California Residents: Proposition 65 Warning


Our RCV Dana 44 CV Front Axle Set are the Strongest Dana 44 Axles!!!


We know RCV products are the best. They do in house and third party testing to ensure that these products perform at the highest level.
The 4340 alloy steel is a heat treatable and low alloy steel containing chromium, nickel and molybdenum. It has high toughness and strength in the heat treated condition.


On average, RCV CV axles are almost 2X as strong as the OEM axles!!


You might be wondering if you have to re-grease these RCV Performance cv joints. Yes, but only a couple times a year because they are packed with grease! Unlike, u-joints that you have to grease almost every time you go out!
The low maintenance aspect is what I like best about the RCV axles. I have run the best of the conventional u-joint style axles but they have all been high maintenance. Jim Creel


RCV product quality cannot be matched! RCV products are made with only the highest grade materials, they only buy U.S. steel. Better materials and workmanship comes with a higher price. You get what you pay for. When our customers open the box we want them to know that they got what they paid for.
Are cv joints more expensive than u joints? The RCV Ultimate CV Joints are actually less expensive than the highest end U-joints. Even though RCV CV-Joints are almost twice as strong as the best U-joint setup out there!


We encourage use of RCV products in daily drivers. They have done extenesive testing to make sure the CV axles can stand up to cross country road trips as well as hitting the trail hard. Try this with traditional highend U-joint setups, you will wear your joints out in no time!


If you have a warranty issue, call us. The warranty states, "You break it, we replace it!"

Specific 78-79 Bronco info

One thing that's different (aside from the obvious) about the RCV axles is the 30 spline outer axle. The 30 spline design adds approximately 30% more contact surface between the outer axle and hub making for a much stronger outer. This necessitates a locking hub change or you can opt for drive flanges (slugs).

Due to the larger diameter of the CV joint, you must use the large opening knuckles like the 76-79 Ford disc brake knuckles. You will want to factor this in when doing a complete axle build.

These are extremely tough axles, I'm running 37's in a full size bronco and got tired of breaking u joints, these were the answer. My only complaint is the sort of lack of installation info for my specific application - 73-79 1/2 ton Dana 44, I had to remove and install a couple times due to the fact that these don't use the original inner wheel bearing seals except for one..

Challenges with RCV axles

Ordered for dana 44 78/79 Bronco axle. Spent hours trying to figure out what spring clips would not compress to allow bearing assy to push on inner axle. Discovered rubber "O" ring was under spring clip. Removed "o" ring and assembly went right on. Called RCV yesterday and they stated that some axles had the "o" ring because of problems with bearing wondering on some lockers and axle wondering in rear. But they have since changed design to thicker spring clip. Can only figure my axle had both the "o" ring and the thicker spring clip. May save you customers some time by removing these "o" rings.

Great customer service
