Conventional Spring 16in x 5in 100lb Bullet Proof

The Conventional Spring 16in x 5in 100lb Bullet Proof from SWIFT SPRINGS is engineered for builders and mechanics who demand precision load management in suspension systems where weight distribution, ride height, and handling response are mission-critical. This heavy-duty coil spring is designed for vehicles requiring elevated load capacity without compromising ride quality—ideal for lifted trucks, chassis modifications, and high-performance off-road builds.

Built with a 100 lbs/inch spring rate, this conventional coil spring delivers consistent compression and rebound characteristics across its 16-inch compressed length and 5-inch coil diameter, providing predictable suspension geometry during acceleration, braking, and cornering. The "Bullet Proof" designation indicates reinforced construction designed to withstand extreme axle articulation and constant-load cycling without permanent deformation or loss of spring rate.

This spring excels in lifted truck platforms, trailer-towing setups, and custom chassis builds where load support must be paired with responsive handling. Mechanics and fabricators commonly pair 100 lbs/inch springs with adjustable coilover systems or dual-spring setups for enhanced performance.
