Max-Gear is an ultra-tough automotive gear oil. It's designed to maximize power and provide unsurpassed protection to heavily loaded gears. It makes gears run smoother, quieter, cooler and longer without overhauls. Max-Gear outperforms other gear oils because it combines the highest quality synthetic oils with Royal Purple's proprietary Synerlec additive technology. Max-Gear is recommended for use in truck, motor home/RV and automotive front or rear differentials, manual transmissions, and lower gear units of marine engines that specify use of an API GL-5 or GL-4 fluid. All viscosities of Max-Gear are formulated with hypoid friction modifiers necessary for use in clutch or cone type differentials. No additional additives are necessary.

Review: I recommend if you have always stayed up on maintenance like I have. - Great product, I also use their motor oil for regular everyday driving. No racing at all and it had worked great for me. I just tried this gear oil and ai can already feel the difference. No complains this car. I just put it in last night and drove it today 06/27/25 and it feels good.
Review: Best gear lube on the market - Basically the only gear lube I ever use. Great for transfer cases and sub trans applications. Quiet down them gears and provides excellent lubrication to keep them from wearing. You can't go wrong with this product. This is not a motor oil or a transmission oil. This is for differentials and transfer cases also known as a sub trans on some utv's.

## Questions & Answers

**Q: Always use luca 80w-90 in ford ranger 2.3l, 7.5" rear diff.  wanted to try this.  any issues with it being a 75w vs 80w?  is this better than lucas?**
A: I use the royal purple 75w-90 in my RAM 2500 differential. My differential is made by American Axle Manufacturing and I talked with one of their mechanical engineers who said the viscosity requirement is determined by several criteria with ambient and operating temperature being big determinants. I live in a warm climate so he said I could use a heavier weight oil. With that knowledge I don't believe there is a big enough difference between the 75 and 80 other the better lubricity at lower ambient and operating temperature. He did recommend amsoil but said the royal purple is just as good.

**Q: I have graphite/ composite  synchronizers in my  transmission , will they be damaged by the use of  anything other than the "Castrol syntorque" recom**
A: I've had the best experience with Redline MT90 in manual transmissions. RP was not working well with syncros (grinding gears when shifting).

**Q: I know that the product description says that it is not for use in wet clutch systems, but will it be okay for use in motorcycle final gear (shaft)**
A: Will be fine as a motorcycle final gear oil. I use this product in two BMW motorcycles, a BMW R1150RT and a R1200S, as a final drive oil and also as the transmission oil.

**Q: Will it work in a bmw x-3 transfer case, the manufacturer calls for their fluid # TF0870?**
A: No. Use the BMW fluid.

Basically the only gear lube I ever use. Great for transfer cases and sub trans applications. Quiet down them gears and provides excellent lubrication to keep them from wearing. You can't go wrong with this product. This is not a motor oil or a transmission oil. This is for differentials and transfer cases also known as a sub trans on some utv's.

### ⭐⭐⭐⭐⭐ Great fluid
*by M***S on December 6, 2024*

Purchased for the front and rear diff in my Durango SRT. I had a "clunking/jerking" feeling if you would accelerate hard and after reading many reviews, the diff fluid needed to be changed. I was at 50k miles and was supposed to be done at 40 so I figured this would fix it. It sure did. It has the additive in it already and I will say putting this fluid in my Durango made it happy. It was a way better price then the Mopar brand of fluid and works just as well. I did purchase a pump to get the fluid into my rear diff. The front was easy to fill. Royal Purple has always been a great brand and still doesn't disappoint.
