JIMS Hydrosolid Rocker – Manufacturer Ref. 1800

The JIMS Hydrosolid tappet provides a versatile solution for vintage and touring Harley engines that require both low-end flexibility and high-end rigidity. Designed and manufactured in the United States, this hydraulic-style tappet operates as a hydraulic lifter up to around 5,500 RPM and then behaves like a solid lifter above this RPM, offering a more responsive valve train. According to JIMS, this transition can free up approximately 3 to 6 usable horsepower in the high range, without stressing the hydraulic pump like a traditional hydraulic lifter.

Ideal for Vintage/Classic, Touring, and Roadster universes, this rocker particularly fits Softail 1340 (1999) and other listed Harley variants. Important note: installation requires the use of adjustable pushrods for precise adjustment and optimal reliability. This product is intended for riders looking to enhance their engine's RPM stability and valve train responsiveness while maintaining the comfort of a hydraulic lifter in regular use.
