The RAD-XR-10003 Aluminum Lightweight Spring Retainers are made for older T Series XRAY models and provide a practical suspension upgrade. Machined from lightweight aluminum, these retainers add minimal weight while helping you dial in more accurate spring seating and travel control.
These retainers let you tweak spring position and preload without changing the car balance noticeably. Their low weight makes them a good choice for racers and weekend drivers who want dependable spring support without adding bulk. Use them when refining a race setup or improving on-track consistency.
Designed for the XRAY Vintage Series and older T Series chassis, these retainers slip into place for a secure fit and straightforward installation. Compared with stock plastic parts, the aluminum construction gives better durability and a longer lifespan under regular use.
