Extreme Trailer Lowering Guide

How to lower your Extreme trailer

DISCLAIMER: TheMalibuCrew.com and the author of this article offer these instructions simply as a guide and hereby relinquish all liability and responsibility for the results of said instructions. By following any instructions set forth in this article, you agree that you are doing so at your own risk, and accept the consequences of your own actions. Again, we will not be held responsible should any undesired outcome result from following the instructions below.

My trailer is a 2005 completely stock tandem axle extreme trailer that carries my 2005 VLX.  This article depicts the measurements that I obtained from repositioning the torsion axle spindles; yours may be different.

One spline will equal between 1/2" to 5/8”.  I have not towed the trailer yet to see if it will settle, so it may end up being a little lower yet.

I originally had 3” of clearance between my tire tread and fender.  After this mod, I now have 1.5” clearance which I still I believe to be plenty of room for wheel travel.  See pics.

  • Position the trailer on level ground.
  • Chock the left side trailer wheels for safety.
  • Position a floor jack on a trailer frame rail so that the jack will lift both right side wheels off the ground at the same time. (I positioned the jack under the forward axle beam.)
  • Break loose all the lug nuts on both right side wheels.
  • Jack up the right side of the trailer.
  • Place jack stands under the trailer. DO NOT rely on just the floor jack to hold up the trailer, the seals may blow out and drop the trailer to the ground!
  • Remove all of the lug nuts and pull the wheel assemblies off of the right axles.
  • Completely loosen and remove the 15/16” nut & bolt that secure the spindle to axle shaft.
  • Mark the current position of the spindle and axle shaft.
  • Use a pry bar between the spindle and axle end cap to get the spindle loose from the splined axle shaft.
  • Wiggle the shaft forward to aft until it is off the splined axle shaft.
  • Now, reposition the spindle on the axle shaft at the new desired location to lower your trailer (see my measurements to determine where you want to reposition the spindles).
  • Slide the spindle on the axle shaft into its new location.
  • Install the 15/16” nut & bolt (I do not know what the proper torque is; it is tight!).
  • Install the wheel assembly.
  • Now do the other right wheel (repeat steps 8-15)
  • Repeat steps on the left side
