Q: Is this something I can install in my garage, or should a shop do it?

It is a bolt-on suspension job with no cutting or welding, but it does need spring compressors and a torque wrench along with a proper jack and stands, so it lands as an intermediate DIY. Budget an alignment afterward since ride height changes. If you would rather not tackle it, Unplugged Performance can install the kit at our Hawthorne, California shop, and we ship the shocks preset to baseline so tuning is optional.
