Conventional Rear Spring 14in x 5in x 275lb

The Conventional Rear Spring 14in x 5in x 275lb from SWIFT SPRINGS is a heavy-duty coil spring engineered for vehicles requiring increased load capacity and improved ride stability. This rear spring is ideal for pickup trucks, SUVs, and work vehicles that regularly carry payload or tow trailers. Built to OEM or aftermarket specifications, it restores factory ride height and handling characteristics when stock springs have sagged, making it essential maintenance for any serious enthusiast or fleet operator seeking reliable suspension geometry.

With a 275-pound spring rate and 14-inch body length paired with a 5-inch seating diameter, this conventional coil design provides controlled compression and rebound damping that works seamlessly with factory or upgraded shock absorbers. The robust construction minimizes deflection under load, maintaining consistent suspension angles critical for tire wear, brake bias, and handling predictability. Precision wound construction ensures uniform load distribution across coils, preventing premature fatigue cracking and extending service life even in demanding applications involving heavy towing or off-road use.

Mechanics and restoration specialists frequently specify SWIFT SPRINGS coils for chassis rebuild projects, load-leveling upgrades, and suspension rehabilitation. This spring pairs effectively with dual-rate or variable-rate shock packages and integrates with both leaf-spring and multi-link rear suspensions found in modern trucks. Installation requires basic spring tools and proper vehicle support; always compress springs safely using coil compressors and follow manufacturer torque specifications for mounting hardware to ensure safety and longevity.
