I know a couple guys that are into samis...both have yota axles,,both beat the freak'n piss out of them with stock birfs and 35 boggers..Only one of them has ever broken a birf and that was crawling a car..the fron got wedged in the dash and a-pillar and lots of throtte was used to unstick it..Other then that on the trail a birf has never been broken..so longfeilds wont be needed right away..The are both useing zuki motor,trans and t-cases with the 4.0 gears in the t-case..they both said that with duels there not sure how well a toy duel case trans would fit being as long as they are..possibly just a toy trans with a 4.7 gear set might be the ticket over duel cases..6 inches can be alot in a short wheelbase rig..
one guy is using toy springs and it works really well..I can send you his e-mail if you want to pick his brain..but this sami works killer!
toy springs and axles on 35 boggers..this rig gets it with stock birfs and t-case gears..
