The Gasbox full frames are the highest quality and best engineered available. This frame allows direct bolt-in fitment for 2004-2022 Harley-Davidson Sportster engines (except Revolution Max engines), which are rubber mounted . Frame construction is thick-walled 1" diameter tubing with 1-1/2” backbone and seat post, completely TIG welded. The rigid rear section has approximately 4" of stretch and is set up to have 2" of drop as compared to a stock frame. The steering neck is set at 32° for a perfect stance.
The engine is rigid-mounted in the frame, eliminating the rubber bushes. With a rigid rear section as found on this frame, the belt drive must be converted to a chain drive ( Shop for a chain conversion kit here ).
