When your suspension hardware wears out, the ride can get rough and noisy. This replacement wet shoulder bolt brings back the smooth travel of your Equa-Flex tandem axle suspension. It’s built with a 9/16" diameter shoulder and a usable length of 2-5/16", giving the perfect fit for your setup so the suspension moves freely again without slop or binding.
Road grime and moisture can quickly damage unprotected hardware. This bolt is constructed of zinc-plated steel to stand up to rust and corrosion. That extra protection means the bolt stays solid through miles of rain, dust, and salt, keeping the suspension connection strong over time.
Keeping suspension parts greased helps reduce wear on bushings and keeps things quiet. The integrated grease zerk in this wet bolt lets you apply lubricant right where it’s needed without disassembly. Regular greasing keeps the movement smooth and prevents the squeaks that come from dry joints.
A tight, precise fit keeps everything locked in where it belongs. The 7/16"-20 fine thread and 13/16" hex head give reliable torque and easy maintenance. With an overall length of 3-1/4" including the grease zerk and 2-7/8" under the hex head, the dimensions are dialed in for a solid, proper connection every time.

Today we're going to take a look at the replacement wet shoulder bolt for Equa-Flex Tandem Axle Suspension. Now this is going to be a direct replacement from Liberty Components for that bolt on your Equa-Flex Tandem Axle Suspension kit. This is going to work for part numbers LC279687, LC279688, and LC314336.As far as our dimensions, going from the end of the threads to the top of the bolt it's going to be 3 1/4". Going from the end of the threads to the grease Zerk, it's going to be closer to 3 5/8". Our diameter is going to be 9/16. And basically, this is just going to be that direct replacement.
We'll have our grease Zerk on the one end, and then the hole that our grease will come out to make sure that everything's lubricated, and we don't have any squeaks or issues; keeps our bolt lasting for a long time.And that's going to do it for our look at the replacement wet shoulder bolt for Equa-Flex Tandem Axle Suspension.

I sold the fifth wheel a year ago
Well made and fit perfectly. A little more $$ than others but made to fit by Lippert.
Perfect fit! But, why aren’t the nuts included too?

I checked and I do not offer this type of bolt that includes the lock nut. You can buy the lock nut separately as part # 1137306.
Showed up with the package all ripped open with parts missing

Wet bolt was a replacement for a Lippert factory wet bolt that broke. The new wet bolt is still in place and has given me no problems.
Great fit & finish. Remember to order the flange nut with the bolt. They are separate.
Worked Great, direct replacement on my RV suspension
You guys were great. The program walked me through to insure that the parts would fit my trailer. The video of how to select the proper type and how to mount them were top notch. Thank you so much. You will always be the folks I go to for parts!
Doesnt come with nut and these are one time use, so spend a half a day looking for nut or lock tight your old one in not a great idea for suspenions, wrong zerk doesnt fit theads half way in, for $XX bucks you think it should be gold plated

Hello, the wet bolt does not come with a nut. There is a link to the nut that goes with this bolt linked on the product page as a related part. Also you can find the dimensions for the the wet bolt listed on the page as well as a schematic showing the lengths.
Yhis was suggested as a replacement for a product that was out of stock. Saved money and shipped immediately. Thanks.
Really expected new lock nuts to also be included. However product arrived as descibed.
The support staff at etrailer is GREAT. The USPS not so much.
I installed them this spring, here are a few pictures. I also installed all new bushings and greasable pins. It was a good thing I replaced these as the center bushing on my old equalizers were broken. The new equilizers are a couple inches taller than the old one, raise my trailer over an inch. This worked well as my new truck is higher than my old one.
Info for this part was:

I am sorry to hear that the bolt length did not work for you. The useable part of the bolt we list as 2.31 inches long and the overall length is 2.87 inches long. What length of bolt do you need?
