Axle to Spring / Guide Mounting Plate 250-031133

EZ Loader Trailer Axle, Spring, and Guide Mounting Plate

The Axle to Spring / Guide Mounting Plate 250-031133 is a replacement mounting plate used on select EZ Loader galvanized boat trailers. Depending on the trailer application, this plate may be used to help attach the axle to the leaf spring assembly or to mount certain side PVC guides, side bunk guides, or related trailer guide hardware.

This plate is found on specific galvanized EZ Loader trailer applications, including examples such as 58BS 14 800, 67BT 12-14 1200, and 68BT 14-17 1250. These examples are provided as common reference points only. Always confirm your trailer model, part number, bolt size, mounting location, and existing hardware before ordering.

Hardware note: U-bolts, nuts, and 1/2" bolts may be required depending on how this plate is being used. U-bolts and nuts are commonly required for axle-to-spring mounting. 1/2" bolts may be required for compatible side guide, side bunk guide, or spring shackle-related hardware applications. Hardware is not included unless specifically stated in the product listing.

Correct fitment matters because this plate may serve more than one purpose depending on the trailer setup. The axle size, spring layout, guide style, bolt size, hole spacing, and mounting location must match the trailer application.

Typical EZ Loader Trailer Applications

This mounting plate may be used on select EZ Loader galvanized boat trailers where this plate style is required for axle-to-spring mounting, side PVC guide mounting, side bunk guide mounting, or selected suspension hardware applications.

Common EZ Loader trailer examples may include 58BS 14 800, 67BT 12-14 1200, and 68BT 14-17 1250. These trailer models are examples only. EZ Loader trailers can vary by model year, production run, axle setup, spring layout, and guide hardware configuration.

Always compare your existing plate, bolt size, hole spacing, axle size, guide setup, and mounting location before ordering.

Axle-to-Spring Mounting Use

When used in an axle-to-spring application, this plate works with compatible U-bolts and nuts to help clamp the trailer leaf spring assembly to the axle. The axle, leaf spring, mounting plate, U-bolts, and nuts all work together to hold the suspension assembly in position.

For this use, confirm that your trailer uses a compatible 2" x 2" axle, matching U-bolts, proper nut hardware, correct spring width, and matching plate hole spacing.

Side Guide and Side Bunk Guide Use

On some compatible EZ Loader galvanized trailers, this plate may also be used as part of the side PVC guide or side bunk guide mounting setup. In these guide applications, compatible 1/2" bolts may be required depending on the trailer and guide bracket arrangement.

If you are replacing guide hardware, confirm the plate location, guide style, bolt size, hole spacing, and trailer model before ordering.

Hardware Required

This listing is for the mounting plate only unless otherwise stated. Depending on your application, you may need additional hardware.

• Axle-to-spring mounting: compatible U-bolts and nuts may be required.
• Side PVC guide mounting: compatible 1/2" bolts and nuts may be required.
• Side bunk guide mounting: compatible 1/2" bolts and nuts may be required.
• Spring shackle-related use: compatible 1/2" bolts may be required depending on application.

Always inspect and confirm the existing hardware before ordering replacement parts.

Fitment Is Based on Application, Not Plate Shape Alone

This plate can serve different purposes depending on the trailer setup. Plate shape alone does not confirm fitment.

The trailer model, axle size, guide style, bolt size, U-bolt spacing, plate hole layout, spring setup, and mounting location must all match the application. If your old plate is missing or damaged, photos and measurements are often the fastest way to confirm the correct part.

Associated / Compatible Parts

Installation Considerations

• Confirm the existing plate matches part number 250-031133.
• Confirm whether the plate is being used for axle-to-spring mounting, side PVC guide mounting, side bunk guide mounting, or another approved trailer hardware application.
• For axle-to-spring use, confirm the axle size, spring width, U-bolt spacing, and plate hole layout.
• For guide hardware use, confirm the guide style, bolt size, hole spacing, and mounting location.
• Use compatible 1/2" bolts where required by the guide or shackle-related application.
• Use compatible U-bolts and nuts where required by the axle-to-spring application.
• Inspect the trailer axle, leaf spring, U-bolts, guide brackets, side guides, nuts, bolts, and related hardware before reassembly.
• Replace badly rusted, bent, cracked, or damaged mounting plates before towing.
• Do not assume mounting plates are interchangeable by appearance alone.
• Tighten hardware to the proper specification for the trailer application.
• Recheck hardware after service and after initial towing.

Fitment Guidance

This is not a universal trailer mounting plate.

• Confirm the trailer is a compatible EZ Loader galvanized trailer application.
• Confirm the part number is 250-031133.
• Confirm whether the plate is used for axle, spring, guide, or shackle-related hardware on your trailer.
• Confirm 1/2" bolt compatibility where the plate is used in guide or shackle-related applications.
• Confirm U-bolt and nut requirements where the plate is used for axle-to-spring mounting.
• Compare the old plate and mounting location before ordering.
• Use photos, measurements, trailer VIN, and existing part details when checking fitment.

Real-World Insight

Small mounting plates can be easy to overlook, but they often carry important clamping or guide-mounting load. If the plate is bent, cracked, badly corroded, or mismatched to the bolts, U-bolts, axle, spring, or guide hardware, the assembly may not clamp or align correctly.

When servicing springs, axles, side PVC guides, side bunk guides, or frame-mounted suspension hardware, inspect the mounting plate and related fasteners carefully before reusing old parts.
