South Bend Clutch Stage 2 Daily Driver Clutch Kits

South Bend Clutch Stage 2 Daily Driver clutch kits are engineered for vehicles with high performance modifications. The heavy-duty pressure plate has an increased clamp load with little or no increase in pedal pressure to offer stock feel, while increasing strength and durability. The organic disc material has a high metal content that increases the co-efficient of friction by two times over a stock lining. This greatly increases rotational strength up to a 12,000 rpm burst point for high performance. South Bend Clutch Stage 2 Daily Driver clutch kits are recommended for daily performance, street, and moderate race vehicles. Select the kit designed for your application needs.

MSS Automotive Fully Adjustable Sports Suspension Kits

Suspension components are key to making sure your car is riding smoothly on or off the road. With upgraded suspension components like these fully adjustable Sports suspension kits from MSS Automotive, you can unlock the full potential of your vehicle's performance. Triple Engineered Technology adjustable spring kits put the driver in full control of their ride and handling experience. MSS Automotive utilizes two active springs with three separate spring rates: the single-rated orange spring and the dual-rated black spring. This combination delivers a huge range of capability in operation—a smooth and almost linear transition. The relatively low initial spring rate absorbs small bumps in the road, thereby increasing grip. It then transitions to a secondary spring rate which enhances vehicle handling during cornering, giving you the ultimate control of your driving experience. Thanks to its patented triple stack spring technology, MSS Automotive can for the first time deliver improved performance, comfort, and safety, within one product—and without compromise. Choose the suspension kit designed for your application.

MagnaFlow Universal Catalytic Converters

MagnaFlow universal catalytic converters by Car Sound form the basic building blocks for many applications. The main benefit of universal catalytic converters is that one unit may cover a wide variety of vehicle makes and models. Installing universal converters often requires the use of welding, cutting, and tube-bending equipment that is readily available to most professional installers. They are extremely well made, with features such as: * A ribbed body that minimizes expansion and distortion when the converter heats up. They form a channel that protects the cushioning mat from direct exposure to exhaust gasses, and hold the ceramic catalyst in proper alignment. * A 1/2 in. lap joint where the necks meet the body. The neck does not extend into the converter body, where it could hamper exhaust flow. * Manufactured with separate dies on different sized inlets. Putting larger neck sizes on smaller bodies would reduce the flow of the converter and the quality of the product. * A monolithic honeycomb catalyst. The ceramic is designed for maximum flow and surface area. The coating method is strictly controlled to maintain exact specifications. * Seam-welded close to the converter body for a strong, tight bond. Welding along the edge could allow the converter to expand like the folds in an accordion, allowing the catalyst to move around. * Heavier-gauge stainless steel, tip-to-tip. They do not use inferior mixed weights and materials. * An aluminized or stainless OEM-style ribbed heat shield that creates a rigid wall of protection against heat and adds to the structural stability of the converter.
