Advice for Bilstein 5100 front shocks please!

Yes you need an alignment. Mine felt great even on the highway, guess what.

 

Mine @ .85", with just factory leafs:


@ 1.75", with 2" AAL:

 

x2. anytime you change the ride height, the suspension geometry will be different, and you will need an alignment. At best, your tires would wear prematurely.

 

I have billy's--------and a few other bits. Do yourself a favor and buy coilovers. Just do it. I could on and on as to 'why', but I got shit to do and its 80 degrees outside.
I wish someone had given me this sage advice when I stumbled into the saloon. Wait----they did, and I ignored them. Good luck, brother.

 

So I need an alignment to correct the toe and camber?

 

They're actually stock springs pulled from a 2015 with 1k miles. They're set at .85 believe it or not

 

You have two options:

Stock coils on 5100s set at .85

Or

OME 883 coils on 5100s set at 0

 

Zach, you sure your perches aren't flipped?

That looks like a good amount of lift for .85, on stock springs. The fact that you have a 1" block to level it, tells me something doesn't sound right.

 

Well my leaf packs are shot, so I needed the block to bump the rear up. How do I check the perches? The off-road shop installed the fronts.

 

These are upside down:



These are installed correctly:


When installed upside down, the ride height will be ~2" higher than it should be. It's pretty sketchy, since the c-clip is not kept in place by the spring perch, when installed like this.

When installed correctly, the spring perch surrounds (envelops) the c-clip, not allowing any movement.

 

Alright, I'll check them out in a few minutes to see. I'll post pics too

 

.85 and 1/4 spacer on the passenger side, 1/2 on the driver side. Will be balls perfect. And look tits!

 

Not sure what adjustments need to be made on yours, could be closer to spec than mine was. But like fitz235 said, anytime you change the front geometry it's necessary. I'd hate to think the $900 I spent on tires last week were wearing out early or unevenly.

 

Quick question: if you put on a new wheel/tire package that has a different offset/backpacking, do you need an alignment ??

 

You should be getting an alignment done whenever you get new tires.

 

Mine are set at .85 everything else is stock. About 500-600lb in the back in this pic.

 

I would. That's why I just paid for a lifetime alignment. My truck is 5 months old, brand new tires, a single alignment is roughly $80. $180 for unlimited alignments for the life of the vehicle seems like a steal to me.

 

Wow did your dealership offer that lifetime alignment for $180??

 

No, Sears auto, upgraded my stock tires. Firestone does the same, not sure on price. NTB has it for 5 years I think. I 've spent way too many hours looking at tire prices lately.

 

This is good feedback. This might be a dumb question, but does it make a difference if the truck is 4x4 compared to 2wd? I ask as far as the weight of the truck perhaps making a difference. I was partially leaning towards the 1.75, but from doing more research and with the feedback of this thread seems .85 might be the way to go.
