Suspension upgrade advice

[DJD120GXL Senior Member Find all posts View Profile Close DJD120GXL]

Hi PP,

Looks like I'll be finally getting around to my lift, with all the stuff ive done it should have been earlier but finally its time..
I was carrying way too much for the recent Fraser trip and was bottoming out on a few cut up inland tracks, loaded up I must have been super low but that's another story..

at present Ive got the works up front and DIY drawers with 100KG+ in the rear im currently sitting at:

FL 725
FR 725

RL 735
RR 738

*sadface

Ive been looking around for a while and I'm almost settled on US Bilstiens 5100 front and rear or 5160 in the rear if i can afford it.
I plan to import them, and buy some Dobbinson coils from #### in Vic. Im also going to do the upgrade myself, likely to remove the whole struts and take it to a mechanic to set the new completed stuts up so I dont need to go down the spring compressor route.

(I know there is a thread on an in-car strut removal without the coil but im not confident I can do it) might just make it easy and drive the completed strut over for the change over. safer too.

my main questions regarding the purchase are not about the different products or the install, that will come later no doubt.

what I want to know is when doing the upgrade should I do any of the other mods at the time to save me doing it again or can they be done later easily, things like. Diff drop, extended links, spacers, airbags etc. keep in mind im doing it cheap but if its significant I'd do it to save time.

I'd like to get a maximum lift so things like UCA upgrades are not out of the question but will more likley be down the track.
I guess I dont really know the geometry of all things suspension so I dont know at what point I need the links, spacer, or diff drop and at which point I can run larger tyres.

Should I start at the middle cir-clip slot and what should I be looking for when I am deciding where to let things sit?

lots of questions I know, but if there is any advice Id love to hear, last of all Ive only considered dobbinsons or king springs. any major difference?

Cheers

There's nothing else you need to do really that's worth while really.
If you tow a bit & it's a heavy download you might consider throwing airbags inside rear coils, not hard to do later either. Maybe c how u go first.

You will get a huge lift when you combine 25-40mm you have dropped to a 40-50mm lift.

Thanks, I think I'lll just start simple. do you mean I'll get a total lift of 25 + 40mm or will it only be 40-50mm on my current ride height, I cant work out which plays the more important role in the height/travel the springs or the shock.

You will get up to 75mm at font & 80+ at rear based on those measurements you have posted.

I'm really happy with how the US spec Bilsteins (5100 and 5160 series) performed over the corrugations from Coober Pedy, William Creek and Marree via the Oodnadatta track.

What height are you sitting at Andrew and how many K's have they done?

Roughly 800mm front, and 820mm rear. It's on for nearly 2 years now, so about 30,000km.

Thanks mate, what groove to you have the cir-clip in? and If I went for C59-317 which groove would be best to start with, I'm unsure about the measurements and how they coexist.

I'm on the 2nd groove from the bottom. I'm not sure about the C59-317 as I can't see it in the suspension database. I would put it in the bottom groove to start.

Googled and found that the C59-317 is a rear coil for LC 80 & 105

my apologizes, I was getting the 7 mixed up with the 327, I meant 314. (going 327 for the rear)

Linear Rate
Raised Height (45mm Lift)
80-150Kg Accessories (Bull Bar and Winch) 1 C59-314

Bottom groove (maximum spring length here too?)

Also can you post the link for your Diff spacer.

Yes, bottom groove. The bottom groove is meant to replicate the factory's bottom seat position.

Diff drop spacers is in the bashplate thread http://www.pradopoint.com/showthread...-made-supplied

Has anyone installed 5100 front and rear? Looking at them now as 5160 are out of stock for a month or more, been on back order since early 2014. Apparently there is a new model number coming.

[DJD120GXL Senior Member Find all posts View Profile Close DJD120GXL]

Decided to go with 5100's all round, will report on them when installed.
