FAQ

• Do you have these in stock?

  • yes, we stock many kits all the time and we ship every day worldwide.

• Can you lift your trailer 3" will that damage the suspension?

  • You Can lift your trailer 3", however we do recommend installing a cross member on the back hangers to prevent side to side twisting of the rear hangers, this can lead to cracks in the welds that hold the hangers to the frame. (cross member linked here)

• How High do I need to lift my Trailer?

  • Hook up your trailer and set your towing height or 5th wheel pin height that you wish to tow your trailer at.

  • Park your truck and trailer on flat ground to measure

  • Measure the front of you trailer and the back of your trailer at the straightest most even and level part you can find. (frame, trim, seam)

  • If you are out 6" then you need a 3" block

  • If you are out 4" then you need a 2" block

  • if you are out 2" then you need a 1" block

  • Whatever measurement you raise the suspension it will (almost) double at the rear bumper
