Real Builds. Real Installs.
At 4R Customs we don't just sell parts — we install them. Over the years we’ve taken 4Runners down to the last bolt and rebuilt them into some seriously capable rigs. From suspension installs and lockers to full interior swaps, engine rebuilds, custom lighting, and crazy electrical systems, we've spent countless hours wrenching in the garage figuring out what works best.
Our install guides are built to help other 4Runner owners tackle their own projects with confidence. Whether you're installing headlights, upgrading interior parts, wiring lighting, or building a full overland rig, these guides walk you through the process step by step.
If you ever get stuck during a build, our team is always happy to help.
