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

[MtnToad]

Thank you so much for the update. 23 3/4 seems to be right around the sweet spot I think I will be around 600 pounds too.

Did you lift the front?

No, I left the front stock. I just couldn’t justify spending $1200 to lift the front on a truck w 600mi with how I use it lol. Though I did find the height of the 819’s to be nearly perfect but was way too much rake with the front stock

2024 Toyota Tacoma Trailhunter Suspension Mods

After researching, reading forum, and consulting with Mule Expedition Outfitters, here is my current solution for offsetting the increased weight of my truck. I previously posted a detailed list with weights for specific items kept onboard the truck.

FRONT: Bumper, Winch, Lights 235 lbs Front
REAR: Leitner ACS Forged Rack, Rescue & Personal Gear, Decked Drawer, CargoGlide 760 lbs Rear

TOTAL APPROX. LOADOUT = 995 lbs

SOLUTION:
Installed Dobinson's Springs - RIDES SMOOTHER, SEEMS AT LEVEL (Not yet measured)

• Front Coil Spring Specs: Front offset needed approx. +235lbs
  • C59-822 (50mm- 2") 110-220lb Load
• Rear Coil Spring Specs: Rear offset needed approx. +709lbs
  • C59-819V (30mm - 1.25") 440-660lb Load

If more is needed I can go to the 821s in rear or add a spacer to front or back. No real need or desire to replace my suspension or lift the truck more for my use case.

Tires are Cooper 265/70R18 Snowclaws on OEM wheels for winter, Falken 285/70R17 AT4Ws on 17 inch Method 703s for most of the year.

Will see how this works out. Still have less than 900 miles on my Trailhunter.

Thanks for posting. I currently have a Westcott spacer on the front but I ordered a bumper today, CBI Super Stock Covert, which was the most minimalist bumper I could find that would fit a winch. I picked up a Harbor Freight Badlands 12k winch last week for a great price.

It will be a couple of months before I get the bumper but I'm guessing once I get it all together I'll end up pulling the spacer out and go with the same springs in front. It's good to know you're happy with them!

You are welcome. Remember, I do not have miles on this yet... but I am pretty confident I am in the ballpark. Back in the day when I was building Fast Attack Vehicles for 2/1 Infantry, I had to do weight calcs for each version of a dune buggy for lift purposes (Blackhawk, CH-47). I like to think I got pretty good at estimating what things weighed... and used that lesson here. It is never an exact science, but you can dial things in well over time.

This looks pretty awesome. Just for my understanding, the C59-822 coils fit the stock shocks?

Also, when you can, please share your measurements.

I bought the 819s but I am now looking at what to use to lift the front and a coil lift would be better than a spacer lift and I am wondering if I can replace the front springs of my TRD Off Road. I know the shocks are different than your THs.

Call Dobinsons and talk to them directly. Those springs are a confirmed fit for my Trailhunter and my local 4WD shop put them on after also verifying fitment for the 24 Tacoma. They installed without a problem.

I called Dobinsons before ordering after reading about the shocks on the Forum. I do not know about any setup other than the Trailhunter which came with the Old Man Emu 2 in lift in front and 1.5 in the rear. What I was after was offsetting the weight of my truck with my equipment added.

Just installed 819's installed on Tacoma Off Road 5' bed with ~850 lbs of constant load... Wanted to share my stats for those deciding between springs. I have a Tune truck camper with a kitchen setup in the rear, approx 800-850 lbs of constant weight (the Tune was weighed at 500 lbs on CAT scale, haven't measured my build yet but I've estimated those weights).

	Stock rear springs	819 rear springs
+0 lb load	37.75"
+850 lb load	35.75" (-2" below stock)	38.75" (+1" above stock)

My measurements were taken from the center of the rear tire hub to the start of the rear tire fender while at the same parking lot next to a stock Off Road 5' bed truck at the dealer.

Front is sitting 0.5" lower than stock.

I've aggregated some other numbers from others earlier in this thread, and converted my measurements to the normalized format from the center of the rear tire hub to the start of the rear tire fender...

	Stock rear springs	817 rear springs	819 rear springs
0 lb load	+0 above stock (23.25")
50-100 lb load		+2.25" above stock (MFR)
175-330 lb load		+1.25" above stock (MFR)	+2.25" above stock (MFR)
500 lb load		+0.5" above stock (23.75") (MtnToad)
440-660 lb load			+1.25" above stock (MFR)
785 lb load			+1.25" above stock (24.5") (MtnToad)
850 lb load	-2" below stock (21.25")		+1" above stock (24.25")
