Springs, Springs, Springs!

[BadCo.]

I have been doing some reading and fact gathering this weekend for when I replace my 27 year old stock shocks and super stiff springs.

So, I thought I would share the information with everyone else, and maybe get some help filling in the blanks and opinions on weight loading. I am waiting on a reply from Dobinsons and King Springs to fill in their blanks.

The most important ones I am missing are the stock Perentie Springs. Anybody have the details about them? Its too cold and wet to go outside and pull the springs out of Hank.

A little snippet here:

110 Perentie
Perenties run different shocks to civilian spec vehicles. BYG4001 Front and BYG4000 rear, 4x4, 6x6 and RFSV to match spring rates and ride height. SRV have different again due to fade through heavy use.

I was thinking 250lb springs for the front and 300lb for the rear, which would be the OME 766 and 755. I don't carry a lot in the rear, just the usual tools and recovery gear. A false floor will go in later too. Maybe I could drop to the OME 752 progressive springs?

But it all depends on what the stock springs are...

Let me know your thoughts.

Hey mate you have the 4 door version don't you? If so you'd have more in common (weight wise) with a standard county than a rag top 110.

On my civ 110 I went with LRA White Tiger Orange / Yellow Coil Springs 270lbs / 16.8inch length on the rear and White Tiger Purple / Yellow Coil Springs 220lbs / 15.5 inch length front.

Works out as a small (50mm) lift with winch bar, high mount, etc.

Hey flagg, thanks for the reply.

How do you find those springs on and off road? Is the 220lbs in the front enough for the Isuzu? How much weight do you carry in the back?

I think the Perenties sit a bit higher then Counties, so I really want to find out the specs of the stock suspension so I have a starting point.

I find 220 perfect with the Isuzu, heavy bar (the winch cradle is made from 1/4inch plate) with brush guards, high mount etc.

I don't carry huge weights.. as little as possible really but I would definitely use these rates again. I measured my heights when fitted and between the centre of the axle and the bottom of the flare on each wheel is between 540 and 545mm.

Did you ever find out the data for the perentie springs?

I note that the data book gives a loadspace height of 825 unladen and 710mm laden

So 115mm with 900kg = 4.5” with 2000lb, 1000lb per side is 220lb/in
