96-Discovery Series I

I will need new coils within the next 5K miles, my question:

If I fit OME764 in the front and OEM763 + 1.5 inch spacer in the rear, would I need to replace the brake lines or swap the front drive shaft (to avoid vibration)?

You will want longer shocks if you do that and then yes you will need brake lines. As far as the D/S it should hang ok but keep an eye on it.

Your talking about close to 4" lift with that setup. You will need to address the front driveshaft issues at some point (ask me how I know, and what it cost me!).

FrankenRover,
I am curious now, how did you resolve the issue and how much was the solution?

 

[jcabrera]

As a follow up question, I now have 235/85/16 (with 1 1/2 lift & trimmed rear quarter panels), what would be the biggest size tire I could fit?

on a similar note....

i have OME 764's all round on my 90. it's pretty heavy (2300kg fully kitted out) and i find the 764's too soft.

what are peoples thoughts on the 763 Vs the 762? i was thinking on getting the 762's and maybe a 1" spacer under the back, but are these WAY stiff? would the 763 be better?

anyone tried 781's? are these still available?

TIA.

764's were okay spring rate on the front, but too soft in the back on my rig. It sagged pretty badly after a year or so. I went with some old 759's in the rear with some 2" lift blocks and it worked pretty well. With the 3-link and the 764's up front there is a moderate amount of body sway on the road.

My cost was related to the front shaft rear ujoint failing at highway speed, which allowed the shaft to smack a big hole in the auto tranny. Pretty pricey to fix. I knew the ujoint was going bad, but thought it would hold for a while longer.

that setup you list will most likely cause vibration as the others pointed out.

is there a reason you want such super stiff springs in the back? or just looking to get the most lift? since the springs are all about the same height. you wont get more lift out of them unless you compare loaded down rigs.

that setup is legit if you are aware of it's downfalls.

it's a good idea to do the brake lines if you go with the longer shock. if you change to extended lines be sure and place the plastic spring back on the Extended line that was on the original line. without it the extended line will have the opportunity to vibrate on the Rad arm and wear thru. i know of two people this has happened to.

since you have a rotoflex rear shaft you might not get immediate vibration from the rear but you are likely to start wearing out rotoflex doughnuts quickly and vibration to follow

last, you are going to notice your steering feels loose. this is normal with this much lift.

762's are a short, stiff spring. The lift comes from the rate, not the height. I would ONLY use them in the rear, with spacers, and loaded. They have a very tight coil/inch ratio, and do not move a lot. Empty, they will give 3 inch lift to a stock disco, and this has all been covered before, if you would only use the fricking search button.

Yeah, I have 781s with a 1.5" spacer in the rear (764s in the front - RRC LWB) They are still available - they're a DII spring.

The 763 is the way stiffer spring - if you always carry a ton a crap then that's the way to go.. 762 is very similar to the 781, maybe slightly less stretchy IMHO

sounds like 762's it is then. (i remember that i got confused 'tween the two numbers before! )

i DO carry a ton of crap in the back of mine. all the off road rubbish one normally has...ground anchors,tools,shackles,fuel,hi lift etc. i found that the stock 764 on the back would bottom out on the mildest pot hole!

vibs are no worry... got double CV propshafts front and back. this is the rig that used to have the long travel stuff on it, so it's still semi-set up for it. i just got fed up with the wobbly on road handling... and the fact that there ain't many rocks here in the UK to drive over! :flipoff2:

If you run mostly ruts and moguls, 762's are ok. However, it takes a shitload of force to stretch them. They are way tippy over non cross situations. They are probably the most stable spring to run with cones as they are sooooo stiff.

I'm currently running on my Disco the following:

Front OME 764
Rear OME 762 + 3/4" aluminum block

Not sure whether or not my Disco is considered light, but I have taken off the rear seats, no spare tire at all, and shifted all the weight forward of the rear axle. My waffles, pull-pal, spare axles, hi-lift are all flat in the rear footwells, which is actually great for the weight transfer. The 762s are a great spring...they are progressive, which helps a lot, and allow for a lot of articulation without minimizing stability. They are best used with stiff shocks (just changed from the N76 to the N29 in the rear).
