Install Time Guide: How Long Common Car Mods Take

Getting a new look or performance boost for your ride is exciting, but nobody wants to be stuck in the garage for weeks. Knowing the typical install time for a mod helps you plan the work, budget, and whether you can DIY or need a pro.

Typical Install Times for Popular Mods

Wheel spacers – Most DIYers finish the job in 30‑45 minutes per axle. The steps are simple: unbolt the wheels, slide on the spacers, tighten the lug nuts, and do a torque check. If you’re fitting spacers on all four wheels, add another 15‑20 minutes for the extra safety checks.

Body kits – A full front and rear kit can take anywhere from 4 to 8 hours for a seasoned installer. The time varies with the complexity of the kit, bolt‑on versus weld‑on design, and how many trim pieces need alignment. Expect a professional shop to spend a full day, while a confident DIYer might spread the work over a weekend.

Tinting windows – A single‑car tint job usually runs 2 to 3 hours. The process involves cleaning the glass, cutting the film, applying it, and removing bubbles. Adding a second layer of tint adds roughly another hour.

LED headlight conversion – Swapping halogen bulbs for LEDs takes about 20‑30 minutes per headlight if you have the right brackets. Some cars need a new wiring harness, which can add another 15 minutes per side.

Lowering springs – Replacing stock springs with lowering springs typically requires 1.5 to 2.5 hours per axle. You’ll need a spring compressor, which adds a few minutes for setup and safety checks.

Tips to Speed Up Your Install

Start with a clean, well‑lit workspace. A cluttered garage adds minutes you’ll never get back.

Gather every tool before you begin. For wheel spacers, a torque wrench and lug wrench are enough. For body kits, have a socket set, trim clips, and a rubber mallet handy.

Follow the manufacturer’s torque specs. Tightening too loosely means you’ll have to redo the job, while over‑tightening can damage parts and waste time.

Use a friend or a helper for larger parts. Two pairs of hands can halve the time it takes to line up and bolt on a body panel.

Take short breaks, but keep them brief. A quick coffee is fine, but a long nap will stretch the install well beyond the estimated time.

Finally, test‑drive after every major step. A quick roll around the block will reveal misalignments before you commit to the next phase.

With these time estimates and shortcuts, you can decide whether a mod fits your schedule or if you need to book a professional. Knowing the install time also helps you avoid surprise downtime and keeps your car looking and performing its best.
