A perfect budget friendly upgrade for both stock bore and big bore builds. **Specifications:** - OEM spring measures at 1.3mm thickness - CJR spring measures at 1.6mm thickness Installation is easy - Once the clutch cover is removed, simply unbolt the 4 bolts holding the lifter plate, remove the OEM spring and replace it with the HD spring. Re-install the 4 lifter plate bolts to 9 ft/lbs and you’re ready to ride! **Note:** Can only be used with OEM clutch, this will not work with the 6 spring clutch kits. ## Shipping and returns - Flat rate shipping is $8 for parts orders under $75 and free for most parts orders over $75, within the continental 48 states.
