RideTech StreetGrip Coil Springs
RideTech StreetGrip coil springs deliver ride quality and crisp handling. These dual-rate springs will allow your vehicle to move smoothly and effectively over small road irregularities via compliant spring rates. When your vehicle compresses the springs far enough, through large bumps or cornering, the transition to the firmer spring rates will control the bump or body roll. Even though RideTech StreetGrip springs work best as a complete system, the coil springs are compatible with other OEM components and will offer incremental performance improvements. Order the pair designed for your application.

Silver Sport Transmission Crossmembers
Silver Sport transmission crossmembers are CAD-designed from heavy-duty formed and powdercoated steel. They offer strength and accuracy, two essentials of a crossmember. These SST vehicle-specific crossmembers are stiff and resistant to deflection, meeting or surpassing the original design, meaning they won't flex during hard launches or on rough roads. They are engineered to provide the proper driveline angle eliminating installation issues seen with adjustable crossmembers, as well as vibration issues and possible U-joint damage. Exhaust and ground clearance are also taken into consideration. Silver Sport transmission crossmembers locate the transmission at not only the proper height and angle, but makes sure it stays there, regardless of power, torque, or road conditions. Order the one for your specific vehicle.
