The 7500 series small bore “SB” shock was developed for use in the left rear of a late model. Through testing, we have found some advantages in certain conditions that when the shock produces enough load at a certain position, it eliminates the need for a coil spring. By utilizing just the nitrogen area in the shock to produce your spring load, it allows for more compliancy, due to the air spring characteristic, over bumpy surfaces. This shock is also effected by heat, so if your extended LR load value is 100lbs at 80°F, when the shock is at operating temperature, say 110°F, your load value may now be 175lbs. This helps raise the rear deck when on track at temp.
This shock comes with spring hardware. Some sanctioning bodies dictate you must have a spring at every corner, the spring hardware allows you to run a “dummy” spring.
