Should 3 month T. Dog 2" Progressive Coils look like t

[gotoy]

Yep, this is 3 month old T. Dog Progressive coils. I have winch installed. All 4 coils are like this.

Your comments/advise most welcommed.

Im not a fan of T dog stuff. A friend had Tdog foam cell shocks on his navara. dead in 40,000km. My hilux has 200,000km + koni's under it and still going strong. Havnt had anything to do with there springs thou.

Don't quote me on this but I think this is normal. At least this is what ARB told me when this happened to me. I think the idea is that you get extra down travel if you have longer shocks.
In theory you get a softer ride and if you have a load than the stiffer part of the springs take over. In practice this isn't usually a big success because by the time the stiffer part of the spring takes up you are sagged heaps anyway or in your case the extra soft part of the coil only helps in down travel.

The problem I had was that I got too soft a coil and within a few months I was back at standard height and I didn't have more down travel because it doesn't spring back with the weight of the car compressing them constantly.

The guy at ARB did tell me this was going to happen and didn't want to sell them to me but I wanted more flex and that was that.

I am by no means a guru on springs so take my comments with a grain of salt. Guru status will come in a few years time.

If u are reffering to the coil stack at the top, the springs are designed like that so with long travel shocks, at full hang the spring is still captive. Thats the only reason they are made like that, those coils do nothing under normal driving, dont limit up travel, only keep spring captive at hang.

i thought that with progressive rate coils the top few were closer together, than the rest, but no where near touching, i thought it would be bad for the coils to be constantly rubbin on each other all the time.

My Hyundai CrapBox (Excel) has progressive rate Kings in it, and the top few coils touch in it, it is normal.

I would say with a 4WD having a lot more movement, i.e. down travel, it is only normal that more coils are stacked so that the spring won't fall out upon full droop of wheel (extension of spring).

I like the idea of progressive rates, a much better working spring...

WHAT'S THE POINT IN THIS TYPE OF COIL.
Travel is generally limited by the shock not the coil.
This type of coil does not allow for the use of a longer shock.
Nothing gained.

[Meldge]

With this type of shock when buying them they are normally for a lift, are they not?

This should provide a slight lift allowing a slightly longer shock to fit, and that shock will allow more droop. The stacked coils at the top will separate from each other when needed, leaving the first and second coils the last to come apart. In doing this, it allows the top of the coil to stay in its seat and not 'fall' out of the vehicle...

Thats the way I see it anyway...

I understood that progressive coils were so that you got a soft ride when empty (Rides on the top part of the coil that seems to have sagged in those photos) then, when you carry a load, the stiffer bottom section helps by carrying the weight.

Look around at TJM sites and stuff and I'm sure that's where I read it.

I think the obvious question would be, did they look like that when new? Or in other words, does it still have 4" 's of lift?
They look similar to a progressive rate car spring, though the top coils don't actually sit on each other that much, they are just progressively closer as it gets to the top.
