Bilstein 6112

The overall length of the coil over doesn’t change, so the lift is gained on higher notches by preloading the spring. I don’t see how that CANT affect ride quality.

 

Not sure what you’re saying.

The clip notch just changes the relative position of the spring along the shock axis. The piston in the shock moves within the valve with this adjustment. But since these aren’t position sensitive dampers (like 8112s) the damping profile is the same. The coil spring length isn’t compressed more or less.

 

good read if you haven’t seen it.

Ok, please explain how this works. If we take two unassembled 6100 coil over setups and install the spring on one to the 1st knotch and the spring on the other to the 6th knotch. Both springs have to be compressed to assemble. The 6th knotch spring has to be compressed an additional 1.5” and it remains compressed when it is sitting on the perch.

Both assembled coil overs are the same length. The lift is coming from the additional “stiffness” of the more heavily compressed spring resisting further compression from the weight of the truck. The entire spring isnt moving along the axis of the shock as the top mounts are both fixed in place. Another way to get the same effect is a longer spring that is compressed more to fit into the coil over or a stiffer spring that doesn’t sag as much under the weight of the truck.

How am I wrong here?

 

Just added 6112s (5100s rear) at what I believe is the top notch. My opinion is that it’s way too high up front and I’m concerned with the UCA angle. This is on the road and it looks like the UCA is pegged as far as it will go with little room for down travel. Sitting on 285/70/17.

Is this angle ok? Do I need to drop to 4th notch and add new UCAs or am I overthinking this? Will This improve angles and still clear w/out CMC / major trimming?

Appreciate the help!

 

If you just installed them, they will settle "a little" over the next couple of weeks, but it does have a very high UCA and CV angle right now. At the very least, if you are going to stay that high, I would put some JBA UCA's on there.

 

Thx! JBA preferred over SPC?

 

It is 6 of one and 1/2 dozen of another. SPC is great for people that want more alignment specs in other ways. I know that the ball joint for their specific UCA, you can only get through them. The reason why I went with JBA, is that is allows for more Caster (I was able to get mine to 3.5) and they come with a lifetime warranty. I also like the fact that they have zerk fttings on the bushings and the ball joint itself, the ball joint is very heavy duty and can be replaced very easily, and the angle of articulation of the ball joint is fantastic. With SPC, you also need to have an alignment guy who knows how to set a SPC ball joint because of the multiple positions of the ball joint itself. Personally, I would not go with anything else but JBA, but that is just my opinion.

Thx crash. Sold on JBA.
I’m not a color geek and could do without the red but ok.
Picking up the standard hi caster.

thx again!

 

I got 3.8 caster with SPC UCA’s for what it’s worth.

 

Looks like you have a spacer installed? Did you get that kit from ready lift?

 

Looking to get some feedback on this before I pull the trigger. Looking to buy the 6112/5160 set to 5/6 notch, Deaver AAL, Dirt King UCAs, do a CMC to fit 285/70/17 Toyo M/Ts and switch out the bushing while the lift is installed.

Is there anything else y'all feel is necessary to make this set-up run the best and prevent future issues?

 

Looking good! Some people say go full leaf pack replacement since AAL will eventually sag quickly. Just what I’ve heard and something to look into. Especially with a 3 year old truck.

 

I have a 3 leaf add a leaf from headstrong which sagged a bit after 2 years. Should have done a full leaf pack to begin with. Buy once cry once.

 

That’s crazy to me. I don’t get why that happens. 1 leaf just can’t fight the others for very long is all I can guess.

 

I had my 6112s/5160s installed alittle over a month ago and after driving with them around town and doing a little wheeling this past weekend I can say I really like them. I wish there was alittle rake, but it ended up level which I am fine with, it looks like it has alittle bro lean in the pics due to the angle I was parked, but in a flat parking lot it is level. I went with SCP UCAs, set the fronts at 5/6 and went with an Icon AAL with the overload left in. The went with the setup because I have a camper shell (200-250lbs), RCI sliders (~125lbs), and full aluminum skids (~70lbs). I noticed when I was camping and had the back loaded up that I was sagged out and figured with all the weight that leaving the overload in would make sense.

I prefer the ride over stock because it is firmer in a way I prefer; way less brake dive, less boaty feel when turning, and less bouncy. It still soaks up bumps well and feels more composed over a rough road or a washboard road. I did the Oriflamme Canyon trail this past weekend for those in SoCal and I could feel a difference for sure.

Tires are 265/75/16

 

I am considering going with a very similar setup, what add a leaf did you end up going with? I am trying to go with a 5/6 cip setting while making the truck sit as level as possible. I have a 16 double cab OR with a auto and I dont have any additional weight on the truck.

 

I'm having a hard time determining the spring rate to choose between 650# and 700#, as well as the notch settings with the following setup:
CBI T3 Full Hoop Bumper w/ winch (steel) ~200lbs
RCI Front IFS & Transmission Skids (steel) ~82lbs
Mobtown Rock Sliders (steel) ~140lbs

I am looking to get 2" of lift up front with the added weight vs. stock suspension no added weight.

I also have a custom built pop up camper for the back ~450-500lbs, and carry a good amount of gear.
Rears I plan to run 5160s and Deaver Expedition III pack w/ Timbren bump stops.

Wondering also if I should really consider the aluminum T3 bumper to save on weight..

What are others running with heavy loads up front on the 6112s, seems like lots of variations on what to do.
