Frequently asked questions

What is the RKC5098 mainshaft 5th gear and what does it do?
The RKC5098 is the fifth gear that mounts on the mainshaft of the LT77 and LT77S five-speed manual gearbox. It meshes with the matching layshaft gear to provide the fifth (overdrive) ratio, and it's fitted to the Land Rover Defender and Range Rover Classic running the LT77 transmission.
Which LT77 gearbox suffixes does this 5th gear fit?
This 5th gear fits LT77 and LT77S gearboxes up to and including suffix 50A and suffix F. Check the suffix stamped on the gearbox casing before ordering, because units from suffix G onwards use a revised specification. Matching the suffix stops you fitting a gear that won't mesh correctly.
Why does 5th gear fail on the LT77 gearbox?
Fifth gear on the LT77 typically fails through worn teeth, a whine in fifth, or the box jumping out of fifth under load. It usually wears because fifth carries sustained high-speed running. Replacing the worn mainshaft 5th gear restores a quiet, positive top ratio.
How do I confirm this 5th gear fits my vehicle?
Confirm fitment by gearbox type and VIN. On the Range Rover Classic this gear applies up to VIN HA610293, and on the Defender it covers the LT77-equipped years. Since the specification changed with the gearbox suffix, checking the casing suffix is the reliable final check.
