Leaf Spring U-Bolt Torque Safe-T-Plus

I am in the middle of correcting a major screw-up with my Safe-T-Plus steering stabilizer courtesy of Camping World. The folks at Safe-T-Plus have been extremely helpful so after the sale customer support is A-1.

I have submitted this question to Safe-T-Plus, but wanted to get some input here if anyone has run across this same issue. The torque value for mounting the anchor plate to the leaf spring U-bolt is 200 lb-ft per the Safe-T-Plus installation instructions. The torque value for these same U-bolts, which require periodic checking per the chassis guide, is 140 lb-ft.

Curious if others have noticed this and how you installed the steering stabilizer? I would be willing to bet that Camping World used an impact torque wrench and the actual final value is unknown

"Time is money" the old saying goes. Looks like they got your money and took less time doing it.
We had a saying in our shop for the truckers- 3 ways to do a job, quick, good and cheap.
But you only get 2.
If it's quick and cheap, then no good.
Quick and good, the not cheap.
Good and cheap, then not quick.
Happy Glamping.

I could be wrong, but I really don't think that torque values on chassis bolts are that critical. I have installed quite a bit of chassis components over the years and never had a problem. I have also never found a loose leaf U-bolt/nut. I recently installed my SafeTSteer and just snugged them with the impact then tightened with a wrench.

Seems to me like both torque numbers could be correct. The U-Bolt torque is 140 and takes into consideration bolt stretch. 200ftlbs on the u-bolts could fatigue the part of the ubolt that curves around the axle. 200ftlbs on the nut to hold the plate in place seems correct too. That part of the ubolt should be able to handle the extra load. The extra clamping force of 200ftlbs will secure the plate in place better.

If you have already confirmed the 200ftlbs number with safe t steer I would go with that.

Leaf Spring U-Bolt Torque Safe-T-Plus

Safe-T-Plus just responded to use the chassis torque value of 140 lb-ft. Confusing, yes? One logical explanation is the 200 lb-ft may correspond to the maximum torque value for that thread and material but I havenít verified this yet. Canít see why the extra bolt preload would be required to hold the anchor plate in place. I would really like to speak with the designers.

Next trip to the coach I plan to tighten all to 140 lb-ft and await some other input from Ultra RV Products who are also investigating this.

Could you tell us what Camping World did to mess up the install?

I went with the chassis specs when I installed my track bar. My opinion only, if you torque the fastener more than specs, you WILL weaken the fastener. Break or strip the threads. It was about all I could do 140 lbs any ways. Fasteners have a torque spec for a reason, bolt stretch, and clamping pressure. More is NOT better. I did retorque mine after 500 miles, had no change since the install.

Wrong anchor plate, installed on wrong side and bolts installed upside down from instructions.

Wow. Terrible workmanship from CW.

Glad you got things figured out and the correct torque specs. That will give you piece of mind.

Leaf Spring U-Bolt Torque Safe-T-Plus

The correct people at Safe-T-Plus have been notified and I was assured that instructions would be updated and replaced in existing kits on the shelf

So they are going to revise to 140 lb-ft?

So has anyone had a catastrophic failure at 200 ft lbs?
