I have a 94 runner that when I sas'd it with a 5 leaf RUF pack it was almost even with the pro comp lift the previous owner had on it. As you know the 94 had a stock 4-link in the rear,so I thought I might be able to get away with leaving the rear alone and running with it that way. After a week of DD I was not happy with it, it had crazy driving characteristics. When driving in turns the ass end was all over the place when I hit bumps in the road at speeds over 35 it would feel like the rear was trying to merge to the left or right.
As far as a linked suspension on a Yota, they're great for rock crawling. If set up properly they flex like nothing I've ever seen, they don't have axle wrap issues like leaves but IMO drive very erratically. They have a tendency to torque steer under power and especially in turns,not something I would want to DD. Not saying that all of them out there have poor driving characteristics just the ones I have driven and that includes Yotas that have the TG 4-link kit installed.
Previous Yota's I've had in the past had leafs front and chevy 63's in the rear. It's old school but it is IMHO easy and predictable,DD is nice (drives like a truck) and flexes great. So needless to say I'm in the middle of my Chevy 63 swap in the rear of my runner. Check out my build "My 94 Runna!" it's been raining this week so build has been at a standstill, but I should be good Saturday to start up again. Another thing about Chevy 63's is that they're cheap I paid $100 for mine it's a 3 leaf with overload. And my front RUF pack cost me $150 to build out of 2 sets of rear leafs from an 85 and a 90 Yota.
