The weather was too nice today to not take advantage of so I swapped in the 3FE 80 series rear springs that were originally under my friends ‘91.

This was a bit of an experiment as I couldn’t find evidence of anyone else attempting this or conclusive evidence of 80 series springs being identical to the 100 series. I find the latter hard to believe as the 100 carries a fair amount more weight than the 80 but I digress. OEM 100 springs are well known to give the Sequoia about 2” of lift.
I only wanted an inch of lift or less, just enough to get the rocker to not point uphill anymore. Yes, I could have used spacers but I had these in stock so I figured I’d try them out for science if nothing else. These 80 series springs are asymmetric, the drivers side measures 18” and the passenger is at 17 1/2” (Later 80 series springs are supposedly taller). They have 6 1/4 coils and the wire diameter is .600”. Conversely the Sequoia coils are identical side to side. They measure 16 1/4” tall, have 5 3/4 coils and the wire thickness is .650”.

I tried to do this test as scientific as possible in the event that I have to get back in there and change things. So I filled the tank, spare and 3rd row were in, etc. I also made identical measuring points on each side (blue tape in the pic).
And the results are...
Rear end has come up about 16mm (5/8”). I think I like the way that it looks but I’ll have to stare at it for a few days. At least the rocker isn’t pointing up hill anymore!

I can’t yet comment on ride quality but it seems similar. I ended up sacrificing the sway bar end links so the arse is a little wobbily right now. I’ve got replacements on order from McGeorge. Pretty happy so far though.
