Leaf Spring Axle U-Bolt & Tie Plate Kit – 2" x 3" Axle – 300-015976

Axle to Leaf Spring Mount Kit 2" x 3" Axle C5 Springs 300-015976

EZ Loader Trailer Axle-to-Leaf-Spring Mounting Kit

The Axle to Leaf Spring Mount Kit 2" x 3" Axle C5 Springs 300-015976 is used on compatible EZ Loader trailers to attach one 2" x 3" axle to two C5 leaf springs. This kit includes the hardware needed for one axle-to-spring mounting setup.

This kit is used in the trailer suspension area where the axle, leaf springs, U-bolts, tie plates, and mounting hardware work together to clamp the spring assembly to the axle. Correct fitment matters because the axle size, spring type, U-bolt spacing, tie plate layout, and trailer application must match.

Important fitment note: This kit is for compatible EZ Loader trailers using a 2" x 3" axle with C5 leaf springs. Do not match this kit by appearance alone. Confirm your axle size, spring type, existing hardware, and trailer application before ordering.

Typical EZ Loader Trailer Applications

This axle to leaf spring mount kit may be used on compatible EZ Loader boat trailers with a 2" x 3" axle and C5 leaf springs. Common service situations include axle replacement, leaf spring replacement, U-bolt replacement, tie plate replacement, and suspension repair.

Because EZ Loader trailers use different axle sizes, spring types, U-bolt lengths, tie plates, and mounting layouts by model and production year, always compare the existing hardware before ordering.

Why the Axle-to-Spring Mount Kit Matters

The axle-to-leaf-spring mounting hardware carries important clamping load between the trailer axle and the leaf springs. The U-bolts, tie plates, nuts, axle, and springs must work together to hold the suspension assembly securely under load.

If the U-bolts are stretched, nuts are worn, tie plates are bent, or hardware is badly corroded, the axle may not stay properly clamped to the spring assembly. Replacing questionable axle mounting hardware during suspension service can help restore a more secure axle-to-spring connection.

2" x 3" Axle and C5 Spring Fitment

This kit is intended for compatible EZ Loader trailer applications using a 2" x 3" rectangular axle with C5 leaf springs. Both details matter.

Do not rely on axle appearance alone. Confirm the axle dimensions, spring type, U-bolt layout, tie plate hole spacing, and existing hardware before ordering. If your trailer uses a different axle size or spring type, this may not be the correct kit.

Kit Coverage: One Axle to Two Leaf Springs

This kit includes hardware to attach one axle to two leaf springs on compatible EZ Loader trailer applications. That normally covers one axle mounting setup across both left-hand and right-hand spring locations.

If servicing more than one axle, confirm whether additional kits are required before ordering.

Installation Considerations

• Confirm this kit matches part number 300-015976.
• Confirm the trailer uses a compatible 2" x 3" axle.
• Confirm the trailer uses compatible C5 leaf springs.
• Inspect the axle, leaf springs, tie plates, U-bolts, nuts, spring seats, and related suspension hardware before reassembly.
• Replace worn, stretched, rusted, bent, cracked, or damaged mounting hardware before towing.
• Do not reuse U-bolts that are stretched, heavily corroded, damaged, or have compromised threads.
• Confirm U-bolt orientation, tie plate placement, and axle-to-spring seating before tightening.
• Tighten suspension hardware to the proper specification for the trailer application.
• Recheck suspension hardware after service and after initial towing.

Axle to Leaf Spring Mount Kit Fitment Guidance

This is not a universal trailer suspension kit.

• Confirm the trailer is a compatible EZ Loader application.
• Confirm the part number is 300-015976.
• Confirm the axle size is 2" x 3".
• Confirm the trailer uses C5 leaf springs.
• Confirm U-bolt size, tie plate layout, spring width, and mounting location.
• Compare the old hardware and mounting area before ordering.
• Use photos, measurements, trailer VIN, and existing part details when checking fitment.

Real-World Insight

Axle-to-spring mounting hardware is one of the most important clamping points in a leaf spring trailer suspension system. If the axle is not clamped correctly to the springs, the suspension may shift, track poorly, make noise, or cause uneven tire wear.

When servicing springs, axles, U-bolts, or tie plates, inspect the full axle-to-spring mounting area carefully before reusing old hardware.
