The RCV Jeep JL CV for Dana 44 is 18% larger than our previous Dana 44 design and uses our same Dana 60 architecture. Tests prove our axles to be twice as strong as OEM. Even with big tires and big power there are no worries. RCV Performance Ultimate CV Axles are low maintenance and operate with a smoothness you can feel - whether off-road or on the street. All backed with a Lifetime Warranty against breakage up to a 43" tire.
RCV axles are a direct OEM replacement for Jeep JL Wrangler Rubicon and Jeep JT Gladiator Rubicon. CVJ44-JL eliminates the Jeep's "Front Axle Disconnect" coupler for a 1-pc shaft, but keeps full functionality of the FAD module. No warning lights, and no further modifications needed.
Kit fits all JL and JT Rubicon models with 2.0, 3.6, 6.4 (392), and diesel engine options.
Additional Information
- RCV Dana 44s are stronger than OEM Dana 60 u-joint axles
- We launched this new 18% larger CV specifically for the Jeep JL & JT Rubicon
- Running RCVs gains more strength than a Dana 60 while allowing you to keep the same wheels, less weight, and more ground clearance
- Axles outboards are gun-drilled with a grease fitting at the end for easy maintenance when needed. No need to remove any parts (but a center cap on the wheel)
- We offer two versions - the FAD 2-pc version and a FAD eliminator 1-pc version. Both versions retain the FAD module. No warning lights, no issues.
- Coupler utilizes upgraded aircraft grade materials
- RCV FAD kits use a new bronze bushing, replacing the OEM plastic.
- JL Rubicon Dana 44 axles backed by a limited Lifetime Warranty against breakage up to a 43" tire.
Axle set includes right and left CV axle shafts, outer stubs, SST seals and installation tool, installation instructions, synthetic moly grease, and installation hardware. Black oxide coating is standard. Optional nickel plating is available for extra corrosion resistance in salty environments - contact us for details

STA-BIL Start Your Engines! Because Sometimes Engines Need a Pep Talk
Size: 2 fl oz
So, STA-BIL Start Your Engines! is basically that friend who shows up uninvited but actually saves the day. You know, the one who doesn’t ask questions and just gets your engine running when it’s feeling moody or sluggish.
Does it work? Of course it does. Like, “put a little in your gas tank, say a quick prayer, and voila!” kind of work. Suddenly your car remembers how to start, and you feel like a mechanic genius without actually lifting a wrench.
It’s simple, it’s reliable, and it doesn’t judge you for letting your gas sit around until it gets that “I don’t want to cooperate” attitude.
Pros:
Makes your engine start like it just had an espresso shot.
Easy to use — even if you’re barely awake in the morning.
No weird smells or smoke signals, just clean, smooth starting.
Cons:
Won’t fix your “I forgot to put gas in” problem.
Sadly, can’t make your car drive itself to work (yet).
You might start relying on it a little too much — hey, no judgment.
Final Verdict:
⭐️⭐️⭐️⭐️⭐️ – 5 stars.
If your engine is feeling lazy, this stuff just works. It’s like a pep talk in a bottle for your car. Highly recommended for anyone who’s ever cursed their ignition.

Cleans Out Working Carburetors
Size: 2 fl oz
I recommend this product for engines that will in fact start but not run well. I highly recommend it for that specific purpose, which it is designed for. It cleans the inner workings of the carburetor. Of course, you will have a cleaner carburetor if you take it apart and clean it with proper tools and a proper carburetor cleaner.
You spray it in the gas tank, start the engine, and let it run a bit. It will not start an engine with a totally plugged up carburetor. Nothing is going to do that. Nor is it a fuel stabilizer, as one previous reviewer seemed to think. Nor is it a product to be used to bring life back to stale gasoline, as another reviewer seemed to think. The only thing to do with stale gasoline is drain it out and pitch it. Nor is it a product to be used for cleaning a carburetor you have taken apart to clean. You should use a proper carburetor cleaner for that purpose.
I've given it four stars because it cleans out mildly plugged up carbs. It is not a miracle solution for really neglected carbs as the name suggests.
