The XRAY 363311 Aluminum Rear Lower Suspension Holder is built to sharpen the handling of XB4 series cars. Machined from durable 7075 T6 aluminum, this part stands up to club racing and carpet tracks while allowing precise setup changes for high-traction conditions.
This holder uses Integrated Suspension Settings (I.S.S.) to let you change suspension geometry without hassle. Adapted from earlier XB8 designs to suit 1/10 scale XB4 models, the system works with eccentric bushings and extra shims to give full control over roll center and toe for improved cornering and balance.
Ideal for racers and dedicated hobbyists, the XRAY 363311 offers a strong, adjustable solution to refine rear suspension response and stability on demanding high-traction tracks.
