BDS spring rates

[sreidmx]

Did some research, called BDS about some springs I found some interesting info that contradicts the spring rate table.
Here are the part numbers,
Part# Rate Vehicle
004402 – 550 Jeep J10 4 inch Stiffer later in travel more arch than 6 inch lift spring on a chevy more like 6-7 inch lift.
001401 – 575 Chevy front 4 inch Stiffer sooner in the travel
001551 – 550 Chevy front 6 inch stiffer later in travel. this is technically a 5.5 inch spring.

These are rear spring rates I assume?

WOOPS!!

WOOPS!!

Actually, I originally thought that the springs on the CK5 spring rate table were all front springs but the last that says 56 inch. Was searching for part # for the TC and could not find the # on the TC web site so they must have new part #. Quite some time since the spring rate table was originally written ,so maybe BDS has changed the spring rates?

Possibly

No they're front..

They told me the rates can vary based on production variances. Standens in Canada makes them, their good springs.
