Monroe Trailer Retrofit Kit
MODIFIES YOUR TRAILER SUSPENSION TO ACCOMODATE SHOCKS

For trailers that have either a leaf spring suspension or a torsion axle suspension, Monroe manufactures the Retrofit Kit.

Adding Monroe RV shocks reduces the bounce and wander of your trailer for improved towing capacity. Monroe RV shocks also reduce the surge caused by trailer motion feedback to the tow vehicle, for a smoother, more comfortable ride. Recommended for use with Monroe RV shock absorbers for a softer, more controlled ride.

Easily installed without welding or special tools, this do-it-yourself kit enables modification of your trailer suspension to accomodate Monroe RV shock absorbers.

Kit Selection: For installation of a retrofit on your light duty trailer, you need to determine what type of frame and suspension you have on your specific trailer. The frame types shown will reflect mounting the shock on the inboard side. If ample clearance (about 4 inches) exists between the frame and the tire, outboard installation is acceptable.

Note that one kit is required for each axle, therefore tandem axle requires two kits.

Easy Installation:

  1. Determine the frame type:

  2. Determine the diameter of your axle (leaf springs.) Determine specific GVW rating of your trailer suspension (torsion axle)
  3. Based on the axle diameter/GVW rating from step 2, locate the correct retrofit kit from the corresponding chart below
  4. Determine the location of the upper mounting. Measure the distance between the upper and lower mountings. Based on the centerline dimension at the vehicle static height. Dimension should be taken with trailer on level surface.
  5. Using the measurement from step 4, select the appropriate Magnum RV shock absorber from the third chart below.
  6. You can download the instructions for the Monroe kits. They are in the standard Adobe PDF format. CLICK HERE for page 1 (860KB). CLICK HERE for page 2 (760KB).

Due to the variances of different modifications to a vehicle or trailer, it is your responsability to measure that the shocks and kits you purchase are dimensionally correct.

Due to the variances of different modifications to a vehicle or trailer, it is your responsability to confirm that the shocks and kits you purchase are dimensionally correct. Determine the shock absorber required based on the centerline to centerline dimension at the vehicle static height taken on a level surface. (see diagram at bottom). If you are not sure what shocks to use, you can purchase the kit first, install it, do the measurement, and then purchase the shocks.
