Series 300 Clutch Kit
Clutchplace offers high-performance industry-exclusive upgrades for import and domestic applications. Designed for automotive enthusiasts who want increased durability and performance at a reasonable price, each clutch kit comes in a platform to match the performance enhancement made to the vehicle.
Because some vehicles are used in situations where O.E. specs just don’t measure up, we’ve engineered heavy-duty and high-performance Series Upgrade (SR) New Clutch Kits that feature a unique combination of application-specific torque capacity, coefficient of friction, and clamp load characteristics.
Each SR Upgrade relies on time-tested proven technology to provide longer life and optimum performance, while also taking into account the fact that each component must work in conjunction with the other driveline components. It’s a delicate balancing act. If clamp load and torque capacity ratings are increased too much, component failure will likely occur in other areas such as the mechanical or hydraulic linkage. If these ratings are increased too little, the components will simply fail when subjected to the added operating demands.
SR300 Kits are also designed for applications in which an extreme improvement in clutch capacity is required. Miba sintered metallic friction material is utilized in order to provide the highest coefficient of friction, although mating surface wear is increased and drivability is more abrupt. As a result, SR300 Kits are not recommended for drivers with limited manual transmission experience.
*Note for car:
- Applications:
- Engineered for applications with engine upgrades from 100-150 horsepower.
- Heavy-duty pressure plate upgraded with increased clamp load.
- Heavy-duty disc lined exclusively with Miba sintered metallic friction material.
- Clutch capacity increased by a minimum of 100 horsepower.
- Engineered as good street/strip choice.
- Drivability is more abrupt due to higher co-efficient of friction of the friction material, but this application can still be street driven.
- Engineered to be compatible with the OEM hydraulic/cable clutch release system.
*Note for truck:
- Applications:
- Engineered for trucks with engine upgrades from 100-200 horsepower.
- Ideal for extreme towing or hauling extreme loads.
- OEM pressure plate, or a heavy-duty pressure plate upgraded with increased clamp load (depending on the application)
- Heavy-duty disc lined exclusively with Miba sintered metallic friction material
- Engine torque capacity increased by a minimum of 200 ft. lbs.
- Spike torque capacity, idle noise control, and drivability are identical to SR100 kits.
- Drivability is more abrupt due to higher co-efficient of friction.
