Outer Limits 4x4 Board

We want to lift my mates Disco 3". Just wondering what gear others have used and has there been any complications?

D1 or D2?

Series 1 update with twin airbags.

Front OME 764 rear OME 762 with 3/4 spacer
Front N73, rear N25 (or 29)

Does the D1 need X-member spacing, brake lines, ABS lines with that setup DiscoDino?

No crossmember spacing, but possible brake lines if longer shocks are used. The ABS lines are probably long enough so long as you pull them down a little.

Ihave longer brake lines due to the 2" BL and the longer shocks (mentioned above). Not sure which variable in particular needed these longer shocks, but it is VERY important to have longer/better brake lines.

Wellllll

At 3" I'd correct the castor. Either with offset bushings or modified radius arms.

If you go with longer shocks, you'll need spring retainers.

Make sure the front propshaft u-joints are perfect as this is getting near the limit of a u-jointed front shaft.

2" spring lift is much cheaper and easier.......

Personally, I think 764s are way too stiff for the front of a Disco. You would want to have a lot of eztra weight up there.

I find the same on the Rangie - 2 batteries steel bull bar and 8274 with steel cable and the 764's are still too stiff. I would try 180 - 220...

Remember it also makes a difference if you are too lightly sprung in the rear - A stiffer rear spring will make the front work more...

Being in Vic mate its pretty hard to go past Rangie spares springs.

You might be able to use stock rears in the front . If you want to know for sure, figure it out exactly. I have some nice newer more accurate data on the newer Disco rears. This would certainly be lighter than the 764s (and less lift). The older rears NTC5527 would give more lift than the newer dual rate jobbys NRC8044/5 but have the same normal spring rate. Otherwise the OME761s are good for the from with a winch and bumper.

LR Coil Spring Data

As stated, Rangie Spares has a better range selection (IME) and are cheaper. I'd call them up and talk as they have lots of real experience in seeing what works well in specific vehicles. They are certainly my first choice for springs (when I'm in your lovely Country).

The 764s ARE 220lb/in rated, the "correct" OME HD front 2" spring for rovers are the 751s which are 230lb/in, which are stiffer (by 4.5% ).

I said "Personally, I believe".... I've used 761s on a Stock Disco... They were too stiff. Those are 200 lb/in. And BTW, I believe the 764s are 240 lb/in. See my page. There is a lot of confusion over the rating of that spring.

Expedition Exchange have them marked as 220lb/in

Yes I know......

How about we stop arguing over ARB. Phone Andrew up at Rangie Spares.

1) They are 75% the cost.
2) He is open and honest about his spring rates.
3) He will be able to give useful knowledge of whether the fronts should be 180 or 220 lb/in based on what the ACTUAL Discovery in question is and what the ACTUAL owner wants with respect to softness/hardnees of the suspension.
4) He makes a wonderful selection of lengths in 180 and 220 ib/in..... Some of the longer ones are REALLY handy if you are putting in longer shocks.

Don't care what is says on paper - I used them based on the paper recomendation and they are too stiff

And I like arguing damn it!!!!!!

Bodge...If you're enjoying this, then I'll have to soil it for ya: "I agree with you"

Thanks guys.........looks like we'll be giving Rangie Spares a call. Might try Greame Cooper as well.
Next is the storafe system..........got to try and squeeze the Engle in.

Graeme Cooper sells the Rangie Spares stuff anyway.

Damn it!

I am off back to Pirate to argue about body lifts!!!!!

HAHAHA

Whatever you say, the BL has its use

If I remember correctly, it was a Dweb that the BL was fully trashed by the "special" people there.

Nah I am pro BL - after all I have one....

Interested in finding out ways around it without big spring lifts though...

If we are going to jack this thread lets do it properly
