My Capra on Ryft axles,Treal rear Vitavon front,Vitavon Portals,Vader flat skid,Amazon 3gear transmission with dig,2.2 pitbull rock beast Alien compound tires with Proline dual stage foams. Just a quick run in my back yard.
I went with 120mm desert lizards all the way around. They are a little big for the front. I'd recommend 110mm for the front just because it's not allowing me to drop it any lower so either 110mm or some shock keys for more adjustment.
So I'm not to familiar with the Trx4 transmission as far as the coupler size from transmission but on this I run the standard wb8 couplers off the transmission into the stock Ryft wb11 drivelines. They bolt right together.
