FAQ
What is the PR2508-STNR?It is one universal 2.5-inch Performance Race steering stabilizer with an 8-inch stroke and neutral Balanced Flow piston design.
Is this stabilizer vehicle specific?No. It is a universal fabrication component, so the installer must verify mounting width, bolt size, compressed and extended lengths, steering travel, and clearance.
How many stabilizers are included?One steering stabilizer is supplied.
What is the compressed length?King publishes a compressed length of 15.971 inches for the exact configuration.
What is the extended length?King publishes an extended length of 23.973 inches.
What is Balanced Flow technology?King describes a steering-specific piston that helps reduce unwanted steering input while allowing the piston to remain neutral around center.
Is the stabilizer rebuildable?Yes. King Performance Race components are serviceable and tunable with replacement parts available, but service requires the correct procedures and equipment.
Can it be mounted before cycling the steering?No. Cycle the steering and suspension through their full ranges before final mounting to prevent binding, bottoming, topping out, or contact.
Installation Instructions
- Measure the steering system through full left and right lock and the suspension through its travel to determine the required stabilizer stroke and mounting location.
- Confirm the 15.971-inch compressed and 23.973-inch extended lengths leave safe reserve travel in both steering directions.
- Verify mounting width, bolt diameter, bracket strength, linkage movement, tire clearance, and access before drilling, welding, or clamping any mount.
- Position the stabilizer near the neutral midpoint of its stroke with the steering centered, then tack or temporarily secure the brackets.
- Cycle the steering and suspension again to confirm the stabilizer cannot bottom, top out, bind, contact the chassis, or become the steering stop.
- Complete the mounts using a qualified fabrication process, install the stabilizer without side-loading, and torque the hardware to the applicable specifications.
- Road-test at low speed, verify free return-to-center behavior, and recheck all mounts and fasteners after the initial driving interval.
