Description

Q: Will these fit a fifth wheel slide-out?A: Yes. Adjustable 20"-40" height fits most fifth wheel slide-outs, travel trailers, and Class A motorhomes. The U-shaped top accommodates standard slide-out frame widths.Q: Will the jacks sink into soft ground or grass?A: The 5" diameter circular base distributes weight to resist sinking on grass, dirt, gravel, and sand. For very soft surfaces, we recommend placing a wooden leveling block underneath.Q: Are these silent? My current stabilizers make noise.A: Yes. The U-shaped top has an anti-vibration rubber mat that eliminates the metal-on-metal contact noise. No squeaking, no clanking — even when the slide-out moves slightly in wind.Q: How long does it take to set up one jack?A: Under 60 seconds. The folding handle quickly raises the bracket to meet the slide-out rail. No assembly required out of the box.Q: Will this support the weight of a heavy slide-out?A: Each jack supports up to 5,000 lbs. A pair supports up to 10,000 lbs — enough for the largest residential-style slide-outs in Class A motorhomes.Q: Can I use these on a Class A motorhome?A: Yes. The 20"-40" height range and 5,000 lbs capacity per jack handle Class A slide-outs.Q: Do they rust if left outdoors?A: The zinc powder-coating finish is rust-resistant for outdoor use. We recommend storing indoors when not in use for longest lifespan.Q: Can I use one jack to support an RV bumper-mounted carrier?A: Yes. Many customers use a single jack to stabilize rear bumper-mounted bike racks or cargo carriers. The 5,000 lbs capacity is more than sufficient.Q: What's the lowest height?A: 20” at the lowest setting. If your slide-out is lower than 20", you'll need to place leveling blocks underneath the base.Q: Comes as a pair or single?A: Pack of 2. Most slide-outs need 2 jacks for proper support.

  • Very solid
Size: 20-37“
Easy to use and adjust. These work great and really help to reduce shake. Remember that you do not want to lift your slides at all so you do not compromise the seal on your slide. Most slide seals depend on the weight of the slide to seal properly.

  • Good and solid support for your slides.
Size: 20-37“
Very solid, provides great support for even heavy slides, like mine. Easy to use. Size just right for my 5th wheel. Excellent value, lightweight but very sturdy and built well.

  • Works well and easy to use
Size: 20-37“
They might be cheap, but they do work well. I put a paver stone down and then put these right up into place. I have them where they were touching and then just went about a half to full turn tighter just for added support on my slide without putting any extra pressure on it. I'd recommend them for just the peace of mind ... show more

  • Good product

Easy to use seems to be sturdy something that all RVs should put under their slide outs

  • Great stabilizers!
Size: 20-37“
I’m using these stabilizers on the rear of my rv instead of on the slideouts of my Rv. They’re doing a great job!

  • This is the stabilizers you’ve been looking for!
Size: 20-37“
Very competitive price, easy to use, great quality and had them in place on my fifth wheel slide-outs in minutes. The rubber pad on the top is a must!

  • Work great.
Size: 20-37“
Love how such a simple item can make such a big difference. Put it under my slide-out in kitchen and the floor is sturdy now. Doesn't move like it did before. Wish I would have bought them years ago when I first purchased my camper.
