Are front/rear disco springs quite a different height?

I imagine they are but no harm in asking before I pull her apart.

I have just received some Bearmach +1" springs from Rimmer Bros and they are quite a different height, not only that they are also differing colours (front light blue/rear dark blue) and the rears say RRC springs, the fronts are unlabelled.

I'm pretty sure they are the right ones but thought I may ask as they were meant to send me rear mud shields and they have sent me front ones so wondered if any more mistakes had been made.

Springs measure front:400mm/rears 450mm.

Cheers.

rrc bearmach or britpart springs are the same as disco 1,fronts are noticeably shorter

Fronts are shorter and narrower than rears

I thought they were different diameters but both front and rear measure 155mm, do you think they could have sent me a set of standard rears and a set of +1" rears by accident?
