The most premium axle adjusters on the market. These chain tensioners are designed for 1936-1972 Harley Davidsons, and will fit any aftermarket hardtail with a stock style axle plates, such as SKU 017933 Lowbrow Customs Weld-On Hardtail Frame for 1958-1984 Harley-Davidson Panhead & Shovelhead.

Thread dimensions are 3/8-24 x 3” long. They feature a 3/8” hex head and relieved threads on both ends to ease in assembly and maximum useable travel. Threads are roll formed into aircraft grade 17-4 stainless steel. This process produces a superior surface finish and shape to traditional cut threads, while simultaneously work hardening the base material. The result is the smoothest functioning, strongest threads available today. 

Replaces Harley-Davidson OEM # 41576-36.

As always - designed, prototyped and machined in the Pacific Northwest, USA. Sold as a pair, chrome lock nuts included.
