Trx4 Axles with Axial Transmission. Advice for Class 2 Comp Build Please.
 

I'm looking in to building up a really capable Class 2 Hilux. My requirements are:

Overdrive. (More than Hot Racing ar44 provide)
Low C of G

I've considered something like a gspeed or Crawl Space chassis with Axial transmission but it's just how to get the overdrive. So I then thought about a pair of trx4 axles with over/underdrive.

Could I then run a 540 instead of a 550?

Any more options would be great"thumbsup"

Being in the UK, I'm trying to stick to readily available parts rather than bespoke transmissions etc...

The trx4 axials will raise the CofG unless you buy specialized chassis with higher arches for the axles like the toyzuki v3. Personally I think the benefits of overdrive are less important then the CofG you you would lose. Rc4wd makes some transfer cases that can add overdrive from what I hear. I think it's from swapping the deiveline input to the front output on transfer cases with reduction.

Hi Neilus

I'm doing the same as you just for fun no comps and I too live in the UK.

I've gone with a sucker punch chassis ( not arrived yet) axial Trans with dig, an ar60 front axle and ar44 rear axle to get od / ud

Hoping to use a tekin fxr with bigger cap to run a Holmes 550 27t trailmaster.

If you see anything wrong please say something I would benefit from another opinion

Good luck with your build

Cheers

Hi Mr. D.

Just had a look at that chassis, it looks nice. I'm after more of a scale chassis, but i think I've decided to just use the TRX4 for now, and see how that goes. If it still doesn't perform as i want, then i'll probably go for a Crawl Space Game Changer Chassis. We'll see at the G6 "thumbsup"
