Feels like my rear end is bottoming out on 2000 4runner going over bumps. Recently replaced rear shocks figuring that would improve but doesn't seem like much improvement. Other ideas? Need new coil springs? Pic enclosed of rear spring. Should there be more clearance for the enclosed bumper? Truck seems level looking at it from the side.

Looks like it to me. Ive had airbags for like 5 years, so i can't compare mine but you have like no travel it seems.
If your fine with your height a cheap fix would be to cut off the bottom of the bump stop but idk how bottomed out your shocks are.

That cone bumper is very soft (not the frame bumper that is hard), but you will still feel it engaging over bumps.
Measure the center of the hub to the fender lip - I bet you are down around 19" or maybe even below. Your front might also be hitting the bump stops with some regularity.
New OE springs all around are your best bet unless you want a lift. (new springs will just get you back to stock height of around 20" hub to fender)

You should definitely have more space than that. It should be 3-4". If money is tight, you can get the Moog springs.
18.5" on front, 18" on back... guess it is squatting! I guess I will do autozone coils for $60 on back, $90 on front with lifetime warranty. Figure I will keep the truck a while so maybe in another 15 years, I will do em again for free?
Get some squeaking in the front when running over bumps, guessing the A arm bushings? maybe replace those while I'm at the front changing those lifetime shocks along with adding new coils?
Thanks for all the input "guys"!

what I'd do.. after lots of research, if I wanted to keep stock ish height. I'd find a used set of springs off a 5th gen 4runner. front and rears fit they will give a little lift IE 1.5 over original stock height. You are under original stock height. You an find a set on CL for under a 100 bucks front and rear. Heck I found someone giving them away. you will get OEM Japaneses made Toyota quality. for cheap. and a set of Bilstein 5100's.
You will never have to replace them again.
I think the set of Bilsteins are about 350-400
I wouldn't trust non OEM springs to last and to get them new from the dealer would be way expensive.

I had 5th gen and FJ springs when looking to replace stock rears. Went with FJs because they were slightly shorter, but spring material was wider in diameter. Added those to 5100s but no longer use the FJ springs since I got LC coils. OP send me a message if interested. I loved the ride and slight rake that came with the FJs in back, was better than stock.

I like the idea of maybe a little higher rather than shorter as long as it doesn't affect anything else? 5th gens all around if it keeps it level sounds good? Sooo, FJs are more like the height of original 3rd gen springs but thicker?
I'm down for keeping the money out of Autozone but already have replaced the shocks years ago on my 4R soooo, just replacing them for 2nd time now 10yrs after first time. Freebies from Autozone...
What are durabump bumpstops and who is plasticsguy? lol Why replace those?
LC coils? LandCruiser?
I see ZERO coils on Craigslist for 2010-2017 4R :-( ebay might work. junk yard?

If you are not looking for a lift front and back, just get yourself a set of OEM replacements, or go for the '99 talls' for a little rear lift. Search will find you the part number. There are aftermarket options that are better than nothing.
Experimenting with FJ springs or 4runner springs from other generations will be throwing darts. It will be a significant lift from what you have now as your measurements are low, how much is anyones guess. People seem to get varying results with these. It may work but it may lead to a lot more work also.
And no, the 2019s would not match. You MAY be able to get them to fit, but the results will be anyones guess and the fronts will need to be disassembled as only the springs may be useful.

Seems he's done some research on the matter and 5th Gens all the way around might be the way to go if I wouldn't mind an additional inch or so from the stock set up.... sounds great to me... used 5th gens are going to have way less miles on them being sold used and cheaper than new oem 3rd gens.... as long as it doesn't affect other suspension stuff and I can get the springs in there without a wrestling match? Do have a spring compressor but I'm guessing I can just let the rear be supported on the frame with a jack and I can pull the old ones out after maybe just a little compression? Do the front struts line up if I bought some fronts with coils off of a 2010-2018? or do I need to extract the coils from them?
I'm looking at a set of 2019's that the person says will line up with a 5th gen so that was the reason I asked about the 2019's

Found the info on those but seems more for wheelin'? I am mainly streetbound but occasional out on a dirt road. If the springs are replaced, shouldn't be hitting the bump stops all that much anyway right? Worth spending another $200 to replace stops that seem in good shape for now?

4th/5th gen and FJ Cruiser *springs* fit (front and rear). The front shocks won't fit in any way. The rear shocks "fit" but are 2" too long and will bottom out before you hit the bump stops.
Ride height from the 4th/5th/FJ springs will vary slightly, depending on the vehicle they came from (engines, options, years, etc.).

Springs will fit all around on from a 5th gen. Front shocks will not. Rear shocks will but the compressed length is too long. so not suggested.
Use the search feature and you will find lots of people that have done this and can get an idea of the results.
Here is just one of them.
Solved: FJ Cruiser Spring Lift for 3rd Gen 4Runners
rear thru and there is discussion on 5th gen 4runner as well.
Lift will be mild enough to where you do not have to do... pan hard correction, extended brake lines, front diff drop, rear bump stop extensions ext... these are typical of a 3" plus lift.
Duro bumps are for off road use. you will not need them
LC is landcruiser. you will get 4-5" or more of lift so do not do that.
as front as options for the front Shocks I do not know if you can use and OEM style (IE KYB from autozone or similar).. you might have to do research on that. I feel like most go with the Bilstein 5100 because they are pretty affordable. and give great ride characteristics.
spring compressor is not needed for the rear install. just droop the hell our of the axle. do research there are you tubes of both front and rear installs
ALL Toyota springs are color coded. Get the colors off the ones you want to buy and use them as a reference when researching and see what others have gotten. I can tell you for example I have seen 5th gen SR5 rear spings with the same color code as Trail Premium. So they are the same spring.

Save you some time... it's on page 7.

used 2017's up front

used 2018's with Tundra Bilsteins
per [MENTION=315178]J.cole13[/MENTION]
"I have the fronts on the second ring. I'm currently sitting at 21.25 inches in the front, which is 1.75 inches taller than my stock height of 19.5 inches the bottom clip gave me 1.25 inches.. and so I took everything back apart and went to the 2nd perch.."
Was double checking my work to make sure I don't look like as ass. Haha

I had a similar issue with mine even after new coil springs. So I added firestone ride-rite air bags. Lifted up the rear and improved the ride big time. I installed them myself in about an hour. Part number 4135
