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

[Cry_Borg]

This is such a great thread. Led to me getting the Dobinsons 821s installed on my '24 DCLB OR. Just had the work done so have yet to get all my gear on -- it's crazy how much the rear sits up without any payload, even with a 2.5" lift in the front. Will have to measure, but iirc the guy at the 4x4 shop mentioned about a 5 inch increase on the fender height from stock (of course due to the tires as well.)

I don't think I'll quite hit 1000 lbs for the payload, but should be close. Was originally leaning more toward 819s, but they've been on backorder for quite some time and it seems like a couple of you guys here are happy with the heavier spring. I hope it was the right choice.

I stupidly ordered a pair of 822 front springs as well (in anticipation of a steel bumper and winch), but turns out they are not compatible with my suspension kit (they should work on a stock setup). Should've called King and talked to them prior to just impulsively getting the springs.

Anyway, I'm past Dobinsons' return window by about a week so if anyone is interested in these, shoot me a message, because they're now for sale. Red, new in box 822s (C59-822R)

So did everyone swap out these coils without changing their rear shocks? I know generally the idea is that we are compensating for the extra weight in the rear end, and therefore not getting a lot of lift compared to a stock unloaded truck, but given that the Dobinsons website is still saying I should be getting 1.5” of lift I was wondering whether I would need a longer rear shock?

I've probably read every post out there wrt rear coil swaps and I'm not aware of anyone replacing the shock due to length issues. Now, some might have replaced the shock just because they were completely upgrading the whole suspension with something like a King suspension, but that's a different use case.

In my case I originally installed the Westcott Designs rear spacer, which added an inch to the rear. No issues with the shock travel but once I started adding weight the spacer was no help. I replaced the spacer with the 819V spring and have about an inch of lift, so almost exactly where I was with the spacer, but I'm also probably carrying well over 1,000 lbs of weight. If I had it to do over I probably should have went with the 821V but I was the first to try the springs so there was a bit of guessing going on. Bottom line though, a one to two inch lift on the back seems fine with the stock shock.
