Action Clutch Stage 2 Clutch Kits
Action Clutch single disc clutch kits contain a range of street to high performance clutch systems built using American materials which are all locally sourced as it has been done for 60 years. Action Clutch staged kits come complete with the clutch disc, pressure plate, throwout/release bearing, pilot bearing/bushing (when applicable), and alignment tool. Action Clutch Stage 2 clutch kits for street and occasional track use offer a 110 percent increased holding capacity. They utilize reinforced steel-backed full face Kevlar® friction material and feature a single diaphragm heavy-duty pressure plate, while maintaining an OEM-like pedal feel, super smooth engagement, and heat dissipation. These kits are engineered for vehicles that have basic bolt-on cars or NA vehicles with headwork, such as cams, very low boost or nitrous setup. These fibers have a low static to dynamic friction coefficient, making them an ideal choice for applications where smooth engagement is essential (e.g. daily driving, stop-and-go, off-road driving). Due to the properties of Kevlar®, the stage 2 kits have an exceptional lifespan with minimal increase in pedal feel and a more confidence inspiring engagement. Select the kit designed for your vehicle. Pressure plate and clutch disc features: * All clutch covers feature ductile iron friction plate * Reinforced heavy-duty drive straps * 4-stage, heat-treated diaphragm spring * 100 percent dynamically spin balanced * American grade rivets * Full enclosed spring retainers * Sprung hub for easy engagement

Exedy OE Flywheels
Exedy offers OE flywheels for a variety of applications, including many Honda©, Acura©, Subaru, Scion models from early 2000s and up. Flywheel hot spots can cause chatter—and resurfacing a flywheel doesn't always remove hot spots. The flywheel may appear fine, but the hot spots will often still be there. These stock replacements are machined from ductile iron in different sizes and configurations. They smooth the power output in reciprocating engines, store and deliver energy at higher rates than the source, and control the orientation of a mechanical system using gyroscope and reaction wheel. It's often recommended to replace both the flywheel and clutch at the same time. Order the flywheel designed for your vehicle.

Dorman CV Joint Boots
Dorman CV joint boots protect your CV joints from destructive dirt and moisture. A common cause of CV joint failure is cracks in the CV boot. When the boot is cracked, it allows dirt and grit to mix in with the grease and wear down the parts of the joint. CV boots should be replaced as soon as cracking is visible in their rubber folds. Pick up one of these Dorman CV joint boots to eliminate the problem.

XClutch Stage 1 Clutch Kits
XClutch Stage 1 clutch kits offer a variety of performance upgrades for both street and track applications. They are designed in-house and normally utilize a single plate organic, ceramic, or carbon friction disc along with an upgraded factory-style pressure plate. XClutch kits utilize a similar mechanism to the factory clutch, making them ideal enhancements for most vehicles with low to mid-level performance modifications. Stage 1 clutch kits are available in three distinct performance clutch packages—sprung, rigid solid, and steel-backed organic. Features and benefits of each: * 1A sprung organic—this range has been specifically designed for street vehicles that have minor engine and general performance modifications. These kits offer a sprung organic friction disc that allows for great drivability, while offering improved clamping force through the use of a performance pressure plate. * 1G rigid solid organic—with a rigid center version of the organic disc, this range is ideal for street vehicles and light track use. These kits are often available with a lightweight alloy pressure plate and performance flywheel. * 1T steel-backed organic--this range offers a higher burst strength by bonding the organic friction material directly to a steel backing plate. These kits are ideal for high performance vehicles used on the street with occasional track use.

ACT Race Clutch Discs
ACT race clutch discs are available in three distinct styles--choose the options that best suit your application. Spring-centered discs are the most popular and feature reduced driveline shock and spline wear with quieter operation. Rigid-hub versions offer improved durability but increase gear noise and spline wear. For either of those hub designs, you can choose six pads for better heat management and engagement, or four pads for the quickest shifting. Sintered iron discs offer the highest torque capacity and ultra-high heat capacity. They're designed for cars using clutch-less shifting or drag racing transmissions. Additional product details: * Premium ceramic friction materials provide high-heat tolerance, high coefficient of friction, and low wear rates * Carefully broached splines provide exact fit onto the transmission input shaft for long spline life and better clutch release * Heavy-duty torsional dampening springs are provided in the best sizes and spring rates to help reduce noise * Drive plates are made of high-carbon steel; heat-treated and black zinc coated to resist bending, cracking, fatigue, and rusting * Certified to SFI specifications
