King RS3512-SS Pure Race 3.5in Smooth Body Shock Absorber 12in Stroke

The King Shocks RS3512-SS is a 3.5-inch smooth body Pure Race series shock absorber featuring a 12-inch stroke, purpose-built for high-performance off-road racing and competition use. As part of King's flagship Pure Race lineup, this shock is engineered to deliver professional-grade damping performance with full rebuildability and tunability.

King Shocks designs each Pure Race shock using race-proven technology, including a cold-drawn 2024 billet aluminum piston and precision-ported valving developed through extensive fluid dynamics research. The result is consistent, fade-free damping under the most demanding conditions.

Key Features:

• 3.5-inch body diameter for increased oil volume and improved heat dissipation
• 12-inch stroke for maximum suspension travel in race applications
• Smooth body (SS) configuration — clean, compact envelope without external bypass tubes
• Large 1-inch or 1.25-inch induction-hardened shock shaft, hard chrome plated and micro-polished to a 3 RMS mirror finish
• Viton o-ring seals and carbon composite wiper seal for sustained high-temperature performance
• Stainless alloy heat-treated valve shims for consistent damping and fatigue resistance
• Shock tubes are precision bored and honed to ±0.001-inch tolerance for optimal piston seal and flow characteristics
• Assemblies are pressure tested to 300 PSI prior to shipping
• Fully rebuildable and re-valvable for long-term racing use

The RS3512-SS is custom-built and tuned for your specific application, making it an ideal choice for desert racing, pre-runner builds, and serious off-road competition where maximum performance and durability are required.
