The GPM Aluminum Front/Rear Upper Chassis Link Parts are designed to replace less rigid stock components and provide a measurable increase in chassis stiffness for AXIAL SMT10 and Yeti platforms. These precision engineered aluminium links improve resistance to flex under load, helping to preserve intended suspension geometry and deliver crisper handling during technical driving. Ideal for hobbyists looking for a durable upgrade that supports consistent setup changes and tuning adjustments.
