Performance Haldex clutch pack upgrade kit available for Generation 1–3 and Generation 4–5 AWD systems. Designed to restore stronger torque transfer to the rear axle, improve traction and provide more consistent grip under demanding driving conditions.
This upgrade is suitable for Haldex-equipped Volkswagen, Audi, SEAT, Škoda, Volvo, Ford, Land Rover and other AWD vehicles, depending on the selected Haldex generation.
Besides superior durability, the RacingDiffs clutch set provides significantly higher grip and more reliable torque transfer. It is highly recommended for performance road cars, track-day vehicles, drag-racing builds and high-power AWD applications.
Factory Haldex clutch plates are frequently unavailable as separate replacement parts. The RacingDiffs Haldex clutch set allows the original coupling to be properly rebuilt instead of replacing the complete unit or relying on a used assembly with unknown wear.

Which variant should I select?
Select the clutch set matching the Haldex generation installed in your vehicle: Generation 1–3 or Generation 4–5. The two clutch sets are not interchangeable.
Will this fit my car?
Fitment depends on the Haldex generation rather than the vehicle model alone. Model years can overlap, so check the identification details on your Haldex unit. If you are unsure, send us your VIN and photographs or identification details from the coupling.
What problem does this upgrade solve?
It helps restore AWD torque transfer and traction when the original clutch pack is worn. It also provides more consistent engagement during demanding performance use.
Is it better than the original clutch pack?
The RacingDiffs set is designed to provide stronger, more consistent grip and improved durability under repeated heat cycles and high drivetrain loads.
Why rebuild instead of buying a used Haldex unit?
Used Haldex assemblies frequently have unknown mileage, clutch wear and maintenance history. Rebuilding your original coupling with new clutch plates provides a more predictable and reliable solution.
Can I install it myself?
Correct assembly, clutch-pack clearance and Haldex servicing are essential for proper operation. Professional installation by an experienced transmission or AWD specialist is recommended.
