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 at 1000kg was considered a lightweight application.
Couplemate recommends using Australian-made 32mm drop plates cut from virgin steel.
However, the 9" brake setup uses an unbraked tandem trailer 2000kg setup.
The drop plate was not engineered well enough to prevent shock loading when the rig hit a gutter on a roundabout.
Additionally, installing bearing buddies on drum-braked axles is not a good idea. 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 stresses u-bolts and other suspension trailer parts like shackles and bearings.
