Suspension different diesel vs gas?

[Dp578]

Hello this is my first post on this forum, so apologies if I put it in the wrong spot. I just got my hands on a 94 hdj81 and right away I could tell it needed some work, namely in the suspension area. It looks like the shocks are completely dead and I need to replace them. I've looked at a few shocks online but none of them remark if there's a distinction between the diesel and gas lc. I would assume the diesel is a bit heavier and requires different shocks/springs from normal LCs? Or do they both share the same suspension? If someone could please enlighten me, it would be much appreciated, thanks!

Toyota used different part numbers for petrol vs diesel.

Never seen any distinction made with aftermarket options.

I bought an HDJ81 with Dobinsons already installed.

First I swapped the left and right front springs because I think Dobinsons USA springs are slightly taller on the US driver's side - but with the driver on the right and a full size spare in the rear, it was sagging on the right side.

I started out with:
Front Springs: C59-166 - Linear Rate - 2.5" with Stock front weight
Rear Springs: C59-167 - Linear Rate - 2.5" with up to 220LBS

That was 22.5" hub to fender in the front. I didn't like the rake and suspected that I needed a slightly heavier spring to account for the diesel engine, dual batteries and intercooler. I don't think the springs actually gave me a 2.5" lift. Stock front end otherwise - no aftermarket bumper or winch.

So then I added a 20mm Dobinsons coil spacer up front that improved the rake:

That was just about perfect but I still wanted a little less rake. So I bought new front springs:

C59-170 Front Coil Springs | 3.0″ LIFT WITH 220LBS LOAD

I installed those and left in the 20mm spacer just to see what it would look like and I don't hate it. Might be too much reverse rake for some people. Now I'm at 24" hub-to fender. Hope that helps.
