ACT Releases Mod-Twin Clutch Kits for 2024-2026 Ford Mustang GT

Advanced Clutch Technology (ACT) has released a full range of SFI-approved 10.5-inch Mod-Twin Style Clutch Kits for the 2024-2026 Ford Mustang GT. Designed for increased torque capacity, durability, and drivability, the new clutch systems are engineered for both street and racing applications.

The ACT Mod-Twin system features a 10.5-inch twin-disc design paired with the company’s Mono-Drive modular hub system. A forged aluminum cover and Chromoly XACT Streetlite flywheel help reduce rotating mass, with the complete kit weighing 49 pounds compared to the OEM 60-pound clutch and flywheel assembly.

ACT says the clutch kits are designed to support a wide range of power adders, including superchargers, turbocharger systems, and nitrous applications. Depending on the selected configuration, the Mod-Twin can support up to 1,496 lb-ft of torque while maintaining drivability and serviceability.

The Street versions of the Mod-Twin clutch are designed for everyday use, offering light pedal effort and quiet operation while supporting up to 1,169 lb-ft of torque. ACT’s HD, XT, and XX Race variants are built for drag racing, road racing, and rally applications where higher torque capacity and durability are required.

The modular design allows users to configure the clutch system using multiple clamp load options, alternate friction plates, and either sprung or rigid Mono-Drive hubs. ACT also notes that the Mono-Drive hub system increases spline life and overall durability compared to conventional twin-disc clutch designs.

Each kit includes the Chromoly XACT Streetlite flywheel, clutch hardware, and alignment tool for installation using the factory-style mounting configuration.

Eaton to Showcase GM and Jeep ELocker and Detroit Trutrac Differentials at SEMA 2024

2024-10-29T20:19:42+00:00

Eaton’s Mobility Group is rolling out two new aftermarket differentials for diesel-powered GM trucks and Jeep off-road builds, designed to deliver serious traction upgrades. The new Detroit Truetrac 31-spline differential fits GM’s 11.5-inch rear axle on 2020+ 2500HD Silverado and Sierra models, bringing extra stability and grip for heavy-duty towing or demanding terrain. For Jeep fans, the 35-spline ELocker offers enhanced durability and torque control, a perfect match for 2018 and older Jeep models with Dana 44 axles, including Wrangler JK, TJ, LJ, and CJ variants.

These new differentials will debut at SEMA 2024, giving enthusiasts a first look at Eaton’s latest innovations. The Detroit Truetrac delivers smooth, automatic, limited-slip functionality using helical gears, staying out of the way during normal driving but seamlessly locking up when the traction challenge ramps up. For those looking for on-the-fly control, the ELocker shifts from open to fully locked with a dash switch, ensuring drivers get instant grip for tough climbs and technical obstacles.

Backed by years of refining their differential portfolio, Eaton’s new additions showcase the brand’s commitment to performance-driven upgrades for popular North American vehicles. Both units will be available from Eaton’s U.S. distribution centers starting late Q1 2025, ready to elevate traction and durability for work and adventure alike.

GrimmSpeed Pitch Stop Mount

2024-06-21T16:50:36+00:00

When manufacturers design OEM chassis mounts, the primary focus often lies on minimizing noise, vibrations, and harshness (NVH), as well as keeping costs low. For those seeking to boost their vehicle's performance, this presents a significant opportunity. GrimmSpeed’s latest offering, the Pitch Stop Mount, is engineered to enhance the driving experience by providing a firmer, more connected feel to your drivetrain. This improvement translates to more predictable shifting and increased confidence during spirited driving.

At the heart of this upgrade are 75A durometer polyurethane bushings. These bushings ensure that the transmission remains stable under high torque conditions without introducing excessive drivetrain noise and vibration to the chassis. Designed to fit seamlessly with almost all AWD Subaru manual transmission setups, this part retains the OEM fitment. A minor difference exists between the 5-speed and 6-speed models, but it's easily addressed with the included 5-Speed Adapter Spacer, which fits between the stainless steel bracket and the transmission cross member.

FITMENTS:
2004-21 Subaru STI (6MT)
2002-14 Subaru WRX (5MT)*
2015-24 Subaru WRX (6MT)*
