Gearing questions 4.10 rear? How many spline axle 30, 32, 35

Hey guys,

I’ve been doing my research. Our Defenders Rear differential shares the same part number with the 2020 Range Rover Sport l494...

Do our cars come with 4.10 gears? I found an arb e locker for 4.10 gears, and I found a spec sheet for our2020 defenders confirming the same, but how many splines do we have? 30, 32, 35, spline axle? The reason why is ARB sells an e-locker for 4.10 gears in 30, 32, and 35 spline axle configurations. Please see attached.

I think I’ve got my e-locker worked out, I just need to confirm these last specs...

Thanks, Mark

I’ve also been talking to an aftermarket company. I can’t name them since they aren’t publicly announcing this option yet. All of our Defenders come with Terrain Response 2. They found it disabled in the software Pathfinder which is the dealer software. They are working on enabling it under their R&D program!

Sorry can’t help with the e locker query but that TR2 software program I’ll be very interested in getting this installed on mine as it wasn’t an option on the First Edition spec D90

Thank you. I have a P400 so I need to find the ARB e locker with the 3.73 gear. I wish I knew the spline count. 2022 Defender Trek Competition 110 collectors edition!
