Tuned Performance and Reliable Damping with the King Shocks 2.5 PR Coilover Shock and Piggyback Reservoir

Engineered for demanding off-road use, the King Shocks 2.5 PR Coilover Shock integrates a 2.5-inch body diameter with a piggyback reservoir to deliver 8 inches of consistent travel, superior heat management, and rapid on-ground ride height adjustments for lifted chassis configurations.

• Integrated Piggyback Reservoir: Mounts the nitrogen-charged reservoir directly onto the spring perch to isolate pressurized gas from shock oil, eliminating cavitation under heavy loads while expanding fluid capacity to dissipate heat faster during sustained rock crawling, desert running, or track events.
• Coilover Spring Integration: Eliminates the guesswork of sourcing separate springs and adapters by providing pre-machined threads for direct coil spring installation, allowing drivers to quickly tweak ride height, manage squat, or change spring rates without removing the shock from the vehicle.
• Adjustable Valve Circuitry: Comes equipped with adjustable internal bump stroke plugs (IBP) and selectable damping circuits that let users customize the high-speed compression and rebound response to match varying payload weights, tire sizes, and terrain impact forces without needing external tools.
• Swivel End Cap Alignment: Features pivoting shock eyes designed to absorb minor bracket misalignments and bushing movement, ensuring bolts seat properly during installation and reducing binding stress on control arms that can lead to premature component failure.
• Rugged 2.5-Inch Construction: Utilizes a larger-diameter main piston tube compared to standard stock units to support higher hydraulic flow, paired with durable dust sealing systems that repel mud and abrasives to extend service intervals; model code kinPR2508-COPB-AI-SE verifies this specific piggyback coilover configuration.
• Shipping Specifications: Includes package dimensions of 38 x 7 x 5 inches and a weight of 30 pounds, aiding installers in planning workspace clearance and verifying that the suspended mass matches expected handling changes before unboxing.

Upgrading to a piggyback design prevents the pressure spikes and fading common in monotube designs when traveling deep strokes repeatedly, ensuring pedal-firm feel whether empty or loaded. The swivel end mechanism protects steering linkage geometry by maintaining parallelism under hard cornering and articulation, a common issue with rigid drop spacers or fixed-length replacement shocks. Because spring rates dictate initial ride quality alongside valving, confirm your desired lift amount and typical cargo load before installing to verify the coilover setup aligns with your chassis targets.
