Need some Help on torsion adjustment...ASAP

[TheRhino]

Finished the install on the Slee medium lift with diff drop.
OME: 860's on the rear, 303001 torsions, 60002's on the rear and 60000 on the front.
Need to make final adjustments on the torsions and read all the threads on dimesions from bottom of rim etc., but still confused.
Got the front off the ground and the current measurement is 32-1/2" from bottom of 16" rim to fender. What is the correct dimension?

There is no "correct" dimension. OME suggests leaving 20mm of droop in the suspension, beyond that it's up to you. I'd suggest leaving the recommended travel in there, I had mine near maxed out and the suspension would bottom out over speed bumps and such, made great noises.

Thanks.....making that adjustment right now. Nice day in Houston to work in the garage

20mm of droop measuring from where? at wheel/tire? or at bumpstop?

Sorry Cory, should have quoted the original comment. I am wondering where you measure the 20mm of droop? at wheel/tire? or at bumpstop?

Someone correct me if I'm wrong, but this is the way I would measure droop. With the car settled at it's normal ride height, measure the gap between the top of the front wheel and the bottom of the front fender. Then use a jack to lift the front end just until the wheels start to lift off the ground. Measure the gap once again, it should be at least 20mm delta between the two numbers.

The center of the hub to the fender lip will give you a more acurate reading. By using the center of the hub it doesnt matter what size rims or tires if you are comparing measurements. Body lifts are a different story.

Thanks I will measure to see where it is. Mine was set by the installer 5 years ago and I have never known if it was high or low. Does anyone know what others recommend besides the 20mm that OME put out there?

Lookin good, what size tires are you running?

23 1/4" (center hub to fender) is what both of my 100 series measure at with the shocks disconnected. I run at 21" and top out the suspension very little.

SLEE's recommendations

Just got off the phone with SLEE and they recommend a minimum of 2" when the weight of the vehicle is on the tires vs no weight on the tires (wheels off the ground).

 

[Anthony.L]

2 inches = 50mm

OME recommends 60mm of droop. Closer to about 2 3/8".

Step by Step procedure?

OME recommends 60mm of droop. Closer to about 2 3/8".

Has anyone posted a step-by-step procedure on the proper way to adjust the torsions?
I know it seems simple, but obviously it's not since this topic continues to get mixed opinions.

Yeah, I was sitting here looking at a ruler and thinking 20mm seemed a little small.

Jack up truck
Turn anchor bolt to either lift or lower truck
Remove jack and measure, stop when you want
Repeat for other side

The mixed opinion is how high you want to go, how much droop you want to leave, etc. and that's all subjective.

So, when wheel is off ground and I am adjusting the tbar to lift the truck, should I see the wheel go up or down? I was thinking it should go down. but I am not sure.

thanks!

You will more then likely not see the tire more at all. What you are actually adjusting is the spring preload on the torsion bar. You are not moving the placement of the suspension or wheel.
