Crazy Stu in partnership with JAP Racing has developed bump stop chassis screws that remove chassis wear and gouging caused by the factory droop screws, as well as ensuring more consistently maintained droop settings.

Stu' Screws have been manufactured with Crazy Stu's world renown expectations of durability for those that like to play HARD. These feature 10.9 grade high tensile steel construction, zinc plating, M5 thread, and a custom large surface area head to provide some of the best wear properties available.

Tools required:

-M5 Tap
-4.2mm Drill bit
-Red thread lock
Installation instructions:
1. Simply mark where the bump stop screw locates on the chassis.

2. Drill a 4.2mm hole.

3. Tap an M5 thread.

4. Insert droop screws and secure with red thread lock.
