Shipping was so efficient arrived days before estimated. Order was placed and within an hour was shipped!!!
I HAD THESE INSTALLED ON MY VAN OVER A YEAR AGO, I JUST CHECKED THEM OUT AND THEY ARE STILL IN GREAT CONDITION. THE FACTORY ONES I HAD PREVIOUSLY WERE COMPLETLY WORN DOWN. THE TIMBREN LOOK THE SAME AS WHEN THEY WERE INSTALLED.
Install was easy. Raised our Thor Gemini up as product said it would. Great job etrailer!
had this product before. left it on my old truck when I traded. Now I have to replace it, really like what it does for my towing a travel trailer. just have to find time to put it on. speedy delivery arrived undamaged, which is nice.
They definitely reduced sway and lean when driving. But also seems like you really feel every bump and increase road noise?
I assume since vibration from axle can now travel directly to frame?
Might need to upgrade shocks?
Might soften liitle over time?
Might need to get softer onesv
Only have gone 80 miles with them so far.
Will give it another few hundred miles and see what feel then.
Overall pretty happy So far.
2017 Thor Gemini TX
Strainer/basket is holding up well after one year of use in our RV, no issues.
Works great on my 2016 town and country for hauling my pop up camper.
Fast delivery. Disappointed with the instructions. Sense the item was ordered vehicle specific. The instructions said tighten bolts to manufactures specifications.
Easy install & fast shipping! Works gre at!
Works great on my Honda odessey !! Great customer service as always!
Very fast shipping, had product in 2 days! Very easy to install. Hardest part was lifting the RV.
The product first arrived in a damaged box with one of the washers missing, but ETrailer did resupply that. The hardest part was finding a shop able (needs the right tools to depress coil springs) and willing (a potential liability issue messing with suspension) to replace it for a reasonable cost. Eventually a local tire shop agreed to. This was for a 2014 Honda Odyssey, especially for pulling a pop-up. Took two camping trips last summer, one before and one after installation, and I have been pleased with the added stiffness in the rear suspension. It made about 1 to 1.5 inch of difference in resting position when fully loaded and towing and has helped smooth out bumps and humps in the road - both when towing and not.
great product, truck does not squat as much when trailer is attached
Have not driven yet, just installed. Added Monroe coil-overs as well, thanks etrailer.
Delivery was fast, instal was quick & easy. Later today I will see how they work when I hook up to the 5th wheel. By all indications right now I believe they exceed my expectations.
Price was good compared to other sites. Shipped very fast. Installation was very easy.
Put them on and it is exactly what I need to keep truck level when hauling fifth wheel. Easy to install too
I would recommend this product to anyone. I pull trailers with a 1/2 ton truck and will never have another one without this product on it.
I put this product on my Trooper. The install was easy is you take the back wheels off. I towed this weekend and I did not bottom out. If they hold up over time, this is a great product.
BIG difference in handling a load or trailer ... what a great product!!!
Did my due diligence researching this product, including other customer reviews.
Can't wait to install them, but the Winnebago has been put to sleep for the season. I'll submit a performance report in the spring.
15 mins to install and what a difference…. Went from a few inches of sag in the rear to only an inch and over 1000lbs tongue weight didn’t know the trailer was attached to the truck
I had trouble installing these. Turns out they Don't match the factory stops. I trimmed off some rubber on the press fit end and they went all the way in with the truck weight help. I hope they stay in.
Holding up good a year after purchase, work great for pulling my camper
Excellent quality, good prices and great shipping ! Thanks
