i have had both an 82' with a 5" lift and an 86' xcab and like everyone has said the 82 would go places the 86' couldn't but if you learn how to drive what you got then you will be supprized just what a yota will do.and yes the 82'with sfa sucks on road

Please explain this!

Learn to search newbie and try to have an original thought!

I have yet to see any competition or serious rockcrawler be IFS, but it really depends on the environment you wheel.

SFA = dedicated trail rig

IFS = streetable wheeler

I love my IFS 08 Tundra but I wouldn't take it wheeling.

Stop letting Jeep owners ask questions. Even in the newbie section this thread is stupid.

Yep, more SFA rigs have rolled than IFS ... but a lot of it is coincidental. The guys who have needed to SAS are the ones running extreme trails where rollovers happen.

Kinda like people break 5.71's ... well, they have big tires, and usually they have big tires because they need them for the extreme trails they run ... so is it because 5.71's are weak or because they are applying more force?

i had quite a different experience.. guess it depends on how and how much you wheel it

Yeah I guess I probably don't wheel it hard enough.

Well then don't make blanket statements like that unless you have some type of fact (or even an opinion of your own) to back it up....thats like the blind leading the blind

So now you're comparing jumping a stock IFS truck to a custom suspension SAS rig?

Why don't they use SFA on Baja rigs then? Because long travel IFS is better for that stuff ...

Do the baja rigs even have 4wd? I ask because I don't know much about it. I was under the impression that many/most of those vehicles were 2wd with all the emphasis on suspension travel. In which case the whole comparison becomes even more obtuse.

I'm not that knowledgable with Baja rigs, but I'm sure there are classes with 4 wheel drives. If memory serves me correctly, Pirate had a team run it in a Cherokee. Regardless, I do know that CORR runs 2 and 4 wheel drives, and they run IFS.

like it's already been stated... each have there own pro's and con's

i must say i like my SFA... i've gone 150km/h with my 35's and had no wobble's... although this was before my accident and with only 70,000 km on my truck and the lift only being a year old.

a friend of mine has an 89' IFS pick up with over 300,000km's... the only thing i don't like about his ride quality, is that he has 4" lift blocks with the stock springs in the rear, having a braket lift up front, seems to be very comparable... my truck having lift springs all around i find ride's better... he also agree's. but that's the rear end and not the front.

and as for 3rd gen runners. you get a nicer interior. if you get a limited you get a rear e-locker. i know 97limited and his 4runner with the sonoran lift and 33's ride's better than stock. although he has custom sway bar end links and poly bushings. for a lifted toy i must say that's the nicest ride i've been in with a lift. 160km/h on the sea to sky highway with about 150 pounds of mountain bikes on his hitch mounted bike rack. takes the corners well. but not many people drive their trucks that fast and hard.

really it depends on what you really want to do with your rig. hard core wheeling/rock crawling. then you may want to go with sfa. not to say an ifs can't handle some rocks cuz they can i've seen it first hand.

It's a fact, but don't just take my word for it:
