King PR2516-SSPB-I 2.5 Performance Race Smoothie Shock Piggyback Reservoir Internal Bypass 16 Inch

The King PR2516-SSPB-I is a high-performance 2.5-inch Performance Race Series smooth body shock featuring an integrated piggyback reservoir and advanced internal bypass (IBP) technology. Designed for serious off-road applications, this shock delivers position-sensitive damping that provides superior control over high-speed and low-speed suspension movements. The smooth body design is engineered for use with existing coil springs, torsion bars, or leaf springs, making it a versatile upgrade for demanding terrain.

Key Features:

• 2.5-inch smooth body design with precision honed cylinder bores
• Internal Bypass (IBP) technology for position-sensitive damping control
• Integrated piggyback reservoir for increased oil capacity and reduced fade
• 16 inches of travel with 26-inch collapsed length and 42-inch extended length
• 6061 aluminum alloy piston for lightweight strength
• Hard-chromed shaft with 100,000 PSI tensile strength
• Teflon-lined stainless steel spherical bearings for precise articulation
• Heat-treated stainless alloy valve shims for consistent performance
• 7/8-inch shaft diameter with 1/2-inch ID heim joint mounting
• Fully serviceable and rebuildable with simple hand tools
• Hand-built in the USA to King's exacting quality standards

King's smooth body shocks are built from the same premium materials and manufactured to the same tight tolerances as their top-tier Pure Race Series. The internal bypass design eliminates external bypass tubes while maintaining sophisticated position-sensitive damping characteristics, offering enhanced control, reduced driver fatigue, and sustained peak performance in the most demanding conditions.
