RS3016-COPB-AI-SE 3.0 RS Coil-Over Shock W/Piggyback Res, Swivel EC & Adjuster (IBP) 16" Stroke

King’s Pure Race coil-over shocks are engineered for strength, precision, and consistent performance under extreme conditions, using specialized machining and hardware to ensure smooth adjustments and long‑term durability.

• Truncated thread shock bodies provide exceptional strength and allow trouble free spring adjustments.


• Three piece adjusting nut assembly uses a unique pinch bolt design for superior clamping force without damaging threads like set screw style collars.


• Upper spring centering ring and nylon anti friction disc makes adjusting even heavily preloaded springs quick and smooth.


• Billet nylon coil sliders maintain proper spring alignment, operate silently, and withstand temperatures up to 450°F.


• Dual rate spring hardware uses lockable secondary nuts to allow precise tuning of secondary spring engagement.
