Bilstein 7100 shocks in Minnesota
I've got a set of 2 Bilstein 7100 AK7112R04 unused that I'd like to sell.
Specs on them are
19.53 in Collapsed
31.1 in Extended
255/70 Valving.
Bilstein 5100s are is 17.68 collapsed, 28.9 Extended. So they would be good on a lifted truck.
I bought them for a project and that project changed plans, and now I need some different shorter shocks.
Looks like they go for $360 / pair new on Amazon. I'll sell them for $300 shipped, continental US.

Bilstein 7100s are the race shocks that Bilstein sells. One of the nicest and offering. About four steps above the 5100.
In between are the 5150, 5165, 6100, and then the 7100
They're nitrogen charged and fully customer rebuild-able, so you'll never have to buy another shock, just rebuild kits.
Self-adjusting deflective disc valving
High-flow piston reduces harshness
Independent rebound & compression tuning
True high pressure gas shock, no emulsion
They're Digressive valving, 255/70.
Which means 255 rebound, 70 compression.
I had some Bilsteins on my previous truck, a Tacoma, with 170/60. They were perfect for that light truck when unloaded. The F150 needed the next step higher, and that's 255/70.
There's an explanation of what those valving numbers mean here, if you are interested.
As you can see from the length information I posted above, they are longer than the 5100 series, which supports greater lift.
19.53 in vs 17.68 Collapsed, so 1.85 in longer than the 5100
31.1 in vs 28.9 Extended, so 2.2 in longer than the 5100
The 5100 already supports a 1" longer rear lift. Therefore these would support a 3" higher rear lift. Which is enough for a 4" lift kit
They use Heim joints also, which are more precise than bushings. The new F150lifts.com BOSS suspension is using Heim joints, for an example.
For my F150 forum member, for a few bucks extra I can throw in the grease cups I was going to use with these (they cost me $30). They are rubber cups that surround the heim. Load them up with grease and you won't have to worry about them wearing out.
They're not marketed directly to the F150 crowd because they have 1/2" mounting bolts. Our trucks are 12mm, so you'd have to buy different bolts, and drill out your stock mounts slightly (1/2" is 12.7mm).
Here's a link to the Bilstein catalog, where I got my specs.
Probably too much information, right?
