King 25700-413A 2.5 IBP Internal Bypass Rear Shock Kit with Compression Adjuster

The King Shocks 25700-413A is a 2.5" Internal Bypass (IBP) rear shock kit engineered as a high-performance OEM-style upgrade. Custom-tuned and subjected to real-world testing to develop an optimal damping curve, this kit delivers a significant step up in ride quality and capability over factory shocks.

• 2.5" IBP Internal Bypass Technology: Delivers precisely tunable velocity-sensitive and position-sensitive damping, along with a hydraulic bump stop, all in a bolt-on monotube package
• Wide Range Compression Adjuster: Included standard — allows precise compression damping adjustment to fine-tune ride quality on demand
• Large 2.5" Diameter Shock Body: Increases fluid capacity for smoother, cooler shock operation under demanding conditions
• Monotube Design: Features a full-diameter piston with standard, full-size valving — built to the same tolerances as King's top-of-the-line Pure Race series shocks
• Extended Travel: Increases available wheel travel for improved off-road performance
