QA1 10HTBF450 High Travel Tapered Coil Spring 450 lb/in 10 Inch

The QA1 10HTBF450 is a tapered Pro Coil spring designed for immediate response, increased stability, and enhanced cornering abilities. This high travel coil spring features a 450 lb/in spring rate, 4.125-inch inner diameter, and 10-inch length with tapered ends.

Advanced Engineering:

• Manufactured from high-tensile chrome silicon alloy spring wire with fewer coils and smaller wire diameter, resulting in lighter springs with increased travel due to larger distance between coils
• Reduces unsprung weight and reacts faster, optimizing suspension performance
• High-grade material with careful heat-treating and post-processing allows for greatly improved fatigue life
• Coil design allows compression to coil-bind without affecting spring rate or free height

Quality Construction:

• Durable silver powder coat finish
• Ground at both ends for straight, consistent and accurate operation
• Cold wound, heat treated, and shot peened for consistency, accuracy and durability
• Clearly marked with free length and spring rate for quick identification
• Proudly made in the USA

All QA1 springs are lifetime guaranteed to remain within 2% of the original free height and rate under normal operating conditions. Pro Coil Springs are not a direct OE replacement and are only compatible with suggested makes and models which utilize QA1 Pro Coil Systems.
