Question:

first off thankyou for all the great help and products I have gotten from you in My current trailer build I bought four SP-111275 7,000lbs springs off you as well as the APT3 spring hanger kit for my car trailer .. its running 2 6000lb axles with ST235/80r16 12ply tires ... the trailer weighs 1672lbs empty and I have a 6000lb Jeep to carry one it .. ok the question ... how much clearance over the tire is recommended when fully loaded to allow for this supension set up to move upward ? I have drive over fenders on the trailer so I would like them to be as low as possible

Expert Reply:

It all depends on how much the suspension travels but I would say unloaded you would want at least an inch from the tops of the tires to the bottom of the fenders. Keep in mind though that over time the springs will flatten out some, as much as half an inch, so keep that in mind years down the road.

You could also add some suspension enhancement, # TTRA1032, rated for 7,000 pounds, which will help with support and ride quality. And it will prolong the life of the suspension. For a tandem axle trailer you would need two kits.
