D2 Racing D-TO-71 RS Series Coilover Kit Adjustable Monotube - 36-Way

The D2 Racing RS Series Coilover Kit (D-TO-71) is D2's flagship mid-level performance suspension system — a proven, affordable choice for enthusiasts who want a genuine balance between daily street comfort and occasional track performance. Originally introduced over 20 years ago, the RS Series remains one of the most popular coilover options in its class.

Built around a 36-way damping and rebound adjustable monotube design, these coilovers deliver precise, consistent damping control across a wide range of driving conditions. The monotube construction maintains stable, accurate damping performance by keeping oil and gas separated within the shock body, resulting in reduced fade and more predictable handling.

A standout feature of the RS Series is its independent ride height and spring preload adjustment — allowing you to dial in your desired stance without sacrificing full strut travel. Unlike coilovers that adjust height through the spring perch alone, D2's system ensures the shock absorber maintains its complete range of motion at any ride height setting.

Key Features:

• 36-way damping and rebound adjustability — tune each corner independently for your driving style
• Full monotube shock design for stable, fade-resistant damping performance
• Separate ride height and spring preload adjustments — maintain full strut stroke at all lowered heights
• Front and rear units reuse OEM top mounts for a straightforward installation
• Anodized and powder-coated mounts constructed from 6061 aluminum
• Teflon-coated strut threads for corrosion and rust resistance
• Complete 4-piece kit — includes front left, front right, rear left, and rear right coilovers
• Rebuildable and fully serviceable in the USA
• 1-year manufacturer's warranty

Whether you're building a lowered street cruiser or a weekend track car, the D2 Racing RS Series coilover kit offers the adjustability and durability to support both goals without compromise.
