Drop Arm for the Gemmer recirculating-ball steering box, forming the output lever of the steering linkage.

The drop arm mounts on the splined sector shaft at the base of the steering box and converts its rotation into the fore-and-aft movement of the drag link, which in turn drives the track rod and the road wheels. It uses the 6-bolt fixing pattern and is suitable for both manual (non-power) and power-assisted steering boxes. For left-hand-drive applications.

Frequently asked questions

What does the RTC6399 drop arm do on a Land Rover Defender?

The RTC6399 drop arm is the output lever of the Defender's Gemmer recirculating-ball steering box. It mounts on the splined sector shaft and converts the box's rotation into the fore-and-aft movement of the drag link, which steers the road wheels. Fits Defender 1987-2006 left-hand-drive.

Does this drop arm fit both manual and power steering boxes?

Yes, the RTC6399 drop arm suits both non-power (manual) and power-assisted Gemmer steering boxes on the Defender. It uses the 6-bolt fixing pattern at the base of the steering box. Check yours has the matching 6-bolt sector shaft flange before ordering.

Is this the left-hand-drive or right-hand-drive drop arm?

This is the left-hand-drive (LHD) RTC6399 drop arm. The drop arm is handed to the steering side, so an LHD arm won't position the drag link correctly on a right-hand-drive Defender. Confirm your vehicle is LHD before fitting.

What are the signs a Defender steering drop arm needs replacing?

A worn drop arm typically shows as play or vagueness in the Defender's steering, often from a worn taper where the drag link ball joint seats. Knocking over bumps can also point to wear. Left unchecked, steering slack usually worsens, so replacement restores a tight linkage.

How do I confirm the RTC6399 fits my Defender?

The RTC6399 fits the left-hand-drive Land Rover Defender from 1987 to 2006 with the Gemmer recirculating-ball steering box and 6-bolt drop-arm fixing. Confirm your steering box type and LHD layout, and use your VIN to verify the variant before ordering.
