Take your Haldex AWD system to the next level with RacingDiffs’ Block Disc Set, engineered to fully lock power distribution for 100% traction. This upgrade is ideal for drag racing, drifting, and rally applications, ensuring all-wheel drive is permanently engaged for maximum grip.
• Zero Traction Loss on Launch – The stock Haldex system operates as an on-demand AWD, meaning it only engages the rear wheels when the front wheels start slipping. This delay in power transfer can cause traction loss at launch, leading to inconsistent 60-foot times and slower ETs. With RacingDiffs Block Discs installed, the AWD system remains fully engaged at all times, ensuring instant torque distribution to all four wheels the moment you hit the throttle.
• Dyno-Tested Power Handling – The Haldex system is designed to transfer up to 300hp to the rear wheels, which we confirmed in our 4x4 dyno tests. If your vehicle is pushing more than 300hp to the wheels, the extra power will not be evenly distributed—instead, it will result in front-wheel spin, as the Haldex clutch pack reaches its limit and starts slipping. This can cause inconsistent launches and excessive tire wear on the front wheels. By locking the Haldex unit, our Block Discs ensure that power is evenly distributed to all four wheels, giving you maximum grip off the line.
• Perfect for High-Power AWD Builds – If you’re running a big turbo setup or pushing high horsepower, the last thing you want is torque lag caused by an inconsistent AWD system. With a fully locked Haldex, your drivetrain delivers all available power efficiently, ensuring hard, predictable launches and better power transfer through every gear shift. Whether you're running launch control or transbrake setups, the locked Haldex system allows for better weight transfer, less drivetrain shock, and improved stability throughout the run.
• Stronger & More Reliable – No risk of cracks or failures, backed by a Lifetime Warranty
• Reversible – Easily switch back to normal Haldex operation anytime
• Maintenance-Free – No special oil or servicing required
• Versatile for Multi-Use Vehicles – Swap between street and race setups effortlessly
