Spring load and the math.

Springs

How to determine load by rate quickly and simply.

RR Load

RR Load: 375

RR Spring rate: 225

Height: 13" free

Load / Rate = Load (375/225=1.650 or 1-5/8)

Free height - 1.625 ' = compressed height

13" - 1.625 = 11.375

At 11.375, you will have a spring load of 375 pounds.

This needs to be at ride height.

LR Load

LR Extended Load: 185-225 pounds

LR Spring Rate: 125 x 16

Free Height: 16"

Load / Rate = Compressed Height

200/125 = 1.6"

16 - 1.6 = 14.4 or just over 14-3/8"

When setting the load on RR, you need to be at ride height and the car setting on the ground. You can do this with or without a driver; just do it the same way all the time.

The LR needs to be set with the tire just hanging or just off the ground. ( on the chain)
