    Downpipe to catback fasteners coming loose, causing annoying exhaust rattles and leaks? Hardware seized up and rusted out?

    Look no further! Our new hardware kit is the perfect solution. 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
    • 8 Nord-Lock or Wave-Loc washers

    If you are concerned about scratching the coating on your coated downpipes, select the "Coated Downpipes" option and we will replace the NORD-LOCK washers with Wav-Loc washers that will not scratch the coating.

    Add our gaskets to your order as well for a complete fastening and sealing solution!
