FRAME RAIL TIE DOWN BRACKETS help control up and down/vertical movement of your vehicle in your hauler/trailer to reduce wear on your suspension system, including springs and shocks.
3/8″ Raw Steel (to facilitate welding), 90 degree angle to fit frame rail. Must be welded to rail, see photos for recommended weld placements. NOTE: When securing your vehicle to the trailer, compress the vehicle ONE INCH MINIMUM for best results.
Combined with our regular Tie Down Brackets, your vehicle is secured against side to side AND up and down movement within your trailer/hauler to protect your vehicle!
