Author Topic: major advantages to upgrading an 86+ rear housing.... (Read 4300 times)

FSAD · « **on:** May 09, 2006, 12:31:32 PM »

So far the only reason I know of for upgrading to an 86+ rear housing ( i have an 84 PU), is the wider width. Along with this reasoning is that one has to add 1.5" wheel spacers to the front axle for uniformity.

I'm not a big fan of wheel spacers, so unless there are other advantages (stronger housing, etc) to the newer unit, why would you want to do this?

thanks

larger brakes

bigger brakes and more width is it.. they arent stronger.. hell the tubes smash and crack easier..

ok, yeah, brakes, i should have prefaced my post: im planning on doing some sort of disc conversion, maybe even full floater axles.

so just the brakes then??

i figure i can get the "width" i need by rim BS. actually not much different than wheel spacers, but i guess it makes me feel better than spacers AND greater BS'd rims at the same time.

thanks

yep just the brakes and width.

the axles themselves are stronger also and the housing is supposed to be stronger. Besides those your tires are gonna rub your frame bad without the added width

FSAD · « **Reply #6 on:** May 09, 2006, 09:32:27 PM »

ill be building a custom bed, so not worried about rubbing. also, will have aftermarket shafts for what ever setup i settle on (disc setup, full floater, etc)

you are the first ot say the housing is stronger. anyone else think so???

lemme ask you all this....

who is running hte wider rear with 1.5" spacers up front and what do you think of them?

thanks

they rub your frame bad, not rub your bed. Long travel suspensions will benefit from a wider axle needing less of a wheel offset to accomplish the same travel.

Ramrod · « **Reply #8 on:** May 09, 2006, 09:43:52 PM »

you wont need to upgrade the shafts on the ifs rear axle because they are plenty strong and i'd say anyone that has experience in this area will tell you to do the wider rearend

I would say the housing is stronger too. I have ben running this same setup with 1 1/2 inch WS for a little over a year and it has been great. I have had good experiences with the WS i have had, none have ever came loose one bit.

ive never heard anything about the shafts or the housing being strronger, but i definitaly dont know everything

FSAD · « **Reply #11 on:** May 10, 2006, 07:08:55 AM »

thanks guys, i didnt think about the frame, per se, but it could be an issue.

keep the replys coming in. i really appreciate it! it will help me build the right setup the first time.

Go with the 86 housing and axles with a v6/turbo 3rd member and 1 1/2" spacers up front you will be much happier with it and not to mention you will save money over going with after market axle or a full floating kit. bigger breaks to, on mine i used sky's disk brake brackets and only drooped $250.00 on the hole disk brake conversion.

i was planning on getting a third from Marlin, w detroit. i assume that is the same as the v6 turbo or just as good???

marlin sells 4cyl thirds and v6 thirds, the v6 thirds all have larger bearings and a heavier 3rd housing

the shafts are the same strength, but you gain a larger diameter axle tube(if that means anything, they're all sheet metal on toys) and bigger drums.

call me crazy, but i like my narrow track axle, lets me get into tight spots, but i like pizza cutter tires so what do i know

I have the same housing as the '84 we had them on the diesel trucks til 90 something... I have 1,5" spacers bouth front and rear and have been driving with them for over a year now with out any problems. (except for broken pinion bearing after a long and hard jump) I don´t thing the spacers have addet more stress to the bearing if I wouldn´t have the spacers I would had to change my rims. The only diff. is that I have the bigger drum brakes but it dosn´t seem to make more difference either not when you have that big wheels 39,5".
I am waiting for my order from frontrange offroad to arrive so I can install my full floating and disk brakes

I desited to go that way after brakeing a rear axle doing 50 m/pr h and loosing the tier not a plesant experience.
The axles doesn´t seem to bee any stronger in the longer housing at least by the look of them. and the housing looks the same streanght. I have actually seen more bent housing from the new housings than the old.

I am have problems with the housing warping at the bottom of the third member. Once it happens I can get a .040 feeler gauge between the housing and the third member. I tried to reseal the first one, but it only held fluid about half the day. I replaced the housing about six months ago and just had the same thing this past weekend. These are 94 model housing. I am running a V6 third. I am assuming that the torgue is forcing the third member up with enough force to actually pull the top of the housing back enough to create the gap at the bottom of the housing.

yea i think after 89 the housings were a thinner material

notajeep · « **Reply #19 on:** Aug 17, 2006, 05:18:44 PM »

I have the narrow housing and I had to have Allied custom build me some rims with 2" BS and I still rib the frame with my mad flex and 36" Iroks.

79coyotefrg · « **Reply #20 on:** Aug 17, 2006, 05:33:46 PM »

sounds like you need to buy my 86 housing
