These coilovers do not require a tool or spanner wrench for adjusting ride height. To adjust ride height, you'll need to compress the spring, loosen the set screw on the lower collar, and then turn the collar by hand to the desired ride height. The coilovers absolutely need to be bolted on properly to the LCA with the nuts. If you're having issues with your install, please call us directly at 623-434-5277 or email us at [email protected]
