I have 30 Inch on mine. It's a 2020 defender limited they put them on at the dealer when I bought it and haven't had any issues so far. But they didn't say anything when they put them on that I needed to adjust anything.
I have an EPI clutch kit see the builds section and Dalton has one out for the Defender Cab XT HD10.
Whether springs or springs and helix the clutch(s) primary and secondary need to be taken apart, there is no adjustment like on a mountain sled clutch.
