RS16933LH RS16933RH Trailer Ramp Springs, 4-Pack

Make heavy trailer ramps easier to manage with Ruzo & Root Trailer Ramp Assist Springs. Designed for compatible utility trailers, equipment trailers and heavy trailer gates, these torsion springs provide mechanical assistance during both lifting and lowering. The spring tension helps offset the weight of the ramp, reducing the physical effort required while promoting smoother, more controlled operation. This four-spring package includes two RS16933LH left-hand springs and two RS16933RH right-hand springs. Each spring is designed to fit a 1-1/2-inch shaft and is manufactured from heavy-duty alloy spring steel for reliable strength, elastic recovery and repeated use.
