REMEMBER THAT THE COIL SPRING RATE DOES NOT DETERMINE 100% OF RIDE QUALITY!!! IT VARIES GREATLY BASED ON THE SHOCKS YOU RUN!!! NOT TO MENTION CONTROL ARM ANGLES!




-I have an ongoing list going at the shop, if/when I get more info on any available coils and the spring rates I will update this thread with the new info.

I don't understand what it says.  Does a higher spring rating mean that it is a stiffer spring?

Yes... a 100 pounds per inch spring will need 100 pounds of pressure (weight, bump, etc.) applied for it to compress one inch.

Progressive rate springs start compressing with a lower rate (pressure) and it ramps up to a higher, firmer rate.
