The Kyosho VZW433 Aluminum Rear Bulk Upper Set strengthens the rear section of V ONE R4 cars to improve responsiveness. Constructed from quality aluminum, it helps keep suspension geometry stable under load.
Compatible with V ONE R4 Evo, R4, and R4s models, this aluminum rear bulk upper is machined for accurate alignment. That precision reduces unpredictable flex and makes lap-to-lap handling more consistent for club and national level drivers.
The anodized coating protects the component from corrosion while adding a tidy, professional look. It is designed to withstand regular use without compromising mounting or clearance.
For racers wanting a firmer rear end and dependable fit, the Kyosho VZW433 Aluminum Rear Bulk Upper Set is a useful upgrade to standard V ONE R4 components.
