    With camping season coming up, I decided to install a set of Timbren's in the rear to combat some of the squat when towing our camper. These basically replace the rear bump stops with something much beefier. It was pretty easy and required minimal tools.

    Here you can see the factory bump stop clamped onto the leaf spring. This is what gets replaced.

    This is from underneath the U shaped bolts. I soaked the nuts down with some PB Blaster the day before to help break down some of the rust. The nuts are 21mm. You can pretty much just loosen them without taking them completely off and remove and replace the bump stops, but I took the bolts completely off and cleaned the threads with my bench grinder.

    Factory vs. Timbren SES
    20190415_135815.jpg

    Here you see once the nuts and bottom plate removed, the U bolts simply slide up to be cleaned if you wish.

    Timbren's
    20190415_141223.jpg

    Reverse the process to install them and torque the nuts to spec. As you can see, there's maybe an inch gap in between the Timbren's and the frame. When unloaded, the ride is unaffected. But once a load is placed in the bed or you tow, the frame sits on the Timbren's and the squat is greatly reduced. My first ride with them towing is coming up soon, so I will update with the results.

    I was looking at these earlier today, comparing with sumo springs. I’m curious to see how you like them after a little bit.

    Yeah, I was going back and forth between those as well. I went with the Timbren's just based on peoples experience with them. They seem a little more heavy duty compared to the sumo springs. We'll see...

    I worry about how much different they would feel off road, if they would make for a harsh ride

    Heads up, you can bolt on a super bump in place of the timbren if you’d like to gain some travel back. Then bolt the timbren back in when you need, for load. @JoshuaA did this.

    Something that should go along with the sale of items like these should be a replacement set of U-bolts. They may say it in the fine print, they may not but those bolts are a ONE TIME usage item. Once they are installed and torqued they should not be removed and than reused. Just a little safety issue you or anybody else looking to add something that is attached like the Timbrens are.
    On the other hand, how do you like them? Have you put them to work yet?

    I have 1.5” shackles so I use 1.5” spacers with my Timbrens. When not towing, I remove the spacers. The footing stays so it’s just a matter of unbolting and bolting. The increased space means it never hits in day-to-day driving. However, those who aren’t lifted in the back may find hitting the Timbrens a little jarring, which you’d only notice over speed bumps and potholes if that.

    9E484BDD-5098-4B83-9502-35F9BD36DE8A.jpg

    For people that tow all year and with varying weights, I’d go airbags.

    And for people with lighter tongue weights, I’d go Sumos which are more forgiving.

    Timbrens are pretty solid. You’d want a heavy TW riding on them all the time to prevent shudder. Bouncing up and down off of them would not be fun.

    I can’t remember who does that but I went the spacer route instead as I’m up 1.5” higher in the back. If I was stock height, I would definitely switch them out with shorter Superbumps when not towing, the solution to avoid smacking Timbrens.

    Ive had the front and rear timbrens for four seasons now along with the trd rear sway bar. If you want your truck level when you tow i highly recommend them. 6k lb capacity which gets the job done.

    So I picked up the camper from storage and brought it home to de-winterize it. It was about a 20 mile drive and had a chance to test the timbren's. I'm happy to say it drove GREAT. They kept the truck level and it felt stable the whole time. If anyone's on the fence on whether or not to get these, I highly recommend them. 20190427_095924.jpg

    Thanks for the info. I’m picking up my new 26’ trailer next week and am considering air bags or Timbrens. This info will help. I had airbags in a previous Tacoma but they didn’t hold up in -20 degree Minnesota winters.

    Great post! I went with the black sumo springs last year.
    Prior to installing my family and I went to the river for a load of river rock.
    I hauled them in the bed and on the way home I had to take it easy due to sway.
    After install we went back a few weeks later, the difference was night and day.
    The truck felt well planted.

    I love mine but like others have said. It can be a little bumpy going done the road. But with my lift kit I never feel them unless I have my camper in tow but you may feel them hit going over speed bumps. But over all I recommend them to anyone hauling an decent size load. My camper hooked up with them on. Screenshot_20190522-193741_Gallery.jpg

    She's been really good to me!
    I've done the ECGS bushing upgrade and brake pads.
    I need to replace the passenger side valve cover gasket due to an oily plug.

    Yes besides the usual oil and grease.
    I run the toytec shackles at 1.5 so the sumos are about an inch below the contact point.

    I have seen some do plugs at 100k I'm thinking that also and maybe a trans flush because I do tow a camper with it.

    I'm due for tires probably after summer.
    I really like the Cooper at3 xlt and the Falken wildpeak.
    The price says Falken but the weight says Cooper???

    I like my timbrens as well. Had them on my 2007, moved them to my 2018. Definitely make my ride more stable. I pull a gooseneck stock trailer (draft horses) that can hit 10,000 lbs and a 28 foot bumper pull triaxle cargo trailer (8.5 wide, 8.5 high, 28 feet on floor) loaded with show equipment. Loaded it runs about 9,000 lbs. Use weight distributing hitch of course.
