Overheating kills trail days fast. That’s exactly why Wide Open Design developed our Dual Pass Radiator Combo Units specifically for serious off-road use. In this video, Adam breaks down:
* radiator sizing
* SPAL fan airflow
* cooling performance
* LS/LT engine cooling
* radiator mounting
* fan shroud design
* why CFM matters so much
We cover both WOD radiator combo sizes:
* 31” x 15.5” dual-pass radiator
* 27.5” x 15.5” dual-pass radiator
Both systems feature:
* TIG welded aluminum tanks
* soldered radiator cores
* oversized SPAL fans
* clamp-style fan shrouds
* -16 AN fittings
* off-road specific mounting solutions
The goal was simple: build a radiator system that keeps high-horsepower off-road rigs cool in the harshest conditions possible.

![Jeep LJ Tube Frame & Chassis: CAD Overview from Wide Open Design
Jeep LJ fans have been asking for it for years, and now its finally here.
In this video, Adam Woodlee takes you behind the scenes of the Wide Open Design Jeep LJ Chassis and shows how the entire platform was developed in CAD before the first production chassis was built.
We cover:
• Jeep LJ chassis design
• One-ton axle packaging
• Link geometry
• Radflo coilover and bypass shock integration
• LS / TH400 / Atlas drivetrain fitment
• PSC steering ram mounts
• Fuel cell placement
• Skid plate systems
• Builder-friendly chassis kits
One of the biggest goals behind this project was making it easier for customers to build their own Jeeps at home. By designing every bracket, truss, shock mount, and drivetrain component together, weve created a complete system that works as one package.
If youve ever wondered what goes into designing a modern Jeep tube chassis, this video gives you a full look behind the curtain.

The Jeep LJ (Unlimited) has a cult following for a reason, but finding a chassis that respects its longer wheelbase while providing master-level performance is rare. In this deep dive, we take you from the CAD screen to the shop floor to reveal our new LJ Tube Frame Chassis [00:10]. We’ve engineered this frame to accommodate the LJ’s unique 15-inch-longer tub while integrating high-performance features like 14-bolt front and rear axles [01:43] and bypass shock mounts [05:10]. By designing the entire system in CAD—from the PSC steering ram mounts [02:32] to the rear sway bar geometry [02:51]—we provide a fluid build experience for the DIY enthusiast. Whether youre running an LS engine or the new hotness Coyote motor [13:39], our chassis ensures that everything from your driveshafts to your links cycles perfectly with full 14-inch travel [12:39].
