TEIN VSQ36-M1AS3 RX1 Coilover Kit with Hydraulic Bump Stop

The TEIN VSQ36-M1AS3 RX1 Coilover Kit delivers exceptional ride comfort and handling performance through advanced twin-tube suspension technology. Engineered specifically for enthusiasts who demand both street comfort and responsive handling, this complete coilover system represents TEIN's commitment to quality suspension engineering.

Hydraulic Bump Stopper Technology:

The RX1 series features TEIN's exclusive Hydraulic Bump Stopper (H.B.S.) system, proven effective in World Rally Championship and European Rally Championship competition. Unlike traditional rubber bump stops that create harsh upward jolts, the H.B.S. converts impact energy into thermal energy, absorbing big impacts smoothly without rebound force. This technology ensures comfortable ride quality even at full occupancy or when traversing rough road conditions.

Key Features:

• 16-level damping force adjustment for simultaneous compression and rebound tuning
• Full-length ride height adjustment with minimal effect on ride quality
• Adjustable ride height range: Front 0.4" to 2.4" lower, Rear 0.3" to 2.8" lower
• Spring rates: 224 lb/in front, 280 lb/in rear
• Twin-tube structure for longer strokes with reduced repulsive force
• Pillow ball upper mounts with front camber plates included
• Adjustable camber lower bracket for precise alignment tuning
• High-spec damper oil maintains stable viscosity across temperature ranges
• No-sag springs cold-formed from SAE9254 steel (minimum tensile strength 200 kgf/mm²)

Superior Durability:

TEIN's proprietary ZT Coating provides exceptional protection against chipping from road debris and corrosion. Upper mounts and lower brackets feature TEIN's patented 2-layer/1-bake powder coating process for superior rust resistance. With zero claims for rust-related issues across 500,000 dampers sold, these coilovers are ideal for coastal areas and snowfall regions.

Complete Kit Includes:

• 4 shock absorbers with Hydraulic Bump Stoppers
• 4 coilover springs with powder-coated finish
• Exclusively designed upper mounts with front camber plates
• Camber-adjustable lower brackets
• Optimally-shaped dust boots for piston rod protection

The TEIN RX1 system is compatible with EDFC electronic damping force controllers (sold separately) for convenient in-cabin adjustment. Manufactured and assembled in TEIN's Yokohama, Japan facility, this coilover kit is backed by TEIN's reputation for quality and is available for professional overhaul and revalving services.
