Engineered with a high viscosity-index formula compatible with synthetic and petroleum gear oils, it delivers consistent performance across temperature variations. Trusted since 1979, this product is a go-to solution for professionals seeking reliable, long-lasting drivetrain smoothness.

## Description

Red Line differential friction modifier and break-in additives can be added to any gear oil to replace the limited-slip additives. They are ideal to tune a limited-slip unit.

Review: Worked a treat! - I fitted a limited slip differential gearbox to my mini which creaked and moaned and groaned when turning slowly. Added half a bottle of this to the oil in the gearbox and the problem was gone instantly.
Review: Brillant stuff will buy again - Bought this as I have a Drexler plated diff and I’ve purchased various top brand gearbox oils but still had slight noise and chatter going round very tight corners. So I put in normal 75w 85 oil in and added a ounce at a time until noise and chatter had gone, I can say it has no noise what so ever and this is a brilliant product.

## Features

- ENGINEERED - to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
- DIRECTION - Add 1oz at a time to clutch-type limited slip or posi-traction units to eliminate chatter
- HIGH VISCOSITY-INDEX - to provide relatively constant viscosity and film thickness with varying temperature change, exceed API GL-5 specifications
- COMPATIBLE WITH - both petroleum and synthetic gear oils
- WHY RED LINE - Established in 1979, Red Line Products perform & protect better than any on the market. No compromises

## Questions & Answers

**Q: Would the 95 Isuzu 4x4 front differential benefit from this additive? I know the rear limited slip diff does!**
A: No, unless it's a limited slip after market and specifies such. On the rear positive,  too much would cause slippage between the plates.  Just ad enough to stop the clanging.  Too much would lesson the Limited slip .

**Q: Can this be used in redlline dct fluid that is used in a manual tranmission with lsd?**
A: It was purchased for my son.  I didn't use it.  My son is a car mechanic, so I think it is a good product.

**Q: Would this help a 95 Isuzu front 4x4 differential? ...that chatters around corners on pavement?**
A: Check your u-joints but if there ok. Let me know if it worked. Differential Gear oil is supposed to be replaced on a regular Preventative maintenance Schedule. I don’t know what the mileage is on your car is but it couldn’t hurt “unless your vehicle is not a LSD Diff.” Thanks!

**Q: do I need that for my 99 chevy express 1500 V8  with amsoil 80W90 together?**
A: My chevy Silverado 2500HD ran better after adding a 4oz. can of Redline with the rear gear oil. There is also an additive for the transfer case GM put in during a service. I would double check before putting that in the transfer case. Keep on reading, you'll find the answer. Good Luck
