King 25001-142A OEM Performance Rear Piggyback Reservoir Shock Absorber with Adjuster - 2.5

The King Shocks 25001-142A is a 2.5" diameter rear piggyback reservoir shock absorber with adjuster, part of King's OEM Performance series. Built to the same exacting tolerances as King's top-tier Pure Race shocks, this unit delivers a dramatic upgrade in ride quality and off-road capability over factory dampers.

The large 2.5" shock body increases fluid capacity for smoother, cooler operation, while the piggyback external reservoir further expands oil and gas volume to reduce fade and maintain consistent damping performance under demanding conditions. The external compression adjuster allows fine-tuning of damping characteristics to suit varying terrain and load conditions.

Key Features:

• 2.5" diameter shock body for increased fluid capacity and heat dissipation
• Piggyback external reservoir for sustained damping performance under punishing conditions
• External compression adjuster for on-vehicle damping tuning
• Compressed length: 16.346 in. | Extended length: 24.813 in. | Stroke: 8.467 in.
