Description
If you’re running a high-RPM Sportster engine, your factory tappets are likely introducing harmonic distortion that’s costing you efficiency and precision. The JIMS Tappet +.005 XL is engineered to eliminate that slop with a solid roller design that tracks the cam lobe accurately across the entire RPM band—critical whether you’re on the strip or carving through aggressive street builds. This is the upgrade that separates dialed-in top-end performance from guesswork.
