I appreciate any feedback as I recently had an ARB rear tire Carrier added to my newly lifted 2003 LX 470. Since I picked it up, I could feel a lot more heaviness on the backside almost like I was being pulled backwards as I drove. Strange feeling. I believe the guy ordered the dobinson lift with medium shocks for the back and said that would be enough to handle the extra weight in the back. Trying to figure out what I should do to better balance out the weight more proportionately fit a better ride. Take off tire? Add heavier back shocks? Thanks for any help.

Put some armor out front
I think an HD pair of shocks at the back would help, lessen the rebound from that now loaded rear.
Most definitely, unless of course you want to carry 2 spares.
I am in a similar boat as you. I have approx 400 lbs of extra weight.
I paired it with the OME 2865 ( I think ) which is rated for about 220lbs. The truck is at about 20" ride height and has a very boat like feel in the rear. The springs are hurting for sure, the truck rides like crap right now, very rough and I feel every crack in the road.
I have an order in with @crikeymike for the 400lb contstant load setup
Shocks-GS59-682

>> This will provide the ability to hold the extra weight without lifting it much.
Will report back once the coils show up.
You've also moved a 90 LB wheel and tire from under the truck to 12" behind the rear bumper, which is a move of about 40" (3.33 ft) and that translates to about 300 LB-FT in torque from it's original location, so it gives the impression of much more weight than it's original location.
I carry a 125 LB wheelchair rack on the back of my 80 most of the time and it is a HUGE difference in driveability, not to mention what it's like when the 400 LB wheelchair is loaded. The COG of the wheelchair is about 24" past my rear bumper. Adding the weight of the chair and the rack together out there, it's like an interior load of almost 1000 LB.

Just took it over to a friend that I did not realize does lifts and modifications. He took one look and said he could tell it had a little sag and to go ahead and get the 440lb load springs. He said the weight in the back would balance out any extra stiffness from the new springs.

He also said the LX470, which he loves, does not have a ton of power to handle really heavy weight and any mods should be on the lighter side. Which I can confirm since I lifted with 33 tires and arb carrier does take a little extra time to get going on the road. He thought mine were light enough and just to add the 440 springs.
I agree. So you are in the same position I am in.
What I noticed is most aftermarket springs that can support that weight will also give a 2+ inch lift. This translate to the stink bug look and poor handling, so now you go down the rabbit hole of lifting the front to balance. Dropping your diff, extending your sway links, and then shoot might as well buy some over priced huge tires.
The best solution I found was the C59185 Dobinsons to support the weight and only add a small lift, allowing me to keep my stock front end.
19-19.5” is stock height for the front. 21.5” is lifted a little over 2” for the front. Rear is about 20-20.5” stock. 22-23” lifted on most rigs, when using the proper springs for the weight you’re carrying.
Good info , thanks
