The Kyosho MXW004 brass rear axle cap is a targeted upgrade for Mini-Z 4x4 crawlers that shifts mass toward the rear. It is intended to deliver steadier behaviour when negotiating slopes and technical sections.
Adding brass at the rear axle lowers and repositions the centre of gravity, helping the rear wheels retain grip on downhill runs. This can make descents easier to control and reduce unwanted rear slides.
Built for the Mini-Z 4x4 series, the Kyosho MXW004 features precise machining for correct alignment and straightforward installation. It is a clean upgrade for those seeking a practical handling improvement.
