Bilstein B8 6112 & 5160

I wanted to level out my new truck and improve suspension response, so after doing some research and decided on Bilstein 6112 and 5160.

Should i have any concerns about spring rates ? from everything i could find online they are somewhere around 600 lb/in

I did a-lot of research about our factory spring rates, didn't find much other than;

Spring Code: VVCC ( couldn't find this lbs/in reference anywhere )
Front GAWR: 3900lbs

My thoughts are when you increase the preload on the supplied Bilstein spring by moving the perch up, you are effectively increasing the spring rate if its linear wound. So by moving up the perch from the 0" to 2" i am hoping the effective rate is somewhere close to factory for the diesel front end weight..

i asked the vendor to clarify these points before shipping, i will respond to this post with their answer.

My previous high end shock experience is with Koni RAID's on my Nissan Safari, these are absolutely brilliant and if offered for F150's i would defiantly go that direction but unfortunately they are not.. next best option for me is the Bilstine B8's which are on special for Canada Day.

I will post pictures and review when they arrive..

Nope, I have used and read rave reviews about Bilsteins for years, good choice!

Oh and setting at 2" will be 2" higher than front end is now.

After doing some more research they seem to be 500lb/in in the 6112's which are fine for the 449lb 3.5 eco-boost and 444lb coyote v8.

our 3.0 PS engines weigh in at 501lb


my first thought is 52lb seems insignificant and these should work.

If you are worried about weight. Look at AutoSpring, and leaving the Bilsteins at 0" lift, and using the AutoSpring spacer to get the lift. They do the same thing.... I have ran both since 06 in F150s and they have all worked just fine, zero issues.

Just an update; these have been backordered for the last month and i expect them to ship mid August. I have picked up some BFG KO2 285/65R20 which i will install in the fall after i get the Bilstein in.

I know this is more of a F150.com question but i will try anyways.. Do you know if I can run 285/65R20 KO2 with 2" lift and 1.25" wheel spacers and Gatorback mud flaps or do i need to order the setback type ?

i ordered BORA 1.25" spacer and Gatorback FX4 flaps
