BDS Spring Rates

[colinmacdon]

I talked with a tech from BDS suspension and he mentioned that the spring rates for the 2" lift, are 450 lbs for the front, and 210 lbs for the rear. Doesn't this seem like a huge difference? I thought Rusty's coils were like around 300 lbs all over and the OME are 350 +lbs.

Mmmm, interesting. These are exactly equal to the spring rates of my King Springs (front KJFR-27HD: 450 lbs, rear KJRR-28: 210 lbs).
Could the BDS springs be produced by King Springs?

The front springs are bearing roughly twice the actual weight, because of the leverage in the geometry of the front suspension. Hence these springs are about twice as heavy.
