Product worked perfectly. I want to commend the sales rep who handled my call for finding this item, because I could not locate it on the Etrailer site. One suggestion to Etrailer. You put the item sticker on the top, where it wears against the turret. I had to very gently scrape it off and then use goo gone to remove the residual glue. If you put your item number sticker on the bottom you would eliminate this inconvenience. I have used Etrailer many times and have ALWAYS been satisfied with the product and service. MANY THANKS 498543

Perfect fit for us. Be sure to read the torque specs on the manual that came with your hitch. It is crucial to lubricate and then torque, loosen and lock tite and re-torque to a less ft lb to keep the plate from warping. Glad they offer this as a separate part aside of the kit. 421470

  • What are Sidewinder Wear Plates Made of and How Long Do they Last
  • I spoke with my contact at Reese who said that the wear plate on Sidewinders is made of a hard plastic/resin material but could not provide the formula for it to me. It is a harder, denser material than lube plates but similar. The plates last a long time and it is unlikely that you will need to replace it. But if you should need to replace it we have # 113983 which is the lower wear disc for Sidewinders with a 4 bolt cap. the top one is # 200959.

  • Replacement Lower Wear Plate, Pivot Bushing, and Upper Wear Plate for 19K Sidewinder
  • To replace the lower wear disc on your 19K Sidewinder pin box, you can use the Reese Replacement Square Lower Wear Disc for Sidewinder # 113983. I spoke with my contact at Reese and 5th Airborne and he confirmed that these are the correct parts for the Sidewinder pin box. The pivot bushing is not available as a replacement part. Since you'll have the pin dismantled to replace these parts, if you'd also like to replace the upper wear disc, you can use the Reese Replacement Top Wear...

  • Availability of Replacement Wear Disc for Sidewinder Fifth Wheel Pin Box
  • Your Sidewinder is rated for 16,000 lbs, the fact that it is overloaded could possibly explain the noises you are hearing during turns. Since your Sidewinder has the 3 bolt cap, the bolts need to be tightened to 80 foot pounds. Unfortunately, we do not accept trades. We offer replacement wear discs, the upper is part # 200959, the lower is part # 113983. I would recommend upgrading to the the 19K Sidewinder or the 19K Air Ride System, as your current set-up is not safe.

  • Sidewinder Pin Box Maintenance for a 2007, 32 Foot Everest 5th Wheel Trailer
  • To address the issue of the angled arm we will need to check a few things. First of all, your pin weight cannot exceed 3,200 pounds for the 16,000 pound sidewinder so, you will need to check the pin weight of your trailer to be sure you have not overloaded the Sidewinder. If your pin weight is too heavy, you will need to reposition the load in the trailer to lighten the pin weight or upgrade the sidewinder to accommodate the load. If you have an older Sidewinder installed on the trailer...

  • Measurements for Replacement Wear Plate # 113983 for Sidewinders
  • The easiest way to figure out which where plate you will need for your Sidewinder is to look at the cap on the end of the arm that goes up into the turret. If it has 4 bolts then # 113983 is the correct lower wear plate. I included a picture showing the dimensions. The top wear disc is # 200959.

  • Troubleshooting Play in a Sidewinder Pinbox
  • There could be a couple reasons your Sidewinder has some play in it. First you would want to check the turret bolts on the top of the turret. See picture to see where these bolts are. If you have a 4 bolt setup they should all be tightened to 45 ft lbs of torque, if it is a 3 bolt setup they will all need to be torqued to 85 ft lbs. Another possibility is that the wear bushing inside of the turret has worn out. The lower wear disc could also be worn, the replacement would be part...
