Teraflex – JK Front SpeedBump Spring Bucket Jounce Tube Brace Kit:
The factory JK spring guide & jounce tube can deform during hard compression and suspension movement. This jounce tube brace adds an extra layer of protection from damage. Does not work with the factory bumpstop ‘bell’ cup – this is designed only to work with TeraFlex SpeedBump bumpstops. Bolt on installation.
