Have owned my 2004 HSE7 Disco for a month or so now and have installed the 180 thermostat and changed SAI solenoid and done all fluid changes. I then promptly purchased the 3" Terrafirma kit with extras (from Lucky8) to convert from air-bags to coils. Kit included springs/shocks and sway-bar links as well as spring plates and spring retainers for the rear. I also purchased the Terrafirma steering Damper to get it all done (I've previously done a similar lift on my 2001 but all OME, wanted to try a cheaper route this time).

Tried to do the steering damper last weekend, cant get those bolts to shift..so tried the lift starting with rear-drivers side first. Couldn't get the axle down far enough in my driveway to even think about getting the coil in, packed it in when I realized I wasn't getting anything done without spring compressors. Did get the old shock out though.

Took another stab at it today, cut the sway bar links in the rear...I know, but those buggers would not move and I have the Two that came with the kit, although I admit to not knowing if they are for front or rear With the help of a neighbors 3-tonne floor jack I got it lifted enough to throw the bottle jack between axle and bump stop and get that spring in (on top of the newly fitted spring plate which I had to wrestle with too, those bolts do not go in without an impact gun).

Issue #1 - Forgot the Spring retainer plate...Guess, I'll have to forget the other side too...Big issue? My offroading is light not really rock crawling.

Issue #2 - Spring in, shock on, wheel back on. Not seeing a tonne of lift yet, it's only the one shock/spring but I don't see how my new 32" A/T are going to fit under there..

Does it just need to settle or does something look off, other than me not finishing the other three shocks/coils?

 

I normally use a couple of ratchet tie-downs as spring compressors. I would jack it up again and try to pull the spring tight enough to get the retainer plate into place.
What are your plans for turning off the air springs in the SLABS unit?

 

I didn't have any, lol. The air-bags are out (obviously) and the air tubes are sitting on top of the spring plates, why do I need to turn off the air? Will it throw codes?

 

I use the red LR bottle jack between the axle & frame. Coils will drop right in F/R.

 

The compressor will run non-stop since the sensors are going to be sending inaccurate info to the SLABS and the truck still thinks it has to adjust the bags. Pull the relay for the compressor, and then find someone who will lend you a Hawkeye to reprogram the SLABS as coils instead of air.

 

What best said ^


And heelllllll no! Ratchet straps as spring compressors? I won't hardly use the real McCoy. That's just asking to get killed. No need to use spring compressors at all.

 

I use two military cargo straps that I ratchet down on both sides of the spring at the same time to compress it an inch or so.
It's a 2 man job and a bit ghetto but it works.

 

Hi there - that does not look much different from my 04 stock - assuming those are 16 inch rims.

Join Roverlanders BC, they have fairly regular events. Founders day on the Apr 14th weekend in Chilliwack,you can at least talk to other disco owners and commiserate

Hit Andrew, (ACG) here with a PM I believe he has a navcom

 

Got it all figured out, thanks everyone! Rubber (Wildpeak ATV3 32”) goes on today! Will update with images once done.

 

This is how mine looked with the TF 3" lift and stock 29" tires. Yours looks like it's not HD springs. What are the part numbers on the springs?
