King 25001-389 Rear 2.5 Diameter Piggyback Reservoir Shock Set

The King Shocks 25001-389 is a pair of rear 2.5-inch diameter piggyback reservoir shocks from King's OEM Performance Upgrade line. These shocks are engineered as a bolt-on suspension upgrade, delivering race-inspired damping performance in a direct-replacement package.

Performance Engineering:

King's OEM Performance shocks are designed to maximize wheel control by damping every inch of shock movement in a smooth, calculated manner. Each unit has been developed through extensive dynamometer lab testing and real-world validation to produce an optimal damping curve. The piggyback reservoir design significantly improves heat dissipation compared to internal reservoir shocks, reducing fade during aggressive or prolonged use.

Key Features:

• 2.5" precision-bored shock body for increased fluid capacity and consistent damping
• Piggyback reservoir made from hard-anodized 6063 aluminum alloy for superior heat management and corrosion resistance
• 7/8" hard-chromed, heat-treated, micro-polished shaft for maximum durability and surface hardness against debris
• Heat-treated 6061 aluminum alloy piston for lightweight strength
• Cadmium-plated chromoly shock bodies for long-term corrosion protection
• Teflon-lined spherical bearings with misalignment capability for precise, low-friction articulation
• Custom valve adjustable with simple hand tools
• Fully rebuildable and serviceable design
• Hand-built in the USA to precise tolerances

What's Included:

• Pair of 2.5" King OEM Performance rear piggyback reservoir shocks
• Teflon-lined spherical bearings with misalignment spacers
• All necessary mounting hardware
• Installation instructions

King Shocks are hand-assembled by experienced technicians and engineered to outlast factory suspension components. The completely serviceable design allows for full rebuild after years of extreme use, making this a long-term investment in ride quality and off-road capability.
