thanks for the detail, yep it makes sense that the traction control would detect the wheels are turning at the same time with the axle locked and so would not interfere. I didn't realise alloys were rated much less. I guess the spring rate for HD would probably make for a very choppy ride in a station wagon unless they were well loaded (which is v. unlikely)....

thanks guys. Yep the HD option is available for all the 110 body types for 2007....

Hi (first post for me) I'm just going through the options on a 2007 Defender (110) and I came across the following. "Heavy Duty Suspension 3,500kg, includes heavy duty wheels, G90 tyres, heavy duty jack, heavy duty axles & heavy duty clutch = £1740" This option is available to all 110 body types yet the 130's have it as standard....I've never heard of it before, questions that spring to mind are: #Heavy duty clutch (any idea what this is? Is it a more hard wearing friction plate?) #Heavy duty axles (again, no idea what this means, I assume its not a Salisbury axle?) I intend keeping this one for a long time so I'm considering it. I also have a couple more questions > can you turn a corner on a hard road with diff lock engaged? I've can't remember ever trying this, and I'm not in a position to test one...I believe the Defender has central diff-lock, and when it's engaged I think it supplies the same drive to front and back axles together, but individual wheels on the same axle can still spin if they loose grip? > can you switch the traction control off in a 2007 Defender? I understand its supposed to help a bit if one wheel is spinning more than the other, but I wonder if it would interfere with an aftermarket axle diff-lock.... Many thanks!!
