What's up 4GTaco fam!! Check out this recent Trailhunter we wrapped up at the shop. John brought his 2025 Trailhunter in for a full 74Weld portal axle setup and supporting mods to make 37s fit and clear. The truck now runs 74Weld portals, 74Weld billet rear links, an ADD winch bumper, Warn VR Evo 10 S, Rigid SR lighting, hybrid power relocation, and Method 703s wrapped in 37" Toyo RT Pros. The goal was simple. Keep the hybrid system happy, keep the geometry correct with portals, and build a truck that actually works off-road without losing daily performance. Portal service was handled at the 500 mile mark, and the truck left with proper alignment and all clearances dialed in. This setup gives the Trailhunter more ground clearance, stronger axle geometry, better approach angle, and a clean front recovery system. If you’re looking at portals, 37s, hybrid routing, or you just want to know which parts actually work together on the new 4th Gen Tacoma, feel free to reach out. Mountain Yotas is always around for build questions, part recommendations, and helping you plan your setup the right way the first time.

For those wondering, Toyota did give us a lot of what we asked for in this new truck. One crazy important feature, the 9.5" rear axle. This axle is nearly as big as a Dana 60, only .25" smaller. Naturally, they are super strong. You could technically run a 40" tire with relatively little issues. My plan is to run 37s bare minimum in the next few months, and 40s only if I decide to throw it on portals. But I'm beyond stoked on the beefier rear end. Hopefully the front can keep up! The 3rd Gen had a max size of 8.75". While still a good size, these new ones are much better.
