• Molybdenum-Ceramic Coating: Friction surfaces are coated with a motorsport-grade Molybdenum-Ceramic layer, vastly superior to OEM bare metal plates.
• No Metal Shavings: Unlike factory metal-to-metal contact, the coated plates prevent galling and metal debris formation inside the differential.
• Direct Replacement: Designed as a plug-and-play upgrade for Dana/Spicer Power-Lok LSD units — no machining or modifications required.

• Higher friction coefficient for more aggressive and consistent diff lock.
• Improved traction and grip in off-road, racing, and spirited street driving.
• Greatly reduced wear and warping under extreme heat and load.
• Enhanced heat resistance for stable performance over long runs.
• Longer service life compared to stock plates, with less maintenance required.
