32mm Axle Drop Plates

32mm Axle Drop Plates to suit 45mm to 50mm steel axle beams

32mm Axle Drop Plates suit 3" and 4" Axle Drops. Plates to fit a variety of 45mm and 50mm axles and stubs. Suitable for horse floats and boat trailers.

Question: What size drop plates are available to lower my caravan

Answer: Drop plates lower the height of the axle from the ground to suit various size stub axles and beams.

• 3" x 45mm Square Beam to 45mm round Stub.
• 4" x 45mm Square Beam to 45mm round Stub
• 4" x 50mm Square Beam to 45mm round Stub
• 4-inch x 50mm Square Beam to 50mm round Stub

The thickness of the drop plates is critically essential. Plates installed on axle assemblies less than 32mm in width can result in disastrous consequences.

The IRS in the photo has been built with a 25mm drop plate. The 25mm plate was used because the 9" mechanical assembly rated to 1000kg was considered alight weight application.

However, the 9" brake setup was used with an unbraked tandem trailer 2000kg setup. The drop plate was not engineered well enough, in this case, to prevent the shock loading when the rig hit a gutter on a roundabout.

Additionally, it is not a good idea to install bearing buddies on drum braked axles. Excess grease contaminates brake shoes rendering them ineffective during a braking event.

Finally, all drop plate assemblies built by Couplemate are 32mm wide. Some narrower plates can twist under extreme loads and cornering. This action places stress on u-bolts and other suspension trailer parts like shackles and bearings.
