Description

Overview

Lelox STCP Subplate gives you a solid mounting base when you are fitting a straight chassis tube bracket setup on a heavy vehicle. It sits between the bracket and the chassis rail, so the assembly clamps down more evenly. Because the sub plate helps distribute load, it can reduce local flex and fretting that can happen around bolt points over time. Use it when you want a cleaner, more stable mount for mudguard, spray suppression, or similar chassis-mounted accessories.

Features

• Steel sub plate designed for straight chassis tube bracket assemblies
• Helps spread clamping load across the chassis rail
• Supports a flatter bracket interface, which can improve hardware alignment
• Simple bolt-up style that suits service and replacement work

Specifications and Materials

This product is a steel sub plate intended to suit a straight chassis tube (STCP) mounting arrangement. Use it as the interface plate under a compatible chassis tube bracket so the bracket can clamp evenly to the rail. See the manufacturer installation guide for chassis pipe brackets at manufacturer installation guide for chassis pipe brackets
Part number: CA5579.

Compatibility and Fitment

Lelox STCP Subplate is designed to suit straight chassis tube bracket mounting, so it is a good match when you are using the STCP style chassis bracket tube system. Before tightening, check that your chassis rail surface is clean and flat, then confirm the hole pattern and fastener length suit your bracket and rail thickness. If you are fitting it to an existing setup, also inspect for elongated holes or cracked paint around the mount because those signs usually point to movement. Tighten hardware evenly, then re-check tension after the first run because clamps can settle.

Compliance and Safety

Use appropriate fasteners and torque practices for heavy vehicle chassis-mounted accessories, and follow the bracket maker’s installation guidance. If your fitment involves drilling or chassis modification, check local requirements and workshop procedures first. In addition, inspect the bracket stack regularly, especially after off-road work or high-vibration service, so you catch loosening early.

Trailer Applications

Lelox STCP Subplate suits many heavy vehicle fit-outs where a straight chassis tube supports mudguards or spray suppression components on trailers and prime movers. It can also suit builds where you want a stronger interface under a chassis tube bracket because the mounting loads repeat with suspension movement and road vibration. For fleet maintenance, keeping a spare sub plate on hand can speed up repairs when a mount needs to be rebuilt.
