Shipping was so efficient arrived days before estimated. Order was placed and within an hour was shipped!!!



by:

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.



by:

Install was easy. Raised our Thor Gemini up as product said it would. Great job etrailer!



by:

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.



by:

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.



by:

Works great on my 2016 town and country for hauling my pop up camper.



by:

Fast delivery. Disappointed with the instructions. Sense the item was ordered vehicle specific. The instructions said tighten bolts to manufactures specifications.



by:

Easy install & fast shipping! Works gre at!



by:

Works great on my Honda odessey !! Great customer service as always!



by:

Very fast shipping, had product in 2 days! Very easy to install. Hardest part was lifting the RV.



by:

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.



by:

great product, truck does not squat as much when trailer is attached



by:

Have not driven yet, just installed. Added Monroe coil-overs as well, thanks etrailer.



by:

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.



by:

Price was good compared to other sites. Shipped very fast. Installation was very easy.



by:

Put them on and it is exactly what I need to keep truck level when hauling fifth wheel. Easy to install too



by:

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.



by:

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.



by:

BIG difference in handling a load or trailer ... what a great product!!!



by:

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.



by:

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



by:

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.



by:

Holding up good a year after purchase, work great for pulling my camper



by:

Excellent quality, good prices and great shipping ! Thanks

  • Do Timbren Coil Springs For 2022 Toyota RAV4 Have Weight Rating
    Hi Sharon, There is not a weight rating for the Timbren Suspension Enhancement System # T58GR that fit your 2022 Toyota RAV4, they will be effective regardless of the weight on the springs, as they compress based on the amount of weight you have there. The Air Lift 1000 Air Helper Springs for Coil Springs # AL64VJ have a 1,000 lb weight rating, though that means they can help level your RAV4 with up to 1,000 lbs of weight on the springs. Realistically though, there won't be 1,000 lbs...

  • Rear Suspension Enhancement and Trailer Wiring for 2020 RAV4 LE
    Hey James! For a 2020 RAV4 I'm not entirely sure if that is too much or not. Does it feel like your braking is off when you carry everything? Are the headlights tilting up from the rear sag? Are you bottoming out? If any of these things are true then it would be a good idea to add the Timbren SES - Coil Spring Suspension # T58GR for extra support. If you're driving around with the cargo carrier and a fully loaded vehicle every single day then it is probably a good idea regardless. Front...

  • What Will Work with My Toyota Sienna Hybrid Front Wheel Drive to Help the Squat in the Rear?
    Hello William, Thanks for writing in, you are correct the Firestone #F4155 is not a good fit for the 2021 to 2024 Sienna Hybrid. The hybrid models have some key differences in the rear suspension area due to battery placement and tighter coil spring spacing. Because of that, air bag kits like the 4155 do not have confirmed fitment, which can lead to interference or installation issues and the possibility of still dealing with rear sag after spending the money. A much better and proven...

  • Rear Suspension Enhancement Recommendation for 2023 Toyota Sienna Woodland AWD
    Hey Rick, I have a solution for you but the # CSS-1168R are not listed as a fit for the all wheel drive versions of the 2023 Toyota Sienna. That said we have heard from customers with the AWD versions and it did work well so it should work just fine. Instead we have the Timbren kit part # T58GR which does though and is very similar so it would be what you'd want. Are you towing a trailer?

  • Rear Suspension Enhancement Recommendation for 2019 Toyota Sienna
    Hey Jesse, yes the Timbren rear suspension kit part # T58GR will be exactly what you are looking for to provide more suspension support for your 2019 Toyota Sienna. This will give the rear suspension more support so that when you hit a bump the suspension won't want to bottom out. How much does the chair weigh you think?

  • Trailer Hitch and Suspension Enhancement for 2026 Toyota Sienna With VelociRAX Vertical Bike Rack
    Hey Ben! The Curt does have that restriction on the vertical bike racks so I recommend the TowSmart Trailer Hitch # TS82VR. This has a higher tongue weight capacity and will allow you to carry the VelociRAX. It would be a good idea to add the etrailer Anti-Rattle Hitch Collar # e38FV as well to help cut down on any movement from the rack. Also yes, the Timbren Suspension Enhancement System # T58GR will help with hauling a 6-bike bike rack. Even with lighter bikes that is a lot of tongue...

  • Can 2026 Toyota RAV4 Woodland With Tow Package Use Weight Distribution Hitch
    Hey Tom, congratulations on the new vehicle and camper! This can get pretty confusing so I'll try to clear things up for you here. What you're hearing about a unibody is typically correct. Most of the time you do not want to use a weight distribution hitch, but it is not an absolute. The bigger issue here is that factory hitch. It is not rated for a WDH so we can go ahead and rule that out as an option. That 2,675 lbs I believe is the dry weight for your A214, so you're going to be even...

  • Will Coil SumoSprings Fit 2025 Toyota Sienna AWD
    Hi Thomas; the Coil SumoSprings are pretty universal so they may fit. They're only listed for 2WD because SuperSprings never tested them on AWD models. The fact that the Timbren is listed as a fit for both does imply they will likely work, but I would still measure to be sure. It looks like you decided to go ahead and get the TImbren SES # T58GR instead. These are confirmed to fit AWD models so no measuring will be required. Are you towing with your Sienna or just carrying a lot of...

  • What Would Cause Trailer Sway with Toyota RAV4
    Hey Jose, is the trailer sitting level? Is there possibly not enough tongue weight on the trailer relative to the total weight of it? If the tongue weight isn't 10-15 percent of total trailer weight you will get sway. You will also get sway if the nose of the trailer is too high as well. Suspension enhancement would not reduce sway so I would not recommend that.

  • Suspension Enhancement for 2026 Toyota Sienna Woodland AWD
    Hey Steve! We have never officially confirmed the Coil SumoSprings will fit the AWD model. They probably do, I just can't say for sure. What I would do is get the Timbren SES # T58GR instead. These are confirmed to fit and will have the same level of performance. They also have the same satisfaction guarantee and lifetime warranty, and at least for right now you'll save a little money. What kind of trailer are you towing?

  • Suspension Enhancement Recommendation for 2019 Toyota RAV4
    Hey HPA, I would go with the Air Lift kit part # AL64VJ that fits your 2019 Toyota RAV4 based on what you described and your needs. This gives you adjustable support that you can tailor as needed so that you get the exact amount of support you need when towing or carrying your cargo carrier.

  • Is the Foot Pedal for the Dometic 300 Toilet a Serviceable Part
    Hey Rafael, I checked with Dometic and unfortunately the foot pedal for the Dometic 300 Weekender RV Toilet # DOM64FR is not a serviceable part so It's not going to be available for replacement. You'd instead need to order a whole new toilet if your foot pedal is damaged.
