Has anyone put bilstein 5100 adjustable 0-2.5” struts on their tremor? Seems like a better option than a puck style level kit.

Does the spring hit the UCA? Or do you need to run aftermarket UCA’’s?

There is a video on YouTube where they installed the 5100’s but they changed the spring also and I can’t find any information on the replacement spring. I assume it’s narrower to it doesn’t hit the UCA.

Thanks!

I have 6112s + 5160s on my tremor. I did something called a Split Lift; I have the spring set at the +2” position (+1” on a tremor), then I have a 1” puck. 1” in-strut and 1” out-of-strut is the best for spring wear and also keeps the shock in its optimal position. In total I have a ~2” level.

I wouldn’t recommend maxing out the spring position (2.5” position), your spring rate will be slow and your ride will suck, especially with an already highly digressive shock.

The spring does have a smaller diameter, I have the one that comes with the Bilstein kit and i don’t have any UCA collisions at full droop. I’ve measured about 9” of front wheel travel with my setup. Works great.

What did you get for the 1” puck? I’d like to get some of my down travel back.
 
Get the eibach stage 2r kit.

Any idea what your overall height is? I keep debating an upgrade but I gotta be careful with height clearance (boo)

Enough to drive it through and park it under an 84” garage door with a 34” tire

@PNWTremor what kind of puck did you use? Split Level is a great idea if there is no bind in the UBJ or collision between UCA/Spring or LSM/CV Boot. Any idea what the mounting length of your 6112 was?

No bind or UCA collisions. I only have a 2” level, some dudes on here have 3”.

I don’t know what the mounting length is

How do you like the 6112 and 5160 set up? I purchased these and haven’t had the chance to install them yet. I have them set at the 1” lift as well. Overall better than stock ride?
 
What I heard from Bilstein is that the lift for a Tremor using the 5100 will net the same lift as advertised for each clip position.

I have not installed the lift yet so I can not confirm.

Is there anyone with the 5100 in the front that can confirm the lift at their clip position?

So that's exactly what I did as well with the Eibach 2R setup. The "2 inch lift" on the eibach, really only gets you +1 inch on the Tremor. The "2 inch lift" is as compared to a stock F150.

Ok so +1 net from Eibach set out of the box to their top recommended value.

I didn't like the set. It was still at 39.5F and 42R.

Then I added a solid "1 inch level spacer" which is a 0.5 inch thick piece of metal. It did raise the nose 1 inch at the wheel well.

So now I gained 1 inch from the eibachs, and 1 inch from the puck. For a +2 net gain in the front to sit finally
40.5F / 42R

The control arms are far away from the eibachs, the ball joint is not at a super unnatural binding angle, and the ride is very very close to OEM and not harsh.

I can recommend this setup, and I am VERY picky about ride quality.

Nice. The spit-lift route is the way to go right now until there is some more affordable and / or tremor specific shock options. My setup ROCKS it. Being able to re-use the factory UCA is also nice, saves me money.

I think the cut-off for how much we can level out trucks is about 2" anyways before you start having issues with CVs.

Glad the Stage 2R kit is working for you.

Yeah imo the 2 inches I gained looks "right" also. You'd have a LOT of wheel well to fill if you went higher. 33s would look too small for sure if you went higher. If you really really cared, dropping the bed 1 inch is an option, but I like the overall high stance. It's like an F150 with a 3.5 inch lift basically.

It’s interesting how this was different on your truck than mine. I just re-checked my measurements and the Eibachs out of the box added 2” on the dot, at least to the nearest quarter inch. Though as I type that I think I may be able to have a guess, which is mine had like 55K miles before changing and yours was pretty much new, right? Maybe my factory setup had settled some. I went from 38” to 40” on both front sides.

52k miles when replaced OEM to Eibach. After Eibach at out of box / highest set it was 39.5F and 42R.
 
So what did you guys use for the 1" tophat spacer? Seems like none of the companies make them (other than some small guys on ebay). half inch puck leaves enough threads to slide it on the existing studs?

I have 1/2” spacers on my 6112s. I think they are .35”, I didn’t measure them. Same issue for me though couldn’t find 1” spacers. Seems like they are too big for the studs to make it through but too small to have the attached stud design.

1/2 inch pucks lifts the truck 1 inch measured at the wheel well. Yes there is a couple threads remaining past the nut after install. It's safe.

Well here is what I measured with what I have:
2.3” Auto Spring Spacer has a 1.67” puck
2.0” Auto Spring Spacer is 1.49”
0.5” Spacer is 0.4”
I didn’t measure the installed lift those are manufacturer numbers
