King PR2510-SSPB-I 2.5 Performance Racing Smoothie Shock with Piggyback Reservoir and IBP 10 Inch Stroke

The King PR2510-SSPB-I is a high-performance 2.5-inch diameter smooth body shock absorber featuring an integrated piggyback reservoir and advanced IBP (Internal Bypass) technology with a 10-inch stroke. Designed for serious off-road enthusiasts and racing applications, this shock delivers precisely tunable velocity-sensitive and position-sensitive damping along with an integrated hydraulic bump stop in a bolt-on monotube design.

Key Features:

• 2.5-inch diameter smooth body construction for increased fluid capacity and superior heat dissipation
• 10-inch stroke length with compressed length of 18.375 inches and extended length of 28.375 inches
• Piggyback reservoir design for enhanced cooling and consistent damping performance
• IBP (Internal Bypass) technology provides position-sensitive damping and hydraulic bump stop functionality
• 7/8-inch shaft diameter with 1/2 x 1.50-inch mounting hardware
• 150 PSI gas pressure for optimal performance across varying terrain
• Built from aircraft-grade 6061-T6 aluminum construction
• Fully rebuildable, serviceable, and tunable for custom applications

The IBP internal bypass system features secondary valving mounted below the primary piston that allows fluid to flow through the shock's hollow shaft, creating light valving at ride height for comfortable daily driving while providing substantial damping force at full compression to prevent bottoming out during aggressive off-road use. This shock is designed to work with existing coil springs, torsion bars, or leaf springs, making it an ideal upgrade for trucks, SUVs, and pre-runner applications. Hand-built in the USA to King's exacting standards, each shock undergoes extensive dynamometer testing and real-world validation to ensure fade-free performance and long service life.
