I'm Brent, 33-year manufacturing engineer, owner of AX-Mfg. I got tired of eyeballing whether a loaded rig was actually safe or just felt fine, so I built Rig-Locker to run the math instead.

It calculates Static Stability Factor, center of gravity height, axle weight distribution against GAWR, and safe side slope in degrees — not g's, degrees, the number that means something when you're looking down a sidehill. Every vehicle in the database is documented, not a guess: 43 OEM-sourced rigs, plus enter-your-own for anything we don't carry yet.

Free payload calculator, no signup: ax-mfg.com/payload-calculator/
Full app: Rig-Locker Lite is permanently free. Rig-Locker Pro is $179 one-time — no subscription, lifetime updates. Founding pricing is $129 with code FOUNDING while the first 150 units last.

I'm not here to blow up the tech threads. If you're working a CG, GAWR, or stability question, tag me or drop a reply — I'll run the actual numbers, not a guess.

I couldn’t get the link to work.
Maybe this one will…

Interested, and just started browsing your info, but does this work for a completely custom rig built from the ground up?
Is it designed primarily for how to pack a rig, or can you use it while building one to make predictions and get guidance while building? Wanting to build very flexy 3-4 link systems.
