Upgrade your Harley Davidson EL engine with the V-Twin Lower Valve Spring Cup Set, designed specifically for 1936 and 1937 models. This complete set includes four snap-on tops and bottoms, ensuring a secure fit for each valve. Crafted to match the original specifications, these cups are essential for maintaining proper valve operation and engine performance.

Proper installation involves pre-forming brake lines using a brake line bender, with careful alignment to the rocker boxes to ensure optimal function.
