Description
A properly seated spring cup is critical to maintaining consistent suspension geometry and load transfer during hard cornering and acceleration. The Allstar Performance L/W Steel Spring Cup delivers a lightweight, durable upper mounting point that resists deflection under high G-forces, ensuring your suspension performs predictably lap after lap. As a direct bolt-on upgrade, installation takes minutes without requiring frame modifications or professional fabrication.
