ste clark Posted January 19, 2009 Share Posted January 19, 2009 can you legally tow 3.5 tons with a disco???? i was told its not so i bought a 110 to tow the 3.5 ton mini digger when i had it..... Quote Link to comment Share on other sites More sharing options...

ste clark Posted January 19, 2009 Share Posted January 19, 2009 would enquire about h/d rear springs off a 110 then.... someone on here will know spring ratios and part numbers and no doubt will be along soon!! i was told by a number of people who tow plant and large trailers i could not tow that much with the disco so i bought the 110.... more money wasted i suppose!!!!!!!!!!!!!

(With the exception of the Mpi - engined Discovery), all Range Rover Classics, Discoverys & Defenders can tow a max of 3500kgs with overrun brakes. IIRC they are also rated to 5000kg with coupled (air) brakes. You can't fit Defender 110 rear springs on a Disco - they are larger in diameter (7" as opposed to 6"). Have a look here for spring rate info. Matt Quote Link to comment Share on other sites More sharing options...
Pete Attryde Posted January 19, 2009 Share Posted January 19, 2009 110 rear springs won't work without a lot of work, as they are a larger diameter than 90/discovery/rangerover rears. From the Tech archive Spring info. Pete. editted to add :- Matt can type faster than me Quote Link to comment Share on other sites More sharing options...
stevegibbs Posted January 19, 2009 Share Posted January 19, 2009 When towing with your disco doesn’t forget the max weight is everything, load, trailer. tools etc and keep the ball hitch weight to 25-40 kgs. So many people over or under load the hitch. Sorry if i'am talking to the converted but it’s one of my pet hates when i see cars with the bonnet up or the tail down when towing.

ste clark Posted January 19, 2009 Share Posted January 19, 2009 a plethera of information!! i love this forum!! i have also learned people convert salisbury axles to disk brakes and use them on the disco for better weight carrying/towing abilities!! probably not a cheap or easy option but probably better in the long run..

ste clark Posted January 19, 2009 Share Posted January 19, 2009 no real point in changing the axle to salisbury one if you cant use the proper 110 springs though is there?? seeing as the springs are in between the weight to be towed/carried and the axle???
