Hi all,

Wondering if anyone knows factually or from experience. I'm looking at putting Bilstein 5100's on the rear of my truck, but I *may* want to put 3" lift blocks (for 1.5" of lift above stock FX4) in the rear. Are the 5100's long enough to accept another inch and a half of down travel?

Thanks,

Z

They're long enough if you buy the ones made for the extra lift height .

I just put 5100's on my '13 and the rears were plenty long to have accommodated another 1.5"
That being said, I wouldn't put a 3" level on the truck. It's too hard on the front end. The CV's and ball joints die prematurely. 2" is all I'd go with a level. If you want more, get a 4" lift.

PerryB He would only be putting a 1.5” lift in the rear. Removing stock block and adding the taller block in the rear.

1.5” to 2” front lift is highest I would recommend in front using new coilovers. If you do that your front and rear will be lifted the same and you keep the rake.

i would add the leaf if I was you original poster. Also helps relieve squatting under load. Blocks won’t do that.

Pretty sure a 3" block with Bilsteins has been done many many times. For those who still want a little rake.

The front will be Bilsteins set to 2.1"

I believe the 5100's are rated for up to +1". The stock blocks in my FX4 were 1.25" and I replaced them with 2.5" for a lift of 1.25". If the 5100's aren't happy, I can't tell. All seems OK.

ZeroTX

Sounds good. I was thinking of maybe a 2.5" block to be safe. If the shocks are working fine and not over extending, then all is good.

Ok, installed the front Bilsteins at 2.1 setting and the truck still a good 3/4 inch of rake on the back, so my thoughts are don't bother with a rear block. I appreciate all the feedback

Looks great!
