Difference between firestone f9000 and f9100??

[83c10wit454]

I would like to know the difference between the firestone f9000 and f9100s. I recently got the 9000s for my c-10 and they look really small. Thanks for any help.

The 9100 is a larger bag with a greater load capacity. It also has a billet top mount rather than a composite.

The F9000 will do the job just right on your C10. They have a 1500lb load capacity per bag and are designed to be run at a 1 to 1 ratio... that means mounted off the axle and not levered.

We design all our rear kits with these bags as they yield the best ride quality, have a more consistent spring rate, and are easy to package into the system.

FWIW, I recall reading these were spec'd for GM pass car coil applications that needed a little more capacity. I believe the upper air fitting is also on the side of the billet end-plate for easier access vs the traditional top of the composite end-plate.

The 9100 is a bag that is made by ridetech for GM A body dirrect fit applications... The 9000 is a great bag.

Do you think the weight of my Square body blazer would benefit from going up to the f9100 ? I have the f9000 now and with the body on I sure cant get much lift .

The billet topped 9100 bag gets more total lift,... but ride height is almost the same because the 9100 bag has a taller minimum height.
5"-5.25"of lift at suggested ride height.
