Bilstein 5100 Max Setting - Driveshaft Angles

tuckersnator · June 19, 2018

Hey all, I didn't really think about this when installed but had a friend ask me if I did anything about the new driveshaft angle for the 4X4 and main shaft. I installed the 5100's on max setting and added a 1" raise in the the back. The Motofab blocks had a taper to maintain the angle, (I think) but now I am worried about it being correct and if I need to do a transfer case drop? Do you think that it is lifted enough to worry about? I cant really tell by looking.

Are you experiencing any strange vibrations?

I'm not but didn't want to prematurely wear out anything without noticing symptoms.

No. You’re Not even breaking 2” of lift on max setting up front.

Hooksets are free...

If your drive line angles are out of tolerance you'll probably feel a high frequency vibration... More of a buzz than a shake. If you wanna be extra sure just for piece of mind, grab a magnetic angle guage from a parts store and check the angles. A Google search and a bit of reading will tell you all you wanna know about what the angles should be. But with only 1" change in the rear, and no new vibration, I'd say you're fine.

You lifted the front and youre worried about the rear driveshaft angle?

Yeah I am hoping the rear is fine because its only 1" and the blocks were tapered. Its the front 4x4 I am mostly worried about since the front is up 1.85".

Yes, the transfer case shaft to the front differential.

I could be wrong since I'm not sure what method was used to raise the front, but for less than 2" of lift, your diff probably didn't move. The lift is probably all in the struts. Your cv axles will be a t a slight angle between the diff and the wheel, but I doubt your diff was relocated for such a small amount of lift.
