Well if your just making a mall crawler I dont see the point in doing the SAS and such, alot of cash for no real use.

But if you must I would upgrade to 5.29 gears so you have some power on the road.

Okay cool I was told 4.88 gears from Fat Rat Enterprise were I live. I have a axle allready and I cant lift it enough without a SAS. I have tried a body lift and a torsion bar upgrade it just caused a lot of issues with the IFS suspension. I have a D44 that is worth 2500 dollars I bought it from extreme gear offroad. I decided it would save me some stress dealing with the build of a axle. If you know anyone looking for a d44 front or a dana 60 rear for a toyota let me know i have all the parts just about and have spend hundreds of dollars on the axles.
Thanks for writing back I will probably go with the 5.29 if its better for street driving.

I think it would be better for street driving, would return more topend.

I hope it all works out for ya, but imho SAS and shoot for 35's. Wit an SAS it will be higher looking than a IFS lift and it will do well offroad and 35's are an ideal size imho for most.

Overall the drop frame lifts are the problem, the components are usually made of weaker steel and tend to not be heavy enough, hence why Erik modified his a bit (check his webpage).


I am not sure what fabricator here could do it, but I know on ultimate yota and yotatech there are a few that are much better equipped and knowledgeable than the one you have used thus far.

Good luck with it dude.

I can only report what I've found on my own truck and it may be due to other problems, but here's the result of my pondering gearing with respect to larger tires:

I have 33's on my truck and stock gears. I definitely notice that it feels like it's geared improperly for the tires. It's kind of like starting in 1.5th gear rather than 1st. Besides the issues with starting up, I believe that it also affects the gas mileage. Since the gears are effectively too high with the larger tires, I find myself one gear lower than I should be for the speed. This results in lower mileage. The alternative is to go up the gear, but then I lug the engine which isn't great either.

This is for road driving too. For off-road, the situation's worse. Even in 4-low, I find myself going faster and bouncing off the bumps harder than I prefer.

In short, if you are going to go with bigger tires, re-gear your diffs. I'll be doing that this spring I think. (money, job, etc. permitting)

Chip

ditto that.

Thanks for all the replies everyone.
I am going to gain 3 to four inches on whatever spring size I choose. The way I am going to mount the srpings to the frame, is going to add 3 inches maybe a tad bit more.

So im thinking of not using my springs I have and going with a toyota spring around 4 or 6 inches. I should be able to fit 37's pretty easy.
