• Under equal traction conditions, both wheels spin the same speed. While turning, the wheels are allowed to spin whatever speed they need to without binding.
• As one wheel loses traction, the gears inside the LSD engage progressively, sending more and more torque to the wheel with more traction. This limits torque sent to a low traction wheel while increasing that sent to the high-traction wheel, resulting in drastically less wheel spin.
• If a wheel gets near to a zero-traction situation (wheel spin is about to occur), the LSD becomes fully locked, stopping the low traction wheel from spinning faster than the high traction wheel.

The following PNs are for non-Sport diff axles. If you are converting from a Sport diff to the JXB/WaveTrac rear LSD, you’ll need to purchase a pair of these or equivalent. We recommend just grabbing a used set on eBay. They’re generally pretty cheap. Both left and right are the same.

Your car’s trans and diff codes are found on the build label. It’s located in the trunk and on the warranty voucher page in the warranty and maintenance manual.

If you’re under the car, you can also find the code of your regular diff engraved on the bottom.

If you can get to the top of the diff, it’s also printed as the 4th-6th characters on the bar code sticker (if it’s still attached).

On the Sport Diff, the code is engraved on the bottom side near the front.
