okay i am wantin to do irs on my xcab yota an i am wantin to know how well it will work an what i have to watch for. an will i have any problems out of it for that i am goin to drive it alot. what is the ups an downfall of irs setup?
IRS rides better, handles better. problems are its a pain to setup correctally and there are more parts so more stuff to break. on a bagged truck it limits lift cause the cv joints can only extend to a certain angle and after that they break. ALso cause its irs you are going to have camber in the back with is cool if you like camber, or a pain in the ass since it wears tires. you can engineer it out of the suspension travel if you know what you are doing...again thats all about setting it up right. you do get a cool factor of being able to keep most of your bed stock if your setup is correct. so ya...good luck!
Thanks I'm not to worried about gettin alot of lift. I drive my single cab just 2 inches off the ground so I know what I need for lift. But since I am gonna be bodied I will be a lil lower. I am wantin to set it up where the ride height is low with out having much camber. I just want it to camber more at lay out. I am just wantin to know if I plan to go this route an it's built correctly would I have many problems out of it if I drive it daily. The reason I am wantin to do IRS is so that I can keep the bed stock. Cuz it's gonna have 20s on it. An I don't wNt to flair the bedsides I think that will look retarded on a yota
Ok let's try this again. Is there anyone that knows how to install the IRS that can help me out on it. Also I have a IRS rear end out of a Lexus sc300 is that a good rear end to use? Any help would help me out.
Yah Id use the sc300 rear end. I dont know how to set it up or fabrication wise however Ive had one of those cars and they make a lot of aftermarket stuff like coilovers heim joints springs so on so forth but yah not in a bagged truck maybe if you had a swapped truck or something. I know they make an airstrut kit for that car so maybe you could run that in the rear and still bagged in the front.
They did a IRS rear on a ford ranger on a epsiode of the show trucks. I think it was last weekend. Theres was bolt in and seemed pretty simple. Gotta figure out where the center is, line it up and whatnot then weld, brace and gusset everything in. Im sure theres more to it though. Also like what was mentioned before, with more moving parts theres more things that could break.
Ive dealt with some IRS setups. The ones Ive seen work best are RX-7, Merkur, and Supra, all of which carry the same bolt pattern, Ive seen a few use air cylinders on the rear to gain lift and are able to 3 wheel lol. Its all about looking at the IRS setup and your frame and making it work for you
^ Yup. A few other common IRS's would be from LS400 (looked beefy to me!), 300ZX (popular i heard), and maybe a wrecked 350Z if you find one (something new!)
And measuring for your driveshaft so it works properly. I don't think the irs from that lexus will be easier to break. The only things that could be easier to break would be bad fabrication of the mounting of the whole irs assembly, incorrect bag on bar setup, driveshaft and pinion angle. Just another though how to run the exhaust might get tricky (dump before rearend or run it high over the rearend)
