Long awaited by Alfa enthusiasts – our newly developed reaction triangle. Finally, lightweight construction and extreme load capacity combined. No more compromises in stability, axle guidance and driving precision.
The design was developed as a robust lightweight solution for high suspension loads and is based on the construction of the original GTA reaction triangle. The component was specifically engineered for maximum stability, precise axle guidance and long-term durability.
A high-strength metal bushing is integrated in the area of the Uniball mounting to ensure maximum load capacity.
Load test:
The reaction triangle was loaded with up to 3 tonnes on both sides in a specially designed test fixture – without visible deformation or any change in geometry.
Technical specification:
• Reaction triangle in non-perforated design made from high-strength aluminum
• Bushing housings also made from high-strength 70/75 aluminum
• Plug & Play design for precise installation
• Precision-manufactured components for stable axle guidance
• Weight optimized to approx. 5 kg compared with approx. 8 kg for the original standard part
Advantages:
• Improved rear axle guidance
• More precise handling during load changes
• Greater stability at the limit
• Improved traction through more controlled axle movement
• Particularly suitable for sporty road cars, historic race cars and high-quality GTA/GTAm builds
Scope of delivery:
• Aluminum reaction triangle, non-perforated version
• Rubber bushing
• Mounting bolts
• 20 adjustment shims for the Uniball area
• 6 spacers for the bushing housings: 2 × 3 mm, 2 × 2.5 mm, 2 × 1.5 mm
