The Add-a-Leaf helper springs are one of the oldest and most common ways to increase the weight capacity of a Chevy Blazer, Jimmy, or Suburban. They are simply a specially formed leaf designed to be inserted right into the existing leaf spring. Add a Leafs are also often one of the only alternatives when adding weight capacity to a vehicle that has an OEM or aftermarket helper spring above the existing leaf spring because they will not take up any room under the chassis, other than the additional thickness of the leaf itself.

  • Level Load Capacity: 1,000 lbs.
  • Makes the existing leaf spring stronger
  • Cost effective spring solution
  • Makes your "Heavy Load" driving safer
  • Includes all necessary mounting hardware
  • Takes up no room under the chassis
  • Sold as a PAIR (both left and right)
  • DO NOT attempt to “build up” a taper spring unless using and extra taper leaf specifically designed for that purpose. “T-Places” or repair plates should not be used to increase the capacity of a taper spring under any circumstances. Never exceed the gross vehicle weigh recommendation (GVWR) of any vehicle.

The springs work great. They were simple to put on and so far have been able to handle the loads on my trailer. Still have not hauled my camper , but think they should work just fine.
