how to lift a trailer with leaf springs

Lifting a trailer with leaf springs is a process that involves modifying the suspension system to provide increased ground clearance. This can be useful for towing on rough terrain or accommodating larger tires. Here’s how you can lift a trailer with leaf springs:

Tools and Materials You’ll Need:

  • Jack stands
  • Hydraulic jack
  • Wrench set
  • Replacement leaf springs (if necessary)
  • U-bolts and brackets (if necessary)
  • Spring shackles (if necessary)
  • Safety goggles and gloves


  1. Safety Precautions:
    • Ensure that the trailer is parked on a stable, level surface, and engage the parking brake to prevent it from rolling.
  2. Assess the Existing Leaf Springs:
    • Inspect the current leaf springs on the trailer to determine their condition and capacity. Check for signs of wear, damage, or sagging. If they are in good condition and rated for your needs, you may only need to make adjustments. However, if they are worn or insufficient, consider replacing them with heavier-duty leaf springs.
  3. Jack up the Trailer:
    • Use a hydraulic jack to lift one side of the trailer off the ground. Place jack stands under the frame to support the trailer securely. Ensure that the trailer is stable before proceeding.
  4. Remove the Wheels:
    • To access the leaf springs, remove the wheels on the side you are working on. This will provide easier access to the suspension components.
  5. Adjust the Leaf Springs (Optional):
    • If your trailer has adjustable leaf springs, you may be able to lift it by altering the spring shackles or adding or removing leaf spring leaves. This adjustment depends on the design of your leaf spring suspension. Refer to the manufacturer’s instructions or seek professional guidance if necessary.
  6. Install Lift Blocks (If Necessary):
    • To achieve additional lift, you can install lift blocks between the axle and leaf springs. Lift blocks are typically made of steel or aluminum and come in various thicknesses to provide different levels of lift. Ensure that the lift blocks are compatible with your trailer’s suspension system and rated for the additional weight.
  7. Replace Leaf Springs (If Necessary):
    • If your existing leaf springs are insufficient or damaged, consider replacing them with a set that provides the desired lift. Make sure the replacement springs are designed for your trailer’s weight capacity.
  8. Install U-bolts and Brackets (If Necessary):
    • Depending on the lift block or leaf spring replacement, you may need to install new U-bolts and brackets to secure the axle to the leaf springs and lift blocks.
  9. Reattach the Wheels:
    • Once the suspension modifications are complete, reattach the wheels and tighten the lug nuts to the manufacturer’s specifications.
  10. Repeat on the Other Side:
    • If you’re lifting both sides of the trailer, repeat the above steps on the opposite side.
  11. Test the Trailer:
    • Carefully lower the trailer back to the ground, remove the jack stands, and test the trailer’s stability and handling. Ensure it’s level and doesn’t have any unusual vibrations or handling issues.
  12. Check and Adjust Alignment:
    • After lifting the trailer, it’s essential to check the wheel alignment to ensure proper tracking and tire wear. Adjust the alignment as needed.

Always prioritize safety when working on your trailer’s suspension system. If you’re not comfortable performing these modifications yourself, consider seeking assistance from a professional trailer mechanic who can ensure that the modifications are done correctly and safely.
