Installation Notes and Tips

Verify rear fitment by year, make, model, and package exclusions before ordering. This Monroe 5993 shock uses a stem upper mount and a loop bushing lower mount, so confirm the mounting style and sleeve dimensions match the vehicle’s original setup. Inspect surrounding suspension components, including bushings and mounting points, before installation to avoid replacing a shock absorber onto worn hardware.
