Frequently asked questions

Do I need to purchase parts through RAD Supply Co?

No — you’re welcome to bring your own parts. That said, we sell most of what we install and can often get it to you faster. If we supply the parts, we can bundle installation into one order.

How long does installation take?

It depends on the job. A coilover swap typically takes 3–5 hours. A wiring harness or rack build can range from 1–4 hours. We’ll give you an honest time estimate when we quote the job.

Do you work on all vehicles?

We specialize in trucks, SUVs, and off-road rigs — especially Ford Bronco, Tacoma, 4Runner, Wrangler, Gladiator, and similar platforms. Reach out if you’re not sure whether we can handle your build.

Is there a minimum job size?

No minimum, but we do charge a flat service fee for any appointment. That fee is applied toward the total labor cost.

How far do customers typically drive to get here?

Most of our customers come from Riverside County and southern OC — the Temescal Valley location is a straight shot off the 15, making it an easy drop-off from Temecula, Lake Elsinore, Corona, Murrieta, and Mission Viejo. We’ve also had customers come from San Diego and the IE who heard about us through our articles and product reviews.

Where exactly are you located?

We’re based in Temescal Valley, CA (92883), just off the I-15. Our exact address is shared when your appointment is confirmed — we’re a private shop, not a walk-in storefront.
