What's the prefered front springs fort our 2 wheel drive trucks ? Variable or constant rate springs.

 

.. not to be nitpicky but the correct terms are "progressive" and "linear" rate springs.

Who offers progressive coils for these rigs?

 

Moog has had them for at least 25 yrs

 

I put some moog progressive on about 4 months ago, got them at napa. I'm not saying they are bad springs I just like a stiffer ride. My truck is a 70 lwb may ride different with a swb. They ride ok but wish I had gone with a heavy duty spring.
