Hellwig Load Pro Helper Springs

Hellwig's Load Pro Helper Springs are a easy and effective way to add level load carrying capacity. These kits are available in three different levels, allowing you to customize based upon your needs.

Hellwig LP-15

This spring is designed to provide up to 1,500 lbs. to your level load carrying capacity for full-size pickups, vans sport utility vehicles and motor homes. The progressive load action design gives you leveling adjustability for additional load carrying assistance when hauling occasional loads; also reduce the tendency of vehicles to throw their weight around.


  • 1,500 lbs. Level Load Capacity
  • Used for Heavier Loads
  • Available in Progressive & Constant Rate**

Hellwig LP-25

For Full Size Trucks, vans, and sport utility vehicles, the LP-25 Helper Spring kits bolt-on to old or new existing factory rear leaf springs to help the suspension realize its full level load carry capacity potential, up to 2,500 lbs. Your heavy load driving becomes safer and easier with proper vehicle leveling. Driver comfort, road handling and braking are also improved.

LP-25 Helper Springs are manufactured from high quality alloy spring steel. They are hot-formed and heat-treated for extra strength and durability.

The kits come in two versions. Constant load kits for full time suspension support; ideal where loads are typically more constant, such as on contractor/commercial service trucks and motor homes. Progressive load kits can be adjusted for additional level load carrying assistance when hauling an occasional load of fire wood or towing a trailer. Factory ride and handling characteristics are unaffected when vehicle is not loaded.

  • All LP-25 and LP-35 Helper Spring Kits require a mounting kit that is sold separately. These kits are different for those with 2.5" wide leaf springs and 3" wide leaf springs. Due to manufacturer differences in production, physical inspection and measurement of your leaf springs is necessary for accurate installation.
  • Note: All Hellwig Level Load Kits are designed only to offer a level load at your vehicle's maximum gross vehicle weight rating. Never exceed your vehicle's GVWR. Adequate tire and wheel to kit clearance is required for proper installation. Call us if unsure on how to determine adequate clearance.
