I drive about 40% highway, 45% city, and 15% off-road. I would like to run 265/75 tires with a new lift. Who make the best lift for this situation? I don't mind triming a little, but i would like to keep driveline viberations to a min. Thanks for you input.

Which ones better ? Hmmm , I think thats in your mind really. A spring is a spring is a spring , its just metal and isnt really unique to any specific vendor (aside from slight rate differences) as they arent even making them . The springs by themselves do not have any magical powers and having one over the other (Same lift) wont enable your truck to do spectacular things off road . In the end it comes down to price , durability and longevity. Some dont mind dicking around with springs and suspension constantly. I would rather just put them in and forget about them..
As far as the vibs are concerned , well , just get comfortable with the fact that you are gonna get them and then do what ya gotta do afterwards to make them go away. If somehow you dont get them you will be pleasantly surprised..

i have DAP's Big Blue Monsters and i agree 100% with kyle. they all work, they all do the same thing. its a matter of how much you want to pay and how long the things will stay "sprung". so in my humble opinion its a matter of dollars and sense. as far as viberations. i have an alleged three inch lift and have to date NO viberation issues. so it comes back to some disco vibertae some dont. just keep it well lubed.

"i have an alleged three inch lift and have to date NO viberation issues. "
Mike, what are your measurements from center of wheel to fender lip...just curious.

ok since you have no VIBs what have you done tp rpevent them I will get a rover in the near future I think and will be getting the RTE 3" and a rack will prolly be all the mods I do maybe a RTE bumper in the front...I am trying to get as much knowlege about ROvers and all before I sepnd all of my money on it...your discussions have been very helpful....

By Eric N (Grnrvr) on Sunday, December 09, 2001 - 02:29 pm: Edit

With suspension it is hit or miss.. Not every rover is the same. You could get a 3 inch lift and not have any issues or you could get a 2 inch lift and have big issues. It's one of those things that you won't know about till you just do it.

By Phillip Perkinson (R0ver4x4) on Sunday, December 09, 2001 - 02:30 pm: Edit

I think that is rather interesting..Why do you think it varies so much from truck to truck

By John on Sunday, December 09, 2001 - 02:34 pm: Edit

Phillip, On 3" lifted vehicles you are dealing with a suspension change which ups the ante on getting into driveline angles which are incorrect in the geometry and may cause vibs. In Rovers some have problems at 2" and them some go 3" with no problems. Just like height measurements after springs, there appears to be variences in these basically " individually" built autos in many different areas. So in individual trucks the cause and effect in lifts arent allways the same. We have done 2 body lifts on 97 Discos in which simple things like A/C lines are run differently resulting in different radiator mounts, little variances in similar year autos. Its a see when you get there thing that have basic rules with big tolerances.

I have two trucks here with close to three on each. One has vibes and has better drive shafts. One has no vibs with everthing stock... Its a crap shoot..

Kyle

By Phillip Perkinson (R0ver4x4) on Sunday, December 09, 2001 - 02:37 pm: Edit

so in your opinion what would be the best year disco to get if I wanted to lift 3" how many trucks do you know of have had many issues with it or is like you said it just varies and there are exceptions..I do understand the whole geometry and all..........I hope I get lucky..

By John on Sunday, December 09, 2001 - 02:45 pm: Edit

I hope I get lucky..
97 or later,IMO.

By Kyle on Sunday, December 09, 2001 - 03:00 pm: Edit

The one here is a 95 and has the stock Rotoflex rear. The truck needs to sit a little high in the ass...

Kyle

By John on Sunday, December 09, 2001 - 03:06 pm: Edit

I have come to an opinion that the vib variations are largely created in the TC case in use of particular shaft brgs which may vary in make or tolerances...Not all the time, but more than we see. Just an opinion.

By Phillip Perkinson (R0ver4x4) on Sunday, December 09, 2001 - 03:11 pm: Edit

I see...what makes the vids..are they really that bad? or just more of something to bother a person... my buddies jeep has a 2" shackle andyou can noptice some vibs there...but anot her guy i know has a 4" on a cruiser and it doesnt vib

By Kyle on Sunday, December 09, 2001 - 03:21 pm: Edit

Yes John , the later transfer case he much less slop in it...

By Eric N (Grnrvr) on Sunday, December 09, 2001 - 03:23 pm: Edit

It depends how bad the vibe is.. When I went to 2 inches it wasn't that bad but, I figured since I was already getting vibes might as well get the 3 inch lift. Put on the three inch lift with DC front shaft and had really bad vibes. Got a new rear DC shaft and they got a little less. Put and extra 1 inch spacer under those 3 inch springs to fix the pinion and drive shaft angle and I have almost no vibe at all. I don't think that my drive shafts are vibing right now. I think that I have some thing else wrong that is causing something to shake around since I mostly feel it in the steering wheel and not in my seat. Mines a 98.. So John, having done two body lifts already you want to do a third on a 98?

By Phillip Perkinson (R0ver4x4) on Sunday, December 09, 2001 - 03:27 pm: Edit

So if you only had enough money for one drive shaft which would be the best to replace or does that vary too??

By Kyle on Sunday, December 09, 2001 - 03:28 pm: Edit

The front is shorter and suffers more....

john,
sorry for the delay my wife has had recent surgery so i am in and out of here. i measured from the bottom of the upper spring rest and the lower spring rest on the left frt wheel. the reason i measured the front was because i was under the impression that the front was the heavy end of the disco. there is a reason for the word alleged. i measured several times and with the avg of the left frt wheel i came up with 2.5 inch of actual lift with the weight of the vehicle resting on the ground. DAP adverstizes its lift a 3". a half inch variance is not really that bad. the other aspect of my figurin was the actual height loss of the stock springs. this is were my scientific reasoning leaves me. my firgures for the stock springs are not altogether accurate because i measured the springs with the wheel off and the spring slightly relieved. so in conclusion based upon the my attempt to be accurate and allowing for kentucky windage and that adverstized height of the DAP springs i feel safe in stating the the actual lift was somewhere between 2-3 inches, but it could be 2.5"-3.25". or it could be somewhere in between. as far as the luck with no viberations, i give most of that to the age of the vehicle and the previous owner(s) care and repair of my 94.

By Eric N (Grnrvr) on Sunday, December 09, 2001 - 05:13 pm: Edit

I'm wondering if my problem is that not only is the drive shaft to pinion angle off a little bit when looking at it from the side, but, if you look from the bottom of the truck up the angle is off a little there too. The pinions and the trans case don't line up perfectly so I do have a compound angle going on. But, the closer I get them to matching up when looking side ways the better the truck feels. Don't know what to do about the other part though. Would be a little hard to move the transcase wouldn't it? I think that I need to get my bushings in the radius arms replaced though. My steering wheel is shaking over 40mph and when ever I go over a bump like a speed bump the front just doesn't sound solid. It sounds and feels like some thing is loose up there. I checked all the bolts though and they are tight. Would a bushing do that?

If you dont fix the vibrations what will they do

By Eric N (Grnrvr) on Sunday, December 09, 2001 - 06:31 pm: Edit

Cause your U-joint to go bad.. Worst case would be if your u-joint fell apart while on the highway which could cause your drive shaft to stick in the gound and make your truck do a 60mph pole vault. Would probably wear out things in the transcase and diff faster as well. That and your truck will ride like crap. Gas mileage will be even worse.

ok I see now..I dont even think I wanna lift my truck after this disscussion

phillip,
dont be so afraid of what may happen if you lift the truck any alterations will effect your truck in some way. the most important aspect of any change in the OEM design is to understand that you will have to adjust B if you change A. this B can be anything from a mechinical part to how you drive. ask yourself exactly what is the final product you are wanting and then get your checkbook out. good luck
