I'm pleased with the replacement tongue jack for my Lippert leveling system. Our travel trailer weighs 10K lbs., and our truck weighs 8500 lbs., and the jack was getting weak when asked to lift that kind of weight to help "set" the tension on our equalizing trunnion bars. The new one is noticeably quieter, as well. The free shipping was nice, and delivery was on time!

Hey neighbor! I'm glad the new jack was a major upgrade for your set up!

After 1 year of service, we are well pleased with the Lippert replacement tongue jack for our 2020 Rockwood 8328. To its credit, the original Lippert jack gave us plenty of warning that it was getting tired of handling the load of raising the combined 18,500-lb. weight of our trailer and truck to tension our equalizing trunnion bars, without leaving us to handle the job by muscle power. The replacement jack is NOT cheap, but it is built specifically to coordinate with and be controlled by our computerized, factory-installed Lippert Ground Control self-leveling system. We havent regretted spending the money to replace the original jack before it entirely quit. Our rig asks a lot from our tongue jack, and the Lippert replacement jack is handling the job with no complaints so far.

by: William 05/31/2026

Happy with jack, disappointed with it not coming with manual crank handle like most replacement Lippert jacks.

etrailer was the only place I could find this particular tongue jack and they had it for a fair price. It took a couple weeks before they were able to ship it, but it arrived in a few days once it was on its way. My only complaint is that the jack was not packed well. The box should have been reinforced at the foot end of the jack and I would have wrapped the head with some padding. The foot end broke out of the box and then the jack bounced around in the box for the rest of the journey. Fortunately there was no major damage done.

This tongue jack is still doing its job after a busy year of use.

by: Ward 06/05/2023

I have a lippert ground control TT leveling system on my travel trailer and the electric tongue jack stopped functioning. This replacement part was the exact part that I needed to get back up and running again. It was simple and easy to install. 3- bolts to remove the jack, 1- "red" power wire to disconnect and 2- quick disconnect wire fittings to separate and the jack came right off. Attaching the new replacement jack was just as easy as removing the old one.

Exactly what was needed after trailer slipped off the block and bent the shaft. Easy replacement.
Was miss quoted on delivery time took 2 weeks to get the jack but works like the old one even a bit quieter than damaged one. I would still use etrailer again for future parts.

Product installed and works great. It was a return item, because it has thread lock on the inside of the controls. Doesn't bother me, but maybe double check.
It took 15 minutes to install. Great plug and play.

A year later no issues at all. We use our toyhauler often with lots of remote camping. It’s worth to spend the money to get quality.

by: John 03/21/2026

Easy install. Took 10 minutes. But, sold the RV.

by: Ivan 08/26/2020

The power jack works great. A little slow but when you Re hooking on or off you should not be in a hurry, thats tje reason why I had to buy a new one. Anyways it works great with my lipperr auto leveling system, the jack was the exact replacement.

The tongue jack to replaced by Lippert to work with the Lippert leveling system. It worked very well but the package was damaged but luckily the jack was not affected. If not for the package, I would give it 4 to 5 stars rating.

by: James 03/06/2020

Ordered electric jack. Received the first one and it was damaged. I called the company they sent out a new one that day and also sent me a return shipping label to return the damaged one. I received the replacement very quickly and already installed it and it works great. I am very happy with the service and products from etrailer and would recommend them to anyone.

by: Danny 04/10/2023

It had a broken light switch when it arrived. They were great to send me a replacement switch for it. Everything is working like it should now. Great customer service second to none! Thanks e trailer

Had a trailer jack that did not work from new. Contacted etrailer, they said they would put another one on the truck that day and I should have it by Tuesday. It arrived the next day. Great service! Great service after the sale. Always go there first

Smooth Sailing,

Works as expected. Easy installation. Raises slowly, so patience is needed when you're arriving at your campsite and want to get set up.

Replacement Electric Tongue Jack For A 2021 Jayco Eagle 312 BHOK Travel Trailer
Hey John, The Lippert Smart Jack Electric Trailer Jack w/ Footplate # LC643589 is only going to have a power wire to connect to your battery.

Troubleshooting the Manual Switches for the Ground Control TT Tongue Jack
Hey Michael, thanks for reaching out. I'm sorry to hear the buttons are not working. I completely understand the frustration you may be experiencing. Since the jack # LC421366 is tied into the Ground Control system, you’ll want to check what voltage you are getting at the main control board for the tongue jack. When you do this, make sure you are completely disconnected from all charging sources. I also reached out to Lippert to see if they had any further suggestions, and they asked...

Can I Drill New Mounting Holes to Install the Replacement Tongue Jack for Lippert Ground Control TT?
Hey Keith. If you're talking about drilling into your trailer's tongue then the answer is yes.

Hey Steve, I don't know exactly what jack your 2020 Flagstaff 832 KBS Classic has on it currently we can still help as powered a-frame jacks basically are all interchangeable.
