If you plan on really whomping on it you might want to add tie-ins too. Synergy has TJ-specific tie-ins for the A-pillar (top), but for the B-pillar and C-pillar the company only has these universal kits (above). The universal kit covers only one leg, so we needed four of them. Also, you need to provide your own bolts and DOM tube for the universal kits. In both kits the plates are laser-cut and CNC-formed 3⁄16-inch-thick steel and include a bushing and sleeve to isolate vibration.
