King RS4526-BP7P 4.5" Pure Race Bypass Shock 7-Tube Piggyback 26" Stroke 1.25" Shaft

The King RS4526-BP7P is a 4.5-inch Pure Race Series bypass shock engineered for extreme off-road racing applications. This premium shock features a 7-tube bypass configuration with piggyback reservoir design, delivering 26 inches of stroke length for maximum suspension travel in unlimited race vehicles and high-performance pre-runners.

Key Features:

• 4.5-inch shock body diameter for increased oil volume and superior heat dissipation
• 7-tube bypass configuration with large 1.00-inch bypass tubes for position-sensitive damping
• Oversized 1.25-inch induction-hardened shock shaft, hard chrome plated and micro-polished to 3 RMS finish
• 26-inch stroke length ideal for long-travel suspension systems
• Piggyback reservoir design with threaded end caps for high-pressure resistance and ease of maintenance
• Precision-bored 4130 chromoly shock body honed to +/- .001 inch tolerance
• Heat-treated 2024 aluminum alloy piston with advanced port configurations
• Lightweight hard-anodized 6063 aluminum alloy reservoir for rapid heat dissipation
• Independently adjustable bypass stages for precise tuning control
• Designed to withstand temperatures up to 450 degrees Fahrenheit

Built to dominate the world's toughest races including the Baja 1000 and Dakar Rally, King's Pure Race Series shocks represent the pinnacle of off-road shock technology. Each bypass stage is separately tunable and operates independently, providing unmatched control over high-speed and low-speed oscillations. The gapless PTFE-impregnated bronze wear band creates a double seal that optimizes valving function and allows the final compression stage to act as a hydraulic bump stop.

King's advanced manufacturing process includes CNC-drilled bypass ports that are hand-deburred and polished for unrestricted fluid flow. The heat-treated stainless alloy valve shims maintain consistent damping performance at extreme temperatures without fracturing. Every aspect of this shock has been optimized for brutal strength, precision adjustability, and championship-level performance in the most demanding racing conditions.
