Sleeper builds are the ultimate flex in the off-road world. You pull up to a trailhead looking completely stock, maybe even a little beat up, and then proceed to absolutely send it past rigs that cost three times as much. That’s exactly what Rock and Road Performance pulled off with this ‘03 Yota Taco PreRunner that looks like your neighbor’s grocery getter but hides some seriously gnarly suspension underneath.
This 1st Gen Taco came into their shop as a two-wheel-drive V6 that needed to party harder than its stock setup would allow. The team at Rock and Road had one mission - build something that could handle serious terrain while maintaining that sleeper aesthetic that makes other wheelers do double-takes.

The front end got the full Total Chaos treatment with lower control arms, uniball conversion kit, and heim steering. They paired that with ADS 2.5" coilovers that received custom valving work and a spring rate drop from 600 down to 450. That might sound backwards to some folks, but dropping the spring rate allowed them to get more creative with the shock tuning, making the suspension more compliant for daily driving while still handling the big hits.
The real genius shows in how they mounted the ADS hydraulic bump stops. Instead of just slapping them wherever they fit, they outboarded the bump stop as far down the lower control arm as possible. This gives more effective bump control at the top of the travel range and preserves more of that sweet ride zone before the bump stop kicks in. They even fabricated a custom aluminum strike pad because the mounting location was close to the edge of the control arm (that’s called attention to detail my dude).
The rear suspension is where this build gets absolutely wild. Most shops would tell you that running big shocks with serious travel means C-notching the frame and modifying inner fender wells. Rock and Road said “hold our beer” and built a custom cantilever system that houses ADS 3.0" x 14" travel MBR internal bypass shocks without touching the bodywork.
They’re running a spring-under setup with F55 Deaver leaf springs and custom 12" shackles. Those long shackles drop the effective spring rate way down, letting the shock package do all the heavy lifting for suspension control. The cantilever system connects to a Trail Gear 8.4" fabricated housing, but here’s the cool part - they retained all the factory semifloat cups, ABS sensors, brakes, and parking brake assembly. Everything functions exactly like stock.
The shock package delivers about 17" of bump-and-strapped travel with ADS limit straps and 2.5" by 2" travel hydraulic bump stops. That’s serious desert runner territory hiding under what looks like a bone-stock truck bed. They even ditched the factory load-sensing proportioning valve for a Wilwood manual unit, which really opens up the brake feel and lets you dial in exactly what you need.
What makes this build special isn’t just the technical execution - it’s the philosophy behind it. This Taco sits only about an inch and a half over stock height on 32" tires. Park it next to a mall crawler on 35s with a light bar, and nobody’s giving it a second look. But when the trail gets gnarly and that fancy rig is picking lines carefully, this sleeper is floating over everything at twice the speed.
Rock and Road Performance really knocked this one out of the park. You can check out more photos and specs on their website at rockandroadperformance.com, and follow their Instagram @rockandroadperformance for more builds like this.
This Taco proves that the best off-road rigs aren’t always the ones that scream for attention. Sometimes the most capable machines are the ones that look like they rolled off a used car lot. When you see a clean but understated rig at the trailhead, don’t sleep on it - it might just be packing enough suspension to make your fancy crawler look silly.
