PROTOTYPE2

decided to swap out the crap ifs and go with the real deal stragith axle i found an axle from a yota pick-up it had approx. 130,000 mile on it the guy wanted $400 for it from the junkyard but i has no front drivshaft wht driveshaft fits? im running a bone stock 1990 sr5 4wd 3.0 with a 5-speed manual trans. im also considering using all-pro's kit has anyone used it yet? i just need some info it looks like its gonna cost me $3,000 installed (Roughlly)

im going with the 4" lift springs and sticking with 2" lift coils and 2.5 inch spacers and a drop braket for the rear bar.
oh yeah dont worry bout power if this works good the next thing to go in is the 3" body lift and a 3.4l supercharged taco engine.
remember i need all the help i can get so lmk what youve got!

what year was your axle from? if its the long gusset one fom 84-85 trucks(gusset goes whole way to knuckle) your original drive shaft is the rite lenght and will bolt up. the 84-85 and 86 and up shafts are the same lenght. i noticed this from stripping the trucks i got to sell parts on ebay that were the drive shaft attaches at the front is the same. if the axle is from a 83 or older you will need the newer yoke. the older trucks used smaller bolts and the pattern was difference. hope this helps.

I believe I read somewhere that the yoke/flange combo on the 90's version diff and driveline have a greater angle of rotation so if you swap the flange from the 90's diff onto the '84-85 you will have better articulation in the driveline.
I want to do a spring over too, but I still have my dead/dying '85 EFI sitting in the driveway. Gotta swap out the whole truck for a 4door first

actually its the 83 and older trucks that have the lower angle of rotation for the drive shafts. the 84-85 drive shafts are the same angle as the 86 and newer ifs trucks. what makes them better is that where the u joint goes into the flange on 84 and up trucks it is a 1/4 of a inch farther from flange than on 83 and older trucks.

See I knew somebody would know the real info on that one. Apparently on the article I read the guy doing the spring over used an '83 front end. Are '84-'85 frontends really that hard to come by?

the only difference in the 84 and 85 axles and the 83 older ones is the lenght of the gusset on the drivers side. the 84-85's they go to the knukle 81-83 the gusset goes to the spring 79-80 have no gusset at all. the yoke is the same only difference is the bolt pattern 84-85 use bigger bolts than the 83 and older ones. the angle of rotation has nothing to do with the axle it is all in the drive shaft. the 84-85 yokes are the same bolt pattern as the ifs trucks. i got a couple of the 84-85 axles but there isn't any advantage really except the gusset actually with the 79-80 axles you would get better ground clearance since they don't have any gusset
