FS: AR Design N54/N55 Downpipe Exhaust bolt set
-Brand New- AR Design N54/N55 Downpipe Exhaust bolt set Includes class 10.9 Metric hardware (145,000PSI tensile strength, C32-C39 Rockwell, Zinc Plated) and Nord-Lock positive locking re-usable washers. These washers use a wedge locking action to create tension instead of friction to create a positive lock. When the bolt and/or nut is tightened the teeth grip and seat the mating surfaces. The NORD-LOCK washer is locked in place, allowing movement only across the face of the cams. Any attempt from the bolt/nut to rotate loose is blocked by the wedge effect of the cams. Kit Includes: 4 class 10.9 zinc coated metric bolts 4 class 10.9 zinc coated nuts 16 Nord-Lock washers Price is $14 shipped within the us. Paypal add 3.5% extra |
