D2 Racing D-JA-01 RS Series Coilover Kit Adjustable Monotube - 36-Way

The D2 Racing RS Series Coilover Kit (D-JA-01) is D2's flagship coilover system — a proven, affordable mid-level performer that has remained a favorite among enthusiasts for over 20 years. Built around a 36-way damping adjustable monotube design, the RS Series strikes the ideal balance between responsive street performance and occasional track-day capability.

Unlike many coilover systems, the RS Series features independent ride height and spring preload adjustments, allowing precise suspension tuning without sacrificing full strut stroke. Whether you're dialing in a lowered daily driver or optimizing handling for a track event, the RS Series delivers consistent, predictable performance at every setting. Ride height can be dropped 60mm–100mm from OEM ride height.

Key Features:

• 36-way damping and rebound adjustable monotube shock assemblies
• Full ride height adjustability with separate spring preload adjustment
• Maintains full strut travel at all ride height settings
• Anodized mounts with Teflon-coated threads for corrosion resistance
• Front and rear aluminum top mounts with rubber bushings
• Fork-style front lower mount (FLM)
• Springs constructed from SAE9254 steel to resist deformity
• 6061 aluminum components for lightweight, rust-resistant construction
• Serviceable in the USA
• 1-year manufacturer's warranty

Note: This kit (D-JA-01) includes a fork-style front lower mount. Verify your vehicle's lower mount style before ordering.
