Red Line Synthetic Limited-Slip Differential Break In Additive 4 oz
If your Corvette’s posi is chattering louder than a couple of guys arguing about which generation is the best, this Redline Friction Modifier is the stuff that shuts it up fast. Think of it like smoothing out the attitude in your differential. You just add an ounce at a time to your clutch-type limited slip and it takes the harsh, grabby feel right out of it. It works with synthetic or regular gear oil and drops break-in temps by up to 50 degrees F, which is a big deal when you’re trying to keep that rear end alive. Redline’s ester-based formula is built for serious gear protection, better efficiency, and less wear, so your Corvette runs cooler, quieter, and happier. Basically, it’s like giving your diff a deep breath and a cold drink after a hard pull.
