X4F Rear Upper Carbon Clamp, Precision CNC Machined - XRAY 301558  [XR-301558]

Rear upper clamp engineered for X4F models

This RC rear upper clamp is designed to lower rear unsprung mass while moving effective weight forward to influence vehicle balance. The design consolidates the rear body post mount into the clamp to preserve a tidy mounting footprint and keep flex bulkhead adjustability available.

Manufactured by CNC machining from quality carbon fiber, the part offers consistent dimensions to support repeatable tuning. It ships as a pair of parts and is intended where an X4F-compatible rear upper clamp is required.

Tuning impact: installing this lighter carbon clamp reduces rear mass and biases load forward. Use that change to refine rear grip, rotation tendency, and mid-corner behavior as part of broader suspension and flex tuning work.

Consider this clamp when you need a lightweight, compact rear mount that influences balance without altering suspension geometry directly; final results depend on the complete chassis setup.
