My truck is outside right now and fairly empty at roughly 7400#. I’ll take measurements. Fully loaded it exceeds 8400#.
I have been running the 319 springs with a 30mm spacer in back in this pic. I love the springs. Can handle high speed hard hits and fast curves in the mountains. Tall...
Andrew, My truck is also super heavy especially on the rear axle. I have had multiple coils over the years 863,864,Slee heavy. I now have been on a set of 319 rear coils from Dobinsons and am completely happy and think finally done with my suspension setup. They are the heaviest rated coil I...
Theres already a thread for the MRR Dobinsons adjustment actually. Dobinson MRR (A) Move this to that thread and as more people get these shocks on their 80s it will be a good thread for that.
Does anybody have the Slinky coil specs for new part numbers and the corresponding lift and application:

@GW Nugget it seems the part numbers you have in...
The way I displayed the info might have made it confusing. Edited. I got all the coil specs from Post #114 of this thread and cross referenced with the coil info that Dobinsons supplied on their Amazon page. I do know they are all Variable rate coils. I’ve been looking at getting either the 2”...
Looking at Dobinsons coils on Amazon it says the C59-223V is a Variable Rate coil that will give 2.0” of lift with 220# of constant weight. But with the specs on those it almost seems impossible to get 2” of lift off a 17.5” coil!
I have found 5 different rear variable rate coil numbers...
I’m in the same boat as you. Started off with a budget lift and over 3 years have spent more $$$ swapping springs and blowing shocks than if I just went with a Slee or Stage 4 Slinky full kit in the first place!
All this info in one place is great, now the problem is there’s TOO many choices...
Yeah:
TJM Front 50mm- 770FR80C: 21.2”/20.8” free ht. 17mm coil, 10.2 winds
TJM Rear 50mm - 770RR80C: 20.2”/19.8” free ht. 17.4mm coil, 8.8 winds
They are a taller coil with more winds vs. OME medium/heavy which likely means a more supple ride and lower spring rate. Very good on an unladen 80.

GW you da man! This is a great thread. Tire rub on bottom out specs in this post assumes tire sizes with the stock 16x8 zero offset FZJ alloy rims? I know with wheel spacers and different rim spacing, tire rub varies.
