Dobinsons Coil Spring Rear Suspension Upgrade (C59-819V) Installed on 2024 TRD Off-Road Longbed

[elturco]

Took the truck back out off roading, this time racing the truck fast down the dirt road with plenty of rocks and holes and I love the suspension. 819s with 400 lbs in the back and the peak suspension 2 inch lift. Ride was very smooth and the modified suspension performed really good. Just an update if you are wondering how the springs feel under the expected usage on a dirt road.

This thread is invaluable to understanding how to haul heavy campers/loads. I'm wondering what load range tires (C?, E?) people are using especially over 1000 lbs in the bed. Also, has anybody found a front spring to level without a spacer?

I'm on stock tires. Don't plan to change unless I can find a buyer for my low mileage stockies.
Haven't found any front springs yet. I actually need to look more into my front lift solution.

With my minimal weight I am on "E" tires. I like them.

Finally installed my 817's and cannot believe the improvement! Brought it just a hair above stock height with the unloaded camper on and completely eliminated the bounce I was getting. I either forgot how comfortable the truck was before I got my camper or it's even better than before. Was happy with how easy install was too. I just followed the All Dogs Offroad lift install video on YT and all went smoothly.

Looking good. Love the Lone Peak!!!! It is funny how much further forward it sits over the roof with the five foot bed as opposed to where mine sits on the six foot bed.

There's a thread on Alldogs Off Road springs that's been posted in the past couple of days for front springs. I don't have the link off the top of my head but I'm sure you can find it if you search the forum. If nothing else, here's the Youtube video where they go into the install (I have yet to watch it so hopefully it's informative...). I was thinking I would replace the front springs after installing my bumper and winch but after actually doing the install I think I'm happy enough with the spacer kit. I don't need the springs at this point.

I'm running the KO3 with a C rating and I'm perfectly happy with them. I personally don't see any reason to run an E rated tire, even with all the weight I'm carrying.

Thanks! I'll check it out. Haven't had time, but still need to lift the front. I may end up with spacers also though.

It really depends. I do light "off roading" and on occasion had the fortune to run areas with sharp rocks, here in the so cal deserts. I can tell you from experience that a E rated tire will survive damage better than a C rated tire. I have seen big chunks of tire shaved off by the rocks and the only reason they survived was the 10-Ply on the E tire. I really love my KO3s E rated, they also give me a larger level of confidence when I am roaming in the middle of no where.

FYI for those looking for a slight front suspension lift to compensate for our heavy truck campers, the Alldogs springs worked really well for me! Lifted it 1.5", so now I'm sitting 1" taller than stock in the front (since my weight brings it down a little bit). Here's my thread with all the details: https://www.tacoma4g.com/forum/threads/alldogs-offroad-front-springs-installed.10910

@gofastdan @trailhunger

First of this is an incredibly helpful thread @gofastdan with great contributions from the community. I'm specifically interested in your respective impressions of the Timbren Suspension Enhancement System (SES) (6000lbs) versions that I believe you both opted for. I'll be going down the coil upgrade route at some point but just waiting to see what options hit the market in the coming months. With that I'm looking for something to provide some load support in the interim and serve as a buffer to bottom outs (better than slamming down on to the stock bumper with load). Similar applications to you two at this point (mostly light/mod offroad) with overlanding and camping applications (at least for the time being).

Curious about ride on PNW logging roads with load, handling improvements, or other.

Lastly, if you were to do it all again would you just upgrade the coils/suspension and not bother with these?

First, yes, this thread has turned out to be helpful to lots of people, mainly due to all the great input from others wrt their experiences!

Yes, the Timbren version you're looking at is what I purchased. My thoughts, I'd wait on them and upgrade the springs first and then only do the Timbrens if you feel you need them later. When I purchased them no one that I'm aware of had found any replacement springs and the options for other solutions were limited. After putting the Lone Peak camper on the stock truck (almost stock, I had the Westcott spacers installed) I found I was routinely hitting the stock bump stops and it was not fun. The Timbren bump stops helped cushion the blows but they're taller so I was effectively sitting on them 24/7.

So to answer your question directly, with the options now available I would skip the Timbrens, install springs from either Dobinsons or one of the other options discussed in this thread and then run for awhile and see if you still are hitting the bump stops. I doubt you will. IMHO the Timbrens are only needed if you're throwing a bunch of extra weight on the back every once in awhile. For a constant load, upgrade the springs and call it a day.

TBH, I can't tell if I'm ever hitting the Timbrens. If I am it's only with the largest potholes. In the PNW the logging roads can be really nasty but even with the weight I'm running this truck handles so much better than any other truck I've ever owned it's just ridiculous. I am perfectly happy with my setup.

And...I tend to drive fast on dirt roads. I grew up driving on dirt roads and fell timber my first three summers out of high school (driving hours every day on dirt in my 1980 Datsun pickup) so I have little patience for idling down the road at 5 mph. The Prius on the way to the trailhead just needs to pull over and let me pass... ;o)

Also, you mention waiting for other options to hit the market. I don't see any reason to wait. There are at least three reputable spring manufacturers selling quality products in a variety of weights at very reasonable cost. If anything it's already overwhelming trying to choose.

@gofastdan sounds like you've selected a suitable handle! I'm with you, what's the point of crawling along FSRs when you can just plane at a suitable speed with any vehicle (and particularly now with proper rigs to do so).

Thanks for the feedback, kind of what I was thinking. Doing some calculations over the weekend then will set course on sourcing the appropriate coils/spacers (front). Like many, adding weight to the front end is an intended future step so will look to upgrade the front suspension when needed.

Out of curiosity, are you running any plating/armour? Curious whether that's been calculated into your overall weight.

I'm hoping to be out on the olympic penninsula for a quick trip in a few weeks, any idea how low the snowpack's sitting?

I'm running a full skid plate package from Talons Garage, 1/4" aluminum w/ribs. They claim only 71 lbs (32 kg) for the package and that's probably accurate. I'm also running the CBI Super Stock Covert front bumper (read my thread on that BEFORE purchasing) and a 12k Harbor Freight Apex winch. I thought with the bumper and winch I would need to replace the front springs but installing them didn't move the front end at all and I haven't noticed any adverse handling difference since installing everything. That said, I have no idea how much weight I'm carrying at this point but I'm sure it's a lot. Next time I go by a CAT scale I intend to weigh the truck. It's not going to be pretty.

Good question wrt the Olympics. I hiked out there the first of the year (Lower Dungeness River on the east side) and we were just getting into snow at ~3,000 feet (~900 meters), but a lot has happened since then and I'm certain the snow pack is much lower now. I live the opposite direction though (base of Stevens Pass) so I don't get across the Sound very often.
