SEMA 2025: ICON’s Most Advanced Long-Travel Systems Debut On R&D Tundra

There’s nothing subtle about the 2022 Toyota Tundra dominating the ICON Vehicle Dynamics section of the Randy’s Worldwide booth at the 2025 SEMA Show. Wide fiberglass fenders, towering 38-inch tires, a wall of KC lighting, and serious long-travel hardware on full display make it clear this isn’t a parts catalog prop or a mild weekend wheeler. It’s an unapologetically aggressive, fully functional off-road development platform — one that has spent the past several years being pushed to the limit as ICON’s flagship R&D mule for the newest-generation Tundra.

ICON has owned this truck since late 2021, using it to vet, refine, and torture-test every suspension component the company has engineered for the platform. It has lived through every stage of development — from basic leveling components to complete long-travel systems — making it the most thoroughly evolved and purpose-driven Tundra in the company’s history. And at SEMA 2025, they unveiled its most advanced form yet.

Long Travel, Fully Realized

The centerpiece of the truck is ICON’s new 3.5-inch-over, long-travel suspension system. A set of billet aluminum upper control arms features the brand’s latest Delta Joint Pro with double-adjusters, offering fast and precise alignment capability. Down below, ICON developed a new style of lower control arm bushing designed specifically to eliminate the squeaks, pops, and binding common with uniballs or polyurethane alternatives. The result is a quiet, highly compliant front end that cycles an impressive 13 inches of wheel travel.

Managing that movement are dual three-inch shocks per corner. A remote-reservoir coilover equipped with ICON’s electronically controlled CDE Valve adjusts compression on the fly, while a matching three-inch secondary bypass shock — with its own CDEV system — adds tunable stability for high-speed desert terrain. Because Toyota’s factory sway bar is unusually aggressive on the new Tundra, ICON replaced it with a custom torsion-style sway bar using billet aluminum arms, providing the roll control the truck needs without the harshness of the OEM setup.

Big Tires, Big Brakes, Big Power

Stepping up to 38×11.50 Nitto tires on custom-chromed ICON Recon Pro wheels meant the stock Toyota braking system was no longer up to the task. Wilwood stepped in with a six-piston front brake package engineered specifically for this vehicle, giving the Tundra the stopping power its long-travel capability demands.

With tire size increasing, gearing became a challenge. The aftermarket currently offers limited gear options for the new Tundra platform, so rather than bog the truck down with oversized rubber, ICON partnered with Magnuson. The resulting performance package — which includes a low-temperature radiator, upgraded charge-air cooler, dual cold-air intakes, exhaust system, and tune — adds roughly 85 horsepower. It restores the truck’s eagerness and helps it carry speed across desert whoops with authority.

OEM Styling With Real-World Upgrades

To maintain a subtle, factory-enhanced aesthetic, ICON sourced custom fiberglass from FiberwerX and had it painted to perfectly match Toyota’s OEM color. The bumpers were fabricated in-house, and KC HiLiTES supplied a full lighting suite, from the Pro6 roof-mounted array to auxiliary and fog lighting.

Lighting performance received a major bump thanks to Alpharex headlight and taillight upgrades. Since this Tundra started life as a basic SR5 model with entry-level illumination, the difference in brightness and beam pattern is dramatic.

A Premium Interior Reimagined

Inside, ICON transformed the once-basic SR5 cabin into something that wouldn’t feel out of place in a Platinum-grade truck. The original cloth seats and tiny infotainment screen were replaced with a 14-inch OE-style Seicane unit that blends seamlessly into the dash at a fraction of Toyota’s OEM upgrade cost. Katzkin leather upholstery finishes the transformation, giving the cabin a far more premium and comfortable feel during long days of testing.

Prototype Rear Suspension: ICON’s Next Breakthrough

While the front showcases advanced long-travel hardware, the rear suspension is where ICON is preparing its next major release. The prototype package — internally dubbed the RXT Long Travel Kit — has been engineered specifically for this generation of Tundra and cycles an impressive 16.5 inches of wheel travel. The system features longer coil springs, revised upper links designed to clear the fuel tank, a bolt-on shock hoop, and extra-long dampers. Only minor trimming was required during development, and the production version is expected to offer around 14 inches of travel while remaining fully bolt-on.

Built For Chase-Truck Duty

Although it wears certain overland-oriented components, this Tundra isn’t meant to be a rolling campsite. Instead, ICON designed it as a go-fast overland-style chase truck — something capable of carrying tools, equipment, fluids, and spare parts at speed across desert terrain during R&D sessions.

Overland Vehicle Systems supplied the composite truck topper, which provides a durable, sealed workspace. ICON plans to mount nitrogen tanks and tools inside, while a DECKED drawer system keeps gear organized. A massive slide-out tray offers room for a fridge or cooler, making it invaluable during long days of testing and tuning.

A SEMA Build That Won’t Sit Still

Unlike many vehicles built specifically for the show floor, this Tundra’s time under bright lights is temporary. Once a few lingering wiring and finishing touches are handled back at the shop, the truck’s next stop is the desert — where ICON’s engineering team will push it hard, collect data, and continue refining the production-ready systems born from this platform.
