Barrel Spring 16in x 2.5in 175#

The Barrel Spring 16in x 2.5in 175# by Swift Springs is engineered for builders and mechanics seeking precise suspension tuning and load support in custom automotive applications. This coil spring delivers consistent force control in lift kits, lowering systems, and performance suspension setups where predictable spring rate and consistent load handling are non-negotiable. Whether you're building a dedicated off-road rig, creating a level-ride truck platform, or fine-tuning a street car's suspension geometry, this spring provides the engineering foundation to achieve your chassis dynamics goals.

Swift Springs manufactures this barrel-profile coil with a 175-pound spring rate—a mid-range specification ideal for vehicles supporting moderate payload without excessive stiffness that would compromise ride quality on irregular surfaces. The 16-inch length and 2.5-inch outer diameter are industry-standard dimensions compatible with most coil-over platforms and factory suspension towers, minimizing custom fabrication requirements. The barrel profile design reduces coil bind risk and improves spring stability under dynamic load cycling, making this specification reliable for both street duty and weekend track work where repetitive compression cycles stress standard linear springs.

Mechanics and fabricators benefit most from this spring when pairing it with matching damper selections—a 175# rate typically pairs well with mid-range shocks calibrated for street-performance applications. Verify mounting boss diameter and suspension tower clearance before installation; the 2.5-inch OD accommodates standard coil-over sleeves and most OEM tower designs. This spring functions effectively in dual-spring setups, progressive suspension systems, or as a replacement unit in lifted or lowered platforms, provided companion springs and dampers maintain compatible rates for balanced geometry and handling.
