• Additional mounting hardware where supplied with the product

Installation notes:

Ultra Racing specifies RL2-790 as a bolt-on installation. The vehicle will need to be safely raised to provide access to the rear lower mounting locations. Position the brace correctly and check clearance around the differential, rear suspension, exhaust and surrounding underbody components before final tightening. Reassemble and tighten all mounting hardware to the appropriate vehicle or manufacturer specification.
