long length rod and custom flat-top piston so that it fits a stock bore in a GX390 without any machining or boring.
Includes piston, rod, rings, bearing, and wrist pin.

Piston: Cast Flat-Top Cut -.100"
Rod: Billet 4.510" Rod
Bearing: Tri-Metal

Rings: 3 Piece Moly
Wrist pin: OEM Honda HD

*Notes: Piston does not have valve reliefs. Care must be taken when selecting camshaft.
On used blocks, a light hone may be needed for proper ring seat, and bore must be straight. Slight grinding on the crank counterweight or on camshaft may be needed to clear rod. You must have at least .020 between head and piston.
