Question:

2021 Expedition Limited. Your website offers CSS-1094F and CSS-1168F. What is the difference between the two? Im thinking one is for 2wd and the other for 4wd? But the website shows both will fit my 4wd vehicle. Thanks Neil

Helpful Expert Reply:

Though both the Coil SumoSprings # CSS-1094F and # CSS-1168F are listed as fitting your 2021 Ford Expedition, there is a difference between the two. That being the height of the spring.

# CSS-1094F - 2.25" tall
# CSS-1168F - 3" tall

The # CSS-1168F will fit both 2 wheel and 4 wheel drive models, but the # CSS-1094F will fit only the 4 wheel drive models. You will need to measure the gap between coils on your springs to make sure which would be the better option for you.

Is the spring gap supposed to be measured while compressed under load, or are we supposed to raise the vehicle and measure when the spring is extended?

@Clay Good question. You should measure when the vehicle is not under a load (so no cargo or trailer attached), and when the vehicle is on the ground (so not on a lift or jacked up on stands).
