Pro-Kit springs
These are a moderate progressive-rate lowering spring. At ride height, the rate is less than 10% higher than the stock spring rate. However, the progressive design causes the spring rate to increase as the spring compresses, allowing both a lower rate for very good ride quality and a higher rate as the spring compresses to better limit body roll and brake dive. Excellent for daily driving.

Approximate lowering

• 2003-2004 Cobra hardtop with IRS: (Front: 1.0", Rear: 1.4")
• 2003-2004 Cobra convertible with IRS: (Front: 1.0", Rear: 1.4")

For best performance and ride quality these springs should be matched with an appropriate set of struts and shocks. Read the Installation tab.
