Did a broke kid from Pahrump just solve the 4 Wheel Drive Trophy Truck Reliability problem?

I don’t know whose 4wd tt has the portal axle set up on their front a-arm suspension, but if it works, it’s a major improvement. Not only for the improved cv angularity, but also ground clearance.

Samco Fabrication put Hummer portal knuckles with inboard brakes on Chad Hall's 4WD 6100 truck but he has parked the truck since he got GM backing to drive the Colorado ZR2 in Stock Mini.

Doesn't Armada or Tubeworks do front a-arm portal assemblies?

Armada built portal hubs for Cody Waggoner’s Ultra4 car, don’t know if they have built any yet for desert trucks.

That Mason truck was no slouch at the 500...to say the least! Props to the Mason boys and RJ for a good first outing for the beast!

so I've been reading on this in some other threads and have not seen this idea proposed anywhere. why not set up a transfer-case that utilizes differentials that already exist. you could have a setup like a 203 (full-time) which is an open diff to the axles which distributes torque more or less evenly between the axles. or a 205 that distributes rpm evenly like welding a differential you even have viscous clutch t-cases like a limited slip but what if you used something like a Detroit locker in the t-case allowing you to give all the power to whichever wheel is spinning the slowest. if you make the case properly you could you diff carriers straight out of different size axles depending on your power level and weight you can have.

place a spur gear on the output of the transmission. attach a spur gear to the carrier rather than a ring gear and use the axle shaft outputs as the t-case outputs. this will mean both the front and rear outputs will be offset like in a drop down t-case.
