etrailer | Dexter Trailer Springs Over-Under Conversion Kit Installation K71-384-00

Introduction

This tutorial will guide you through the installation of the Dexter Over-Under Axle Conversion Kit (K71-384-00) on your trailer. This conversion is particularly useful for increasing the ride height of your trailer, allowing for better alignment with newer, taller tow vehicles.

Step 1: Gather Necessary Tools and Materials

Before starting the installation, ensure you have the following tools and materials ready:

• Dexter Over-Under Conversion Kit (includes U-bolts, spring seats, nuts, and U-bolt plates)
• Socket set
• Jack and jack stands
• Penetrating oil (for rusted bolts)

Step 2: Remove the Trailer Tires

1. With the trailer still on the ground, use the socket set to remove the lug nuts from the tires.
2. Carefully lift the trailer using a jack and place jack stands under the frame to securely support it. Ensure the stands are evenly distributed for stability.
3. Remove the tires and set them aside.

Step 3: Prepare the Axle for Removal

1. Inspect the U-bolts and U-bolt plates. If rusted, apply penetrating oil and allow it to sit for a few minutes.
2. Start removing the U-bolts. Use a back-and-forth motion when loosening to prevent uneven tension.
3. Once both U-bolts are removed, take off the U-bolt plate.

Step 4: Support the Axle

1. Place a jack under the axle to support it, as it will be free-hanging without the U-bolts.
2. Lift slightly to relieve any tension from the leaf springs.

Step 5: Remove the Leaf Spring Bolts

1. Identify the bolt at the front of the leaf spring (towards the nose of the trailer) and remove it.
2. If the bolt is stiff, consider threading the nut back on to help pull it out without damaging the threads.

Step 6: Install the Conversion Kit

1. Position the new spring seats on the axle where the leaf springs will rest.
2. Flip the axle under the leaf springs, ensuring the U-bolts will face down after installation.
3. Align the U-bolts with the spring seats and secure them with the provided nuts.

Step 7: Reinstall the Tires

1. Once the axle is securely in place and all components are tightened, reposition the tires onto the wheel hubs.
2. Hand-tighten the lug nuts before lowering the trailer back to the ground and fully tightening them.

Conclusion

You have successfully installed the Dexter Over-Under Axle Conversion Kit. This modification should enhance your trailer's ride height and improve its compatibility with taller tow vehicles. Always ensure that your installation is secure and double-check your work before hitting the road. For further enhancements or maintenance, consider reviewing additional suspension parts or consulting with a professional.
