A. NEW! Stage 3 Coilover Suspension Kits
“The Mopar Stage 2 and 3 equipped PT Cruiser and PT Turbo have exhibited the most dramatic change of any of the vehicle platforms. With the addition of this system, the vehicle balance, roll stiffness, and front to rear transition have been exponentially improved, while actually adding additional driving comfort! One drive and you are hooked. . . . And the look is just right. This is exactly what the designers had intended. A must have. Incredible!”- Mopar/KW Engineering Team
The Stage 3 Coilover Kit includes all the features of the Stage 2 Kit. In addition, the Stage 3 Kit allows drivers to adjust the damper setting of the suspension system for the ultimate in personalization.

The Stage 3 Kit is height adjustable and rebound adjustable from 20% under to 50% over Stage 2 settings. Rebound adjustment takes place via an adjustment screw at the end of the piston rod, and primarily affects the low and midrange rebound dampening.
