You’re sitting in your garage with a cold drink, staring at your truck and wondering, “Will 37s fit my truck?” We’ve all been there. MetalCloak can help, making your life a whole lot easier with a suite of easy-to-access free vehicle calculators.

The off-road suspension and armor manufacturer out of Rancho Cordova, California, has dropped a brand-new, totally free suite of AI-assisted vehicle calculators designed for automotive enthusiasts. These pro-grade tools calculate tire size, gear ratios, crawl ratios, suspension geometry, final drive, pinion angle, and more, instantly.

“These calculators are born from one simple thing: listening to our customers,” says Matson Breakey, Co-Founder and VP of Marketing & Sales at MetalCloak. “They asked for smarter ways to make decisions, and we delivered with free, pro-grade tools that help them do just that.”

Smarter Builds, Fewer Regrets

Whether you’re planning your first suspension lift or chasing that perfect low-range crawl for Moab, these calculators make the math easy. No more digging through gear charts or second-guessing a build before ordering parts. Just plug in your specs, hit go, and get the numbers you need.

MetalCloak IQ’s free vehicle calculators for enthusiasts include:

• Interactive Tire Size & Speedometer Correction – Know how your speedo will read before swapping rubber.
• Crawl Ratio & Final Drive Analysis – Perfect your setup for the rocks.
• Gear Ratio Planning – Match your gears to your tires for max performance.
• Roll Center Geometry & Suspension Dynamics – Get the handling you want.
• Plus: Fuel Consumption, Wheel Offset & Backspace, Horsepower & Torque, Center of Gravity, Load Distribution, Torque Spec Conversions, Ramp Travel Index (RTI) & Curb Travel Index (CTI), and Tire Pressure.

All of them are web-based, mobile-friendly, and designed for real-world use.

From Race-Level Knowledge to Your Garage

In the past, this kind of data was mostly for engineers and race teams. Now, as Matson puts it, “We don’t hide information behind dealer paywalls. If it makes you a better builder, we put it in your hands.”

From its bolt-on long-arm suspension kits to its body armor, MetalCloak has a track record of shaking up the off-road world. These calculators are just the latest in the company’s “for the people” approach.

AI Helping, Not Replacing, Off-Roaders

Here’s the cool part: these tools use structured AI logic to help predict how your mods will actually perform. Rather than replacing wrench time, it’s making sure every wrench turn counts.

They’re free forever, and no login is required. Just head to metalcloak.com/offroad-vehicle-calculators, punch in your numbers, and start planning your next build like a pro.

As Matson sums it up: “Whether you’re building your first trail rig or your tenth rock crawler, these calculators give you the knowledge you need to do it right.”
