Slide Tube Penske

The Slide Tube Penske by SWIFT SPRINGS is a precision stack guide engineered for shock absorber assembly and tuning in high-performance suspension systems. This component is essential for racers, suspension technicians, and performance enthusiasts who demand consistent damping characteristics and repeatability across multiple shock configurations. The stack guide controls spring preload and load path geometry, making it a critical element in fine-tuning vehicle dynamics for competitive and street applications alike.

Constructed from durable black plastic, the Slide Tube Penske features a 2.074-inch inner diameter and 2.245-inch outer diameter, with a 6.75-inch height specification that accommodates standard Penske shock tube architecture. The cylindrical design ensures smooth, consistent stacking of shims and springs without binding or misalignment, while the precision-engineered dimensions maintain tight tolerances critical for shock valving performance. At 0.41 pounds, this lightweight guide minimizes unsprung weight while delivering the rigidity required to maintain load integrity under dynamic suspension articulation.

The Slide Tube Penske is ideal for racers building custom Penske shock configurations, suspension shops assembling performance dampers, and competitors seeking to optimize shock responsiveness through precise shim stack geometry. Installation is straightforward—simply insert the guide into the shock tube bore before adding shim stacks and springs. Compatibility is confirmed with standard Penske shock platforms. This is a single-unit component, so verify your complete shock assembly requirements before ordering to ensure you have all necessary stack guide elements for your application.
