ScienceofSpeed top mounts are lightweight, CNC-machined aluminum, with a hard anodized finish that replaces the factory steel top mount for shock absorbers using aftermarket straight springs (not compatible with conical factory springs, or factory-style lowering springs). High-performance urethane bushings replace the rubber factory top mount bushings. The top mount and bushings were engineered to support the entire weight of each corner.
The ScienceofSpeed Shock Absorber Top Mount Kit is designed for three applications:
Shock shaft:
The top mounts are available for shock absorbers that use 10mm or 12mm shafts.
Springs:
Compatible with 60mm or larger springs. Not compatible with 2.25" or factory springs. For applications using factory or factory-style tapered springs, use the factory top mount with this kit. Spring isolators are available for 62mm or 65mm springs. Spring isolators are only used for applications that use springs that mate to the bottom of the top mount (example 1). For applications that use 60mm springs mounted to the bottom of the top mount, spring sheets are available from Swift Springs (part no. 044101). For applications using iLIFT, Stance, or other compatible suspension lift system actuators, any spring size may be used that is compatible with the actuator. Contact the suspension lift manufacturer for recommended springs.
Known compatible shock absorbers:
New design eliminates the need to use the glued-on KW spring bushing for bottom mount spring applications.
This kit includes one pair of top mounts. Two pairs are required for front and rear installations.
