I just called comptech because one of the tags was missing on one of my springs. The guy told me that the spring rates for the front were both 255 lb. , but the tag on one of them said 251. Did I get the wrong springs?
Everything I have read on this forum said the spring rates were different for the left and right, both front and rear.

Even the instructions say they are different for the left or right. He also said the the front were linear and the rear were progressive. I thought the front and rear were both progressive. Please help me.

 

Hasn't Comptech given you the info you need? The fronts are not progressive - why would a chat room give you better info than the source, I wonder?
