Skid Plates, Rock Sliders & Armor in Sun City, AZ
Protect the expensive stuff underneath — skid plates, differential covers, rock sliders, and bolt-on underbody armor, installed so your rig can take a hit and keep going.
The desert and the trails around the West Valley are hard on the underside of a truck. Rocks, ruts, and high-centering can crack an oil pan, dent a fuel tank, or bend a differential cover — repairs that cost far more than the armor that would have prevented them. Skid plates shield your engine, transmission, transfer case, and fuel tank, and rock sliders protect the rockers and body while giving you a solid point to pivot on an obstacle.
This is bolt-on protection — no cutting or fabrication — matched to your vehicle's mounting points and installed to take real abuse. Because armor adds weight down low, correct, secure mounting matters, and so does knowing what actually needs protecting for how you drive. As a full-service shop, we know these trucks inside and out and set up protection that's genuinely useful, not just heavy.
Tell us where and how you wheel, and we'll recommend the skid plates, sliders, and covers that make sense for your rig and quote them out the door, parts and installation included.

FAQ
Which skid plates do I actually need?
It depends on your vehicle and how aggressively you wheel. The most valuable are usually the engine, transmission, and fuel-tank plates, since those protect the most expensive and vulnerable components. We'll recommend a package that matches your terrain and budget instead of selling you armor you don't need.
Do rock sliders replace my running boards?
They can — rock sliders are built to bear the vehicle's weight against obstacles, and many people use them as a step too. If you want protection first with step functionality, sliders are a great choice. We'll help you weigh sliders vs. steps for how you drive.
How much weight does armor add?
Full underbody armor adds meaningful weight down low, which is why we help you choose only what you'll benefit from and mount it securely. For most daily-plus-trail rigs, a targeted set of plates and sliders is the sweet spot.
How much does skid plate and armor installation cost?
It depends on how much protection you want and your vehicle, but you'll get one out-the-door price covering parts and installation before we start. Tell us how you wheel and we'll quote it.
