Street & Track Coilovers with Height and Compression Adjustment – JS Suspension – fits Volvo SPA models

Performance-focused suspension upgrade with adjustable comfort

JS Suspension V3 coilovers are developed for Volvo SPA platform vehicles equipped with rear composite leaf spring suspension. This kit upgrades the front suspension with fully adjustable coilovers, while the rear features performance dampers combined with adjustable leaf spring spacers for ride height tuning.

Designed for both everyday driving and performance use, the system allows drivers to fine-tune ride height, damping characteristics and overall driving balance.

V3 Coilovers – Adjustable for Performance and Comfort

The JS Suspension V3 system features a threaded lower damper mount enabling independent ride height and spring preload adjustment. Damping hardness can be adjusted via a top-mounted adjustment knob with 32 steps of compression adjustment, allowing precise setup depending on driving style and road conditions.

Whether used for street driving, spirited cruising, track days or more dynamic driving, the system provides improved control and responsiveness.
