Frames are EXCLUDED from the free shipping over $79.95 special. - For 1957-1985 Harley-Davidson Sportster engines
- Includes MSO (Manufacturer's Statement of Origin)
- Highest quality available with perfect fit and finish
- Made in Cleveland, Ohio, USA. The Gasbox full frames are the highest quality and best engineered available. This frame allows direct bolt-in fitment for 1957-1981 Harley Ironhead Sportster engines. It will also accept 1982-1985 Ironhead Sportster engines, though the rear motor mount on these years needs unbolted and replaced with the
earlier rear motor mount, Harley OEM # 16203-67, so it will directly bolt in place. All 1 inch tubing, completely TIG welded and made in Cleveland, Ohio, USA. Each frame will receive an MSO (Manufacturer's Statement of Origin) sent separately in the mail directly from The Gasbox. This will have the frame's individual serial number (located on a raised pad welded to the neck of the frame) as well as the purchaser's information. This is needed in most places when titling a custom motorcycle, Unlike other custom frames, the Gasbox Ironhead frame uses stock motor mounts all around, with the engine cradled low in the frame rails just like a stock bike. This looks much cleaner and keeps the finished chopper looking lean and handing better with a lower center of gravity. This frame also accepts the stock Sportster kickstand. The neck is a 34 degree rake and set up for a 1 inch stem. This stem size is very common and is found on narrow glide front ends on Sportsters 1982 and later, and on Harley Big Twin front ends, including narrow glide, wide glide, OEM and most aftermarket springer front ends. The neck is in the stock location, this frame has no 'up' or 'out' dimension to the neck, and utilizes 1" stem timken style neck cups. The
rigid rear hardtail section has approximately 4 inches of stretch and is set up to have 2 inches of drop. This means that with a front end and wheels on the bike the lower frame rails sit 2 inches closer to the ground than stock for that perfect stance. The axle plates are set up for a standard 3/4 inch rear axle and accepts a stock disc brake Sportster rear axle. Lowbrow Customs
Rear Chain Adjusters for 3/4 inch Axles are a perfect fit with this frame. This frame is designed for use with disc brake rear wheels, it will not work with stock, early Ironhead drum brake wheels. Sportster disc brake rear wheels are a perfect fit, as are Cycle Standard 16 x 3.00 inch rear wheels, such as the
Black SKU 010383 or
Chrome SKU 010382. Made in the USA.
