650# vs 600# coils on 6112s

Here's some dope on my lift.
Since installing my 6112s and Deaver Stage 3 springs I have also replaced my body mount bushings with Energy Suspension Body Mounts and a 1" body lift.
Think the new body mounts added 1/8" to the front.
I also discovered my new Deavers are side specific and my installer put them on the wrong sides.
So... Don't know how much this is going to help you.

Measurements day after installing 6112s and Deavers
FD 23 1/8" (20 " stock)
FP 23" (20 1/4")
RD 24 7/8" (22 1/8")
RP 25" (22 3/4")
2 3/4" to 3 1/8" in the front and 2 1/4" to 2 3/4" in the rear.

Now after new body mounts and body lift
FD 23 3/8" (20 " stock) = 3 3/8 - 1" body lift = 2 3/8"
FP 24 1/8" (20 1/4") = 3 7/8 - 1" body lift = 2 7/8"
RD 25" (22 1/8") = 2 7/8 - 1" body lift = 1 7/8"
RP 26 1/8" (22 3/4") = 3 3/8 - 1" body lift = 2 3/8"

2 3/8" and 2 7/8" in the front and 1 7/8" and 2 3/8" in the rear.

Hoping the rear will match side to side better after I swap sides with the deavers and might even help the front side to side as well.

FYI. Got my springs from Accutune, they have an exchange program.
My springs are by Eibach

 

Don't think you need to get an aftermarket uca to run the 6112s.

 

Will I damage anything if I got #650 with no added weight? I plan on a steel bumper but not at the moment.

 

My thoughts exactly but what if you keep it at the top setting would it damage anything or have a rough ride?

 

Think you should get advice from a fellow 3rd gen.
I don't think you'll damage anything.
FYI, usually you get the 600# springs included with the 6112s and pay extra for 650#s.
So you could ask for the 600# and change if needed.
I did that and also got them through accutune cause they have a spring exchange program.
I do like my setup.
Got on a scale last week 5860lbs
Full tank and loaded up for 4 days.

 

FWIW switched to 650lb Coils for sliders and full skids. Gained lift back from weight with 600. 650 coils without weight will be stiff IMO. Ride quality is very subjective but that’s my 2cents. Very stoked on set up now

 

Yeah thats what I hear if no added weight no need for 650. Just would hate to have to buy new coils when I get a steel bumper. What setting do you have the 6112 at

 

Exactly bro. I’m at 6/5 setting 650 coils I’m at 2” of lift. If I plan on a bumper most likely I’ll go 6/6 with 1/4” spacer driver side. I’m also on 32’s

 

So you running the 650 but no weight? I always heard 650 would push that extra .5
I always wonder if I set it 6/5 with a 1/4 spacer on both sides I can push the 2.5

 

I’m running 650 with sliders and full skids. Yes 650 add 1/2” of lift to compensate for weight.

 

650# with 1.5” lift on otherwise stock truck for 20k miles. No Taco lean and felt great on and off road. Just added an an aluminum bumper and 8k winch (85 lbs) with no sag but a bit of lost compliance over small, high-frequency bumps.

 

Right on thanks for feed back

 

Any plans to move it up to 5/6

 

I’m running ADS, so it’s about turning the collars. I do have more preload on the driver side.

 

Anyone got #650 springs for sale? My #600 feel too soft with body armor hi line bumper and winch

 

Just made the switch to 650. I feel
Your pain. Just bite the bullet and buy some 650 won’t disappoint

 

Thanks for the info

 

I know "subjective bla bla" but what do you define as too soft? wouldn't you want a softer ride for rough trails? I guess if you were to compare it to stock OR susp. is it softer than that? I plan on 600# with some skids and sliders and no bumpers

 

Too soft for me is, you'll bottom out too easily. Small ditch or bump.. yup, you are hitting the bump stops hard. Oh and the nose dive when you brake is terrible.

You'll be fine with 600s for armor and sliders. As soon as you throw in a front bumper and winch, you'll want 650s or even 700s depending on the bumper.

 

You will be fine with 600lb coils.
