Kzrv is recalling 19 2017-2018 Sportsmen Sportster trailers because the slide out support arm sits too close to the tires.

What's wrong?
The slide-out support arm on a 2017-2018 Kzrv Sportsmen Sportster trailer helps carry and steady the room extension when that slide is moving or locked in place. It sits near the trailer tire area, so the design has to leave enough space for the tire to move up and down as the axle travels over bumps.
On affected trailers, that clearance is too tight. While the trailer is being towed, normal axle travel lets the tire contact the slide support arm, including the adjustment bolt. That contact rubs against the tire instead of leaving the tire free to rotate without interference. Over time, the rubbing damages the tire and raises the risk of tire failure while towing.
Owners should look for visible tire wear where the tire has touched the slide support arm adjustment bolt. That wear is the warning sign before the tire fails.

What should I do?
- Check your VIN to confirm your 2017-2018 Kzrv Sportsmen Sportster is included in this recall.
- Contact a franchised Kzrv dealer to ask whether the free slide-room support-arm clearance modification is open for your VIN.
- Reference recall number 17V645 when you call, and have the trailer VIN ready.

- Bring the recall notice if Kzrv mailed one, or ask the dealer to look up the recall by VIN.
What happens at the repair
At the dealer, a Kzrv technician modifies the slide room support arm so it has proper clearance from the trailer tires. The work is meant to stop axle travel during towing from letting the tire contact the support arm. Kzrv listed the recall start date as November 17, 2017, but the remedy status is not marked available. The final dealer repair will be free once available, with parts and labor covered under the recall.
