Yeah, they're technically an aluminum/steel hybrid in that the mounts and high-lift jack points are made out of steel, but the overall slider section is made out of Al. My assumption is they should be a good bit stronger than the Greenlane sliders which I think are the only other Al game out there pretty much for 4Runners.

Considering similar sliders (they're technically not a boat side but am not sure what to call them) run around 120 pounds, they're a pretty neat option. Worst part of the deal is the cost by far ($1350).

I have a 3 year old who can use them as a step effectively which also made this style highly preferred to a tube slider.

I tried Eibach direct for the TRDP spring kit and ultimately, after placing the order with a guy at Eibach and waiting for 2 weeks in silence, I finally was told they are out of stock and new ones won’t go in to production for between 1-3 months. At the time of the order I was told they had 4 sets in stock. Apparently my order was actually sent to a distributor.

At one point I sent a message here to the Eibach guy who started this thread and never heard back. Ryan I believe.

I found a place online that had them in stock and bought through them. Currently on a UPS truck heading for FL.

Eibach sold out of them very quick. Unless a lot of vendors bought them up to sell higher price for a profit. When I got mine Tanner said they had a lot in stock.

Glad you were able to get them. I don't think you will be disappointed.

I’m glad we crossed paths, because your very complete write ups, the great pics and the review of exactly what I also want to do to my TRDP made it happen.

Can’t wait to get things as dialed in on my end as you’ve already done on yours. Thanks for your help!

Ditto on the THX to Dallas. Thanks for all the postings!

I was hoping to somehow squeeze 285s in without doing anything (suspension work, or removing mud-flaps, cutting the body, etc.) on the 2020 TRD Pro. The easiest thing for me to do is swap out with the Eibach springs.

I am looking at suspension options. I have read a lot of threads and what Eibach offers seems to be a good potential solution. I will soon be getting a 2021 TRD Premium.

The dilemma I am facing is do I go to 33" tires? I have a nice lift and tire setup on my FJ but 33" killed my power. I have never regeared. I tow an offroad trailer and that makes matters even worse. Soooooo. I am thinking about sticking with stock tire size with just a bit of a lift. Seems like this coilover system might be a good fit. Another option might be Billstein. I am going to add a front bumper and rear bumper so I will want to account for the additional weight in back while towing.

Pretty sure the math is the same with tire size and gearing on the 4Runner as it is on the FJ. Maybe a 275 tire size would have less impact. For me it is less about the cost and more about not robbing the 4Runner of performance for when I tow.

Looking for opinions and ideas. I will also keep reading!

Thanks

Unless you're purchasing a Pro, this lift will not work for you. The Eibach Pro Truck lift would be viable. If you are going full steel bumpers and towing a small trailer regularly, I think Dobinsons may be a better route to dial in a spring setup to fit your needs.
There is some really good information on this forum that discusses gear ratios and increased tire size. Good luck on your search!

Thanks for the response. I’ll keep searching. Not getting a Pro. I really don’t want to have regear from the get go. Too many other mods to do. Likely one of the lighter weight front bumpers just for a winch but the back will eventually have a dual swing out. Trailer tongue weight is around 300 lbs. I could do air bags to accommodate for that instead of heavier springs.

In my head I am thinking get an adjustable setup with better factory sized tires. 50,000 miles down the road or so I can then consider 33” tires, regear, etc.

FJ took nearly 8 years to build up and this one will probably be 8 months to a year foe most things. Lots of $$$$ out the door in a short period of time.

Eibach also makes the adjustable rear spring system. Rear is the same between Pro and other trim levels, so it's another option if you don't want airbags.

^this.
I went adjustable rears for raising when towing. Went adjustable Eibach front as well. can change height if they ever settle or if you add armor

Finally got around to taking a pic (can’t seem to post it though) after installing my Eibach pro springs in the front with toytec 1/4” top hat spacers and SPC UCAs. In the rear I have Dobs c59-509s and a 15mm shim on driverside. Added 285 KO2s. I ended up with 2” lift all around. Love everything about it so far. Had it on a rocky beach in a Montauk NY two weeks ago and it felt great. Will get it on some trails soon.

I had Spidertraxx on but the overlanding shop that did my tires and alignment didn’t have time to do my BMC so they took them off when installing the tires. I thought I needed them to clear the SPC, but the shop said I’m fine. No rubbing and no trimming. I even put the mud flaps back on.

I'm glad I could help a few out, but others had to help me first. I've done a few suspensions in my day. I did one suspension to my '06 Rubicon. Traded it. Did 2 suspensions to my '10 FJ. Then did one suspension to my '11 Xterra. Later did 1 suspension to my '13 Sport Unlimited. Then did 1 suspension to my '13 Rubicon. Then later did 2 suspensions to my '16 2door Willy's. Then did 2 suspensions to my '18 Rubicon Recon. Hopefully the Eibach springs are the only things I need to do to my TRD Pro. I love this vehicle and hope to keep for a long time. Of all the suspensions I've done this is was the least expensive, best riding smoothest install of any of them.

If I were looking to fit 305's would these work in combination with UCA's and a bmc?

Chopped the size of the pics...
