Jims Tools 1800 Hydrosolid Tappet Anti-Pump Performance Upgrade

The Jims Tools Hydrosolid Tappet is a high-performance valve train upgrade designed to safely increase horsepower at higher engine speeds. This innovative tappet features an anti-pump-up design that transitions to solid operation above 5600 RPM, eliminating hydraulic lifter collapse that can limit high-RPM performance.

Key Features:

• Adds 3 to 5 horsepower gains above 5600 RPM through the safe RPM limit of your valve train
• Anti-pump-up device prevents valve float and maintains proper valve control at high engine speeds
• Compatible with any camshaft combination for maximum versatility
• Simple installation process with no valve train modifications required
• Prevents valve-to-piston contact by maintaining solid tappet operation at high RPM
• Designed specifically for Harley-Davidson Evolution and Twin Cam engines

The Hydrosolid design combines the quiet operation and low maintenance of hydraulic lifters at normal operating speeds with the performance advantages of solid lifters when you need them most. Perfect for riders looking to extract maximum performance from their engine without compromising streetability or reliability.
