Description

Overview

Radius rod adjustable screw 420mm changes rod length in adjustable radius rod and torque rod assemblies. That lets mechanics set axle position and keep the suspension tracking correctly. The 420mm screw length and 38mm (1.5″) thread size suit common trailer suspension layouts across TMC, Fuwa, YTE, York, R.O.R and Sinclair applications. Use it where the existing screw matches those dimensions. When the original thread is seized, damaged or worn, this replacement helps restore clean adjustment through the rod assembly.

Features

• 420mm adjustable screw for radius rod and torque rod assemblies
• 38mm (1.5″) thread size for matching suspension rod ends
• Suits selected TMC, Fuwa, YTE, York, R.O.R and Sinclair setups
• Match thread size, screw length and mating ends before ordering

Compliance and Safety

Support the trailer before loosening any suspension rod hardware. Measure the existing rod position before disassembly so alignment stays close during refit. Clean the threads and inspect the mating ends. A new screw will not correct damaged rod ends or worn lock points. After installation, set the trailer at ride height and tighten all related hardware to the suspension maker’s procedure.
