Fits select 2011-2019 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD.

The Hellwig LP-35 Load Pro helper spring is the workhorse of the Hellwig line, designed specifically for fleet applications and heavy-duty trucks that consistently haul or tow near their maximum capacity. Featuring a 4-leaf stack and a full-time spring rate design, this system provides constant support to maintain a level ride height, improve stability, and reduce sag under heavy loads.

The Load Pro series is fully tunable, allowing you to adjust the spring rate to match your specific loading requirements. This unit replaces the standard leaf pack's tendency to bottom out, making it an essential upgrade for 1-ton and 3/4-ton work trucks. Please note that an LP mounting kit is required for installation (sold separately).
