Speedmaster 200 lbs./in. Spring Rate 12" Coil Over Shock Springs - Silver Pair (PCE493.1005)

The Speedmaster PCE493.1005 coil over shock springs are a pair of performance-grade suspension components designed for custom and aftermarket coil-over applications. These springs feature a 200 lbs./in. spring rate and stand 12" tall, making them suitable for lowering and stiffening suspension systems on high-performance vehicles. The silver finish provides corrosion resistance and a polished appearance.

These coil over shock springs are commonly used in street performance builds, track suspension upgrades, and custom hot rod applications where precise ride height and spring rate control are critical. The 200 lbs./in. rate offers a moderate-to-stiff spring characteristic ideal for vehicles requiring improved handling response without excessive harshness. As a matched pair, they ensure consistent suspension geometry and balanced load distribution across both sides of the vehicle. Installation typically involves mounting them over shock absorbers within a coil-over suspension kit or assembly.
