Overview

The Terrafirma TF532 is a pair of Johnny Jointed rear radius arms designed for significant articulation in custom suspension systems. These arms utilize the American Johnny joint, offering 30 degrees of articulation, which is more than conventional rose joints. The TF532 arms are constructed from heavy-duty material with a 1.5-inch diameter and 5/16-inch wall thickness, ensuring strength and durability.
Show original supplier description
The Terrafirma TF532 represents a premium upgrade for off-road suspension systems, featuring the highly regarded American Johnny joint. This joint is renowned for providing exceptional articulation, reaching up to 30 degrees, which surpasses that of standard rose joints. The heavy-duty construction of these rear radius arms, built with 1.5-inch diameter tubing and a 5/16-inch wall thickness, ensures they can withstand demanding off-road conditions. Designed to allow for massive, unrestricted, and stress-free rear axle movement, the TF532 arms are ideal for custom suspension builds and enhancing the capability of vehicles like the Defender, Discovery 1, and Range Rover Classic. These arms are greaseable, offering better sealing and superior resistance to wear compared to conventional joints, contributing to a longer service life and consistent performance. Each arm is supplied with a weld-in bung designed to fit 35mm ID tubing and includes a locking nut for secure installation. While the arms themselves are robust, it's important to note that bushes are not included with this kit, and will need to be sourced separately to complete the installation.
