Proper installation of your split shackles is key to ensuring optimal performance and minimizing unwanted noise or movement. Follow these steps for a smooth, secure fit and proper thread engagement between the cap screws and pin threads:
Step 1: Initial Install Without Nylon Washers (Rattle Rings)
-
Install the shackle without any nylon washers.
-
Tighten the cap screws to hold the shackle in place.
-
Do NOT torque the bolts down yet.
Step 2: Test Fit Nylon Washers (Rattle Rings)
-
Hold up the correct-size nylon washers in the gaps between the mount and the shackle hooks. Washers should not be used on the outside between the cap screws and the hooks. They should only be used in the middle between your mount and the hooks to fill gaps.
-
Only use enough washers to fill the gaps on either side of your mount snugly—no more, no less.
-
Example: If one 2.0mm washer on each side fits best, use that.
-
Step 3: Final Install With Washers
-
Remove the shackle and reinstall it with the nylon washers you selected.
-
This time, torque the cap screws to spec: 20–30 ft-lbs.
Final Check
The shackle should slightly compress the Rattle Rings nylon washers, creating a snug, quiet fit with just the right amount of resistance. This prevents excess movement while allowing proper articulation.
