Add tunable damping without changing the vehicle's spring system
King Shocks PR2512-SS-A is a universal 2.5-inch Performance Race smooth-body shock for custom suspension applications that need 12 inches of travel and externally adjustable compression damping. Its hose-mounted reservoir helps separate the oil and gas volume while allowing flexible reservoir placement.

- 2.5-inch Performance Race smooth-body construction
- 12-inch stroke
- Hose-mounted remote reservoir
- External wide-range compression adjuster
- 150 psi published gas pressure
- Rebuildable and tunable design

FAQ
What is the PR2512-SS-A?It is one universal 2.5-inch Performance Race smooth-body shock with a 12-inch stroke, hose-mounted remote reservoir, and external compression adjuster.
Is this shock vehicle specific?No. It is a universal fabrication component. The installer must verify travel, compressed and extended lengths, mounting interfaces, reservoir placement, hose routing, and clearance.
How many shocks are included?One shock assembly is supplied. A second shock is not included.
What are the compressed and extended lengths?King publishes a 20.596-inch compressed length and a 32.597-inch extended length.
What does the compression adjuster do?The external adjuster changes compression damping from softer to firmer settings for changing load and terrain requirements.
What supports the vehicle weight?This is a smooth-body damper. Existing leaf springs, torsion bars, coils, or another correctly engineered spring system must support the vehicle.
Is the shock serviceable?Yes. King describes its Performance Race shocks as rebuildable and tunable, but service and nitrogen charging require correct procedures and equipment.
What must be checked before final installation?Cycle the suspension through full travel and steering movement, then confirm the shock cannot bottom, top out, bind, contact the chassis, or strain the reservoir hose.
Installation Instructions
- Measure the suspension through full compression, droop, and steering movement to confirm the required shock stroke and mounting position.
- Confirm the 20.596-inch compressed and 32.597-inch extended lengths leave safe reserve travel before fabricating mounts.
- Verify the spring system supports the vehicle and that the shock will not be used as a suspension stop or structural limit.
- Plan a protected reservoir location with sufficient hose bend radius, service access, and clearance from heat, tires, steering, and moving suspension parts.
- Position the shock without side-loading, then tack or temporarily secure the mounts using a qualified fabrication process.
- Cycle the complete suspension and steering system again to confirm the shock cannot bottom, top out, bind, contact the chassis, or strain the hose.
- Finish the mounts, install the shock and reservoir, and torque all hardware to the applicable component and fabrication specifications.
- Set the compression adjuster to a conservative initial position, road-test at low speed, and inspect all mounts, hose routing, and fasteners after the first operating interval.
