RADTEC aluminium side spring retainers are intended to improve suspension reliability on XRAY X1 cars. Manufactured from robust aluminium, they help maintain spring position and reduce unwanted movement under load.
These retainers are tailored to fit earlier XRAY X Series versions and offer a tight fit that reduces play in the spring assembly. They are suitable for track sessions or general hobby use where consistent suspension action is needed.
Aluminium is widely used for upgrades because it blends lightness with strength. These retainers assist in preserving constant spring tension, which contributes to steadier steering response and cornering balance.
