both the SportLink 1 and the SportLink 2 have been road tested over thousands of miles towing in excess of 1200 to 1400 lbs with no problem. Do to the unique patented design, that incorporates structural spports that insert into the frame sockets and also utilize the 8 bumper mount bolts, there is no stronger system available. We now recommend a maximum of 150lbs tongue weight ,this is more a concern to over-taxing the vehicles suspension not concerns of damage to the SportLink or TowLink attachment.
