King 25001-374A Rear 2.5" Piggyback Reservoir Shock with Adjuster 0-2" Lift

The King Shocks 25001-374A is a rear OEM Performance piggyback reservoir shock absorber featuring a 2.5-inch diameter shock body and an integrated compression damping adjuster. Designed for lifted applications supporting 0–2.0 inches of rear lift, this shock delivers race-bred performance in a direct bolt-on package.

Key Features:

• 2.5" precision-bored shock body increases fluid capacity for smoother, more consistent damping
• Piggyback reservoir dramatically increases fluid volume and heat dissipation, providing sustained damping performance under demanding conditions
• Finned reservoir design for enhanced heat management and reduced fade
• External compression damping adjuster allows fine-tuning of ride quality and handling for your chosen terrain
• Supports 0–2.0" of rear lift for lifted suspension applications
• Built from aircraft-quality billet aluminum components with a heat-treated 2024 aluminum alloy piston
• 7/8" hard-chromed, heat-treated, micro-polished shaft with extremely high tensile strength for resistance against debris and wear
• Cadmium-plated chromoly shock body construction
• Fully rebuildable, serviceable, and tunable — built to the same tolerances as King's Pure Race series
• Hand-built in the USA by experienced King Shocks technicians

What's Included:

• Rear shock absorbers with piggyback finned reservoirs (pair)
• All necessary mounting hardware

King Shocks OEM Performance shocks undergo extensive dynamometer lab testing and real-world validation to develop the optimal damping curve for each specific application. The result is a bolt-on suspension upgrade that elevates both on-road comfort and off-road capability.
