After 25+ years of off-roading, mud, dirt, grime, sand, rust, road salts, etc., you may be having issues with your factory triple locked Land Cruiser or LX450 engaging the electronic e-lockers. Fortunately these are still available OEM new, without paying $875+ for the Toyota box! We only use OEM Toyota parts for anything and everything where we can, as nobody built a better 80 series than Toyota themselves!
You'll need to check your truck to see what the specific issue is, as replacing this alone might not fix your locking issue.
Please contact us for availability, rarely more than 3-5 days for this to ship out.
Please note that if you do NOT have a triple locked K294 axle code Land Cruiser, you will need much more than this to convert your diffs using factory parts. You would have to hunt down the rest of the parts including all of the axle hardware, the wiring, the switch, etc. We do not have a source for those parts.
