The critical component to ensure the safety, comfort and performance of any vehicle is the suspension. The confidence and pleasure owners derive from their J2X® MkIII rests upon the complicity between the drivetrain and the suspension. But, since driving styles and skills differ from one person to the next, we have integrated fully adjustable suspensions, precise steering and efficient braking to tailor the J2X® MkIII to maximize your driving pleasure.

Independent Front Suspension (IFS)

Includes cast stainless steel spindle assembly & A-arms with E-Z Eccentric™ alignment, billet calipers, billet coil over shocks, rotor cover, ball joint caps and extra heavy gauge steel cross member. The IFS includes rack and pinion rear mount steering, sway bar and large vented 4-caliper disc brake

Independent Rear Suspension (IRS)

Heavy torque loads are transferred to a 9” Ford limited-slip differential. The hardened half-shafts are equipped with 12” 4-piston drilled and slotted rotors for impressive braking power. Inboard brakes reduce unsprung weight allowing the springs and shock absorbers to be more effective in controlling the suspension’s movement. The MkIII’s parking brake locks the differential for a very secure immobilization of the vehicle.


QA1’s shocks and struts are optimized to enhance performance by providing a soft, comfortable ride at the low end of operation or a firm, high performance ride at the high end of operation. Changing the valving on adjustable shocks and struts is as simple as turning the knob on the base of the shock, giving you the versatility to go from the street to the track without ever removing the shock or strut from the vehicle.

Adjustability Options

4-Way Adjustable

  • Truly independent compression and rebound adjustment at high and low shock speeds
  • 18 positions of high speed rebound on one knob and 18 positions of low speed rebound on the other knob on the shock body; 18 positions of high speed compression on one knob and 18 positions of low speed compression on the other knob on the shock reservoir
  • Fine tune for low shock speed situations, such as corner entry and exit, and high shock speed situations, such as hitting bumps or curve
