Family Owned. Dirt Obsessed.
Owned and operated by Dan & Mandy Gnagey, right here in Prescott Valley, Arizona. We build every rig like it's going in our own trailer — with real industry knowledge, attention to detail, and straight-up integrity you can't fake.
More Than an Off-Road Shop
Bad Side By Sides is owned and operated by Dan & Mandy Gnagey, right here in Prescott Valley, Arizona. BAD SXS was built from years of experience, hard work, and a genuine commitment to helping people.
Before BAD SXS, Dan spent many years serving as a Firefighter and Paramedic — dedicating his career to helping others and putting safety first. As a retired Firefighter and Paramedic, he brings that same attention to detail, accountability, and commitment to doing things right into everything he does today.
Mandy also spent many years in the medical field, starting on an ambulance before building her career in pediatrics. Her years in healthcare taught her compassion, patience, responsibility, and how to take care of people — values she brings into the business every day.
We're not a faceless catalog. When you call BAD SXS, you're talking directly to the people whose names are on the building. We know these machines. We ride them. We work on them. And we understand what it takes to build something you can trust when you're miles from home.
Walk through our doors and you'll be greeted by smiling faces — and probably our two four-legged shop greeters, Mac & Cash. They're a big part of the BAD SXS family and are always happy to welcome you in.
Three Things, Done Right
Rolled it? Wrecked it? We work directly with adjusters to restore your machine back to dune-ready — done to spec, done to last.
Turnkey rigs fabricated and dialed in-house. Tell us how you ride and we build the machine to match — no cookie-cutter setups.
Maintenance, upgrades, diagnostics, and bolt-ons. Keep your rig running strong with a shop that actually knows these machines.
Real people, real accountability.
Years in the dirt and under the hood.
Honest answers. No upsell games.
Folks come from all over the state.
Worth the Drive to Prescott
We're up in Prescott — and riders make the trip from Phoenix, Flagstaff, and clear across the state because the build's worth it. Roll in, talk to the people who'll actually turn the wrenches, and leave with a rig that's dialed.
