Hi everybody. Andy here with etrailer.com. Let's take a real quick look at these replacement bevel gears for your HappiJac Truck Camper Jack Systems. Now this is going to replace the bevel gears for one jack in your HappiJac truck camper jack system, and on your screen I am including all of the model numbers that these bevel gears are going to fit. As you can see, this is going to work with the current series of jacks and also at the bottom of that graphic there, those discontinued series of jacks as well. So if you have one of those jacks, one of those model numbers, these bevel gears are going to be exactly what you need.
These gears are directly from HappiJac, so you can trust that they're going to fit right in place of those original ones that you're needing to replace. You're not gonna have to worry about fit, compatibility issues or anything like that. Well, that's gonna wrap up our real quick look today. I do hope that it was helpful for you. Again, my name is Andy.
Thank you for joining me.
Excellent service from ETrailer guys!
You are my go-to source for all my parts & supplies.
WOW! I was worried about getting the parts as I was told that they were discontinued. Your employees got to work, found what I needed, and here the parts sit. You have won me over as a customer. I was surprosed that ALL of my emails about the part were answered. That in itself is unusual. Keep up the good work!

Hey Timothy. I'm glad that we had exactly what you were needing and answer all your questions! Do you have any plans yet of where you are going to head to with your truck camper this year?
Worked out perfectly.
Fast and friendly service! This was the part we needed to fix a malfunctioning HappiJack truck camper jack. I requested next day delivery and we were able to get on with our vacation!!
The part for perfect and was delivered earlier than expected.
Exactly what I needed and delivered as expected thank you
These gears are just what we needed to replace the stripped ones in our Happijac 4150 jack. The customer service at etrailer was excellent. Before I ordered them I asked if they would fit and not only did I get a reply, but instructions for installation. Great service!
Etrailer always has the hard to find parts I need and ships the right parts, well packaged in a timely fashion. Plus their website is well organized making parts easy to find. They are my first choice for RV and trailer parts.
Service was great. Got the hard to find parts I needed quickly. Would use etrailer again, when I need RV repair materials.
Well made, heavy duty and a perfect fit. I thought I needed to replace the leg entirely ($500 plus), but, it was just a broken bevel. A little tricky to replace, but, not impossible.
Gears are a perfect match to old ones. Expensive but hard to find. No free shipping to Alaska, not even a partial break, but few outlets will even ship to Alaska. Shipping was
very prompt and efficient.
Nice gears. I got the gear that sits vertically to work on a Shelby 2,500lb drop jack. The gear that sits horizontally will not work on the Shelby, but the vertical one works. Shelby is out of business, so good to know if you want to fix a broken Shelby.
Great product, exactly as described, fair price and quick shipping. Great customer service experience.
Gears work excellent. I actually used these to rebuild a HappiJac bunk bed system that is gear driven. Works like a champ.
Second time I’ve replaced the bevel gears in one of my 4150 Happi Jacs. They both are now like new.
Quick service and quality parts. Thank you
Got the right part that was shipped and received on time.
I like American made products. Easy ordering and fast delivery.
