Short HD OME install and review..
Just for those who were wondering I only had it for 1 day so far.
But it was quite simple.. Id recomend doing front together and back togegther but some people do it side by side.
I already had my sway bars removed, so Im not sure how they would come into play. I dont see them changing much.
Im only writing this for people who may think this is more than they can handle.. It took me probably 3 hours. And the tools needed are minimal.
----------
Basically all you need is..
-19mm Speed Wrench to remove shock [regular is fine, but it will take you a while]
-13mm ratchet with extensions [remove shock mount.]
-17mm speed wrench and pair of channel locks [or second 17mm wrench] to remove rear spring retainers.
-Pipe or strap wrench to hold shock in place.
-Floor jack is much easier and safer.. Desperate people can use bottle jack and bricks or wood [dangerous.]
-2 jackstands or agian you can use blocks and wood but.. dangerous.
To install springs its helpful to have a second person.
----------
To remove front:
-Lock Center differential, and or chock rear wheels, place in park and pull emergency brake
-Loosen Front Lugs. I use 1 1/8" socket
- Jack up axle. Its hard to place a large floor jack in the center of the axle due to the differential. Placing slightly to the right [close to center] is fine, one side will lift a little higher/sooner than the other.
- Place jack stands under frame
- Remove wheels and slide under vehicle for extra safety
- Remove one 19mm NUT from axle shock mount. Using pipe wrench to hold in place.
- Remove air filter box/maf sensor to access shock tower.
- Loosen 4 13mm bolts around shock tower two from engine bay two from wheel well.
- Remove shock tower along with shock up through engine bay. Try not to loose the lock washers
- Disconnect ABS wires [connector is mounted in engine bay ontop of wheel well]
- Lower floor jack/axle keep an eye on the brake lines not to over extend them but fronts shouldn't be a problem.
- Give a little tug on springs and they should come right out. Remove both sides. Shock Tower retainers should come out with springs
- Grab new springs [OME are marked for front/back passenger/rear]
- Place shock tower retainer back in position and use two nuts to hold it in place.
- Put new springs in place, lower axle as low as possible without extending brake lines and they should go in easily.
- Installation is reverse of removal.
-----------------------------------------------
To remove Rear.
- Jack up axle. Its hard to place a large floor jack in the center of the axle due to the differential. Placing slightly to the right [close to center] is fine, one side will lift a little higher/sooner than the other.
- Place jack stands under frame
- Remove wheels and slide under vehicle for extra safety
- Remove one 19mm NUT from axle shock mount. Using pipe wrench to hold in place.
- Lower rear axle untill it is hanging [rear springs take more effort]Watch brake likes for now keep a little slack
- Remove two 17mm Bolts/Nuts using 1 speedwrench and 17mm wrench or Channel Locks
- Remove spring retainer
- Remove spring with isolator and lower...part
- Place spring isolator on new spring.
TIP. I took two wood clamps
And used them to compress the spring slightly. Very slightly
- Lower axle as much as possible brake lines will get pretty tight.
- Place lower.... part back on axle
- Put spring top end in first
- I needed a friend to step on the axle to give it that much more room to get the spring in. Brake lines were VERY tight.
- Remove wood camps
- Installation is reversal of removal.
Only part I needed someones help was to align shocks while raising axle and push down rear axle to get new springs in.
Installing shocks is self explanatory
---------------------------
Drivers side rear 34 1/4" +2.5
Drivers side front 34" +2.25
Passenger Side Front 33 3/8" +1.6
Passenger Side Rear 33 1/2" +1.75
With Drivers weight front drivers side lowers 1/2 inch.

Review..
Anyone who ever said this ride was too stiff. Is wrong, and probably never experienced it. Dont bother with the medium suspension. This ride is perfect. Only thing I can see making the ride harsh is HEAVY duty shocks. I used stock shocks and honestly MIGHT replace them because I removed sway bars. If I still had them There would be no reason to. Ride is NOT bouncy, and passes the rocking test. Maybe for longer travel? I haven't maxed out the shocks yet...

What brand of coils did you install, who's shocks?
You always use HD shocks on a Disco to help control the top heaviness. It is too bad you used factory shocks, they are the worst just under Pro-Comps, the 2 shocks of choice are OME and Bilstein.
I may be confused, are you saying since your sway bars have been removed, you might also remove your shocks, please clarify.

Ill get around to shocks, but I was saying I don't see them as CRITICAL if you have the sway bars still on your vehicle. I was saying I would get some shocks to help with some highway "sway" and to hush some people up.

I was about to clamp off the brake line and just disconnect them. I have done that before.. Simply bleed after, no issues.

I know when I installed my lift I never took the shock towers off. I just jacked the axle down far enough (i was installing new brake lines so they were removed) that I could unbolt the top and bottom of the shock itself and remove it with the spring. I never did one on the ground so that might not be possible????? Plus I was installing OME 764f an 763r that would equall about 3" lift I measured that day it only lifted about 2" a week later I measured it raised the truck about 3 1/2" im still trying to figure that one out.
