Three new features of spec.2 are: ・ The ball bush is used for the shock bracket to create smooth and accurate shock attachments. ・ Increased air room capacity by changing the top cap. Eliminates the stiffness when the shock is in full compression. ・ A standard application of φ0.7x3 piston, making firm and flexible set ups possible. The kit comes with 4 shocks and a key chain wrench for ride heights adjustments.
