They are supposed to be the same height front and rear, just like stock.
Youtube Lucky8, they will show you the 4 +2" Terrafirma springs, and tell and show you they are the same height.
And that the way to tell front from back is the thickness of the lower coils on 2 of them.

 

OK, so give me a little slack because... my first Rover and I've only had it about a month. Haa.
After asking around everywhere, someone finally asked me if I had lift blocks on my rear. Looks like the answer is quite evident. Oh boy.....

 

Spring Spacers.....mystery SOLVED!

 

Now, if we can only get that bigfoot thing solved...we'd be on a roll...lol.

Glad you got things figured out.

Brian.

 

At least you know what is going on. Not sure how thick the spacer is that you have back there but you could do similar in front. But then you need to consider the driveshaft and other issues. I have installed the same kit on mine but added spacers in both front and rear along with driveshaft, brake lines and rerouted ABS cables.

 

So, this is what I took out. Two 1.25" blocks of wood. Homemade. Thinking of replacing with a 1/2" spacer.

 

Awesome...put those in the classifieds

 

Wonder if they are trademarked. I think I could reproduce them. Haa

 

WOOD, that's a new one. I've seen hockey pucks, but wood... not so much.
You can buy aluminum spacers for about $45-60 ? > Suspension Lift Spacers - 1 Inch - Rear (Pair)

OR, if you really want to make a set of ANY SIZE you want for less than about $30.00 go here > https://www.onlinemetals.com/
They will cut small lots of any material including aluminum cheap.

 

You could do the D1 hats to gain that 1/2” or you can do the same thing with 1/2” alum spacers. If you need some alum spacers: I have 1/2” 6061 alum at the shop and can make a set for you. Already have 1”, 1.25” and 1.5” made.
