Description
SEVEN SINS BREATHER BOLTS ARE CUSTOM ORDER BUT THIS HERE LISTING IS FOR IN STOCK UNITS.
SEVEN SINS CHOPPERS Original "DIRTY FRANK" Breather bolts. Inspired by the neck bolts in Frankenstein's neck. These are the low profile version perfect for customers needing the extra clearance. These STAINLESS STEEL beauties have a hidden internal machined key area for tightening and feature all stainless hardware and a filter element. Harley as you know, routes the dirty-hot crankcase air back into the air cleaner compromising the performance of your engine. We measure the bolts by the threaded area only so if you order 2.5" bolts then the bolt will thread 2.5" deep. We do not include the head of the bolt in the measurements. All bolt heads are polished stainless. S7NS breather bolts vent the dirty-hot oil out without compromising the longevity & performance of your engine.
Each bolt gets 2 stainless screens and a filter element. The one screen goes in first, then the filter, then the second screen, and then the lock ring.
The new longer bolts have about 1.25" of threading.
