I'm asking because my fronts are blue(haven't checked back) and it just seems kinda odd. I have heard of some sort of blue spring before, but there's no way these springs are by any means tall.

 

DAP sells a blue spring which I do not recommend to people cause of their lack of any exposer to rough handling and see how they hold up.
What do you have for shocks and why are you asking, are you looking to lift the truck?

 

I am going to be lifting soon, I just thought it was weird to have STOCK blue springs. I found out when i was doing brake work and rubbed a little of the dust off the spring.

I cant see these springs providing any lift, I mean my truck is low.

 

stock springs are mud and rust colored, possibly red clay colored depending on where you live.

 

The stock springs are black and have colored dots on them to indicate spring rate. If they entire spring is blue then it is an aftermarket spring.

 

Ok, im on crack.

Id seriously reconsider any advice you guys take from me. I went out and checked. My springs are black.. The drivers side just had some blue stuff on it, dont know why or how.

 

The "Big Blue" springs that AB sells are made by Maybach and are one of the top used springs in the UK.
They are the ones I am going to get because they are HD but offer no lift.
