'21 TRD PRO SUSPENSION

Tried to find it but couldn't...has anyone made a stiffer spring for the new pro suspension?

I'm hoping Eibach will come out with something...otherwise, may sell this set up for something new. These are a bit soft and I'm afraid that with any consistent additional weight. it's going to be too much for these springs.

 

Wonder if a complete suspension with adjusters would meet your needs?
Suspension like FOX 2.5 DSC and ELKA 2.5 DC has dual speed adjusters and Kings 2.5 with adjuster has single adjuster. You can adjust the firmness you want in seconds. Or if want a nice soft ride. Plus they will give you a lift to fit bigger tires.

OME BP-51 also has adjusters but the reviews say its a pain in the A to adjust them as it needs to be done with the provided wrench.

 

Have scoured the net looking for same. So far, zilch.

 

this is where I'm at...looking at complete systems...which irritates me. I'm guessing something will pop sooner or later but I"m impatient.

 

Love love my BP51 very adjustable and height is a bit of a pain but rebound/compression is very simple with the supplied wrench’s I’ve gone from super stiff to Cadillac plush with a twist of the wrench

Rebound/compression adjustment is not hard to adjust? Need to remove the wheel to adjust or can adjust without removing the wheel. I guess the reviewers are wrong. Thanks for sharing your experience.

If you find any video adjusting BP51 rebound/compression without removing the wheel please share. I'm looking for adjustable setup for my Limited as well. Still thinking whether I should get another ELKA setup or try something different.

 

No if your truck is lifted and cock the wheel not too hard or up a ramp same operation
The height adjustment is a wheel off operation

well, I was looking at an ICON Stage 6 or 7...figured if I was going to change things up, I might as well do it all.

 

As far as I've seen ICONs with CDC valve will allow you to adjust the soft / firmness. It would be awesome to have stage 7 setup i guess but might not have to go that far to get CDC valve I believe. Not sure, haven't look at it much. Hope you pick a nice adjustable setup vs thinking of a non adjustable firm setup.

 

The eibach springs do tend to run slightly stiffer according to those who have them. Not sure how much weight you are wanting to add.

Just got off the phone with Eibach...was told they have had a prototype running for a week or so and to expect something in the next 30-45 days. Confirmed that the new perch is the delay after attempting to use a previously designed spring.

 

Great! Please keep me posted.

 

I can't get there...heres my issue with this set up...it's nothing more than a spacer lift to me, so it doesn't accomplish what my particular issue is-spring rate. If all I wanted was to put a larger tire on here, I may be ok with it. Plus, after watching one of the videos of them being installed, I get nervous. IDK...i'm not an expert in this area but this isn't a good solution, IMO. To each their own.

 

I hear you. We all have our itches. I'm of no mind to lift mine either. However, a stiffer spring to offset the new weight I'll be adding is mandatory.

 

Yeah, unfortunately for the 2021-2022 Pro guys, the 2021 Fox suspension change has made it harder for y'all to replace springs. Of course, the old Pro front struts just used a 3" spring, so there were many aftermarket options. Hey, at least your front struts hopefully won't have issues like the 2019-2020's did! Hopefully someone will release something soon!

All that said, would you guys not agree that lifting the FOX Shocks kind of ruins them in a way? Using a lift, thus changing the normal stroke area of the shock, would mean they don't perform as intended. Of course, if all you do is get a stiffer spring that sits at the same height, that wouldn't be as much of an issue. But I'm willing to bet that any spring offered gives a lift, as that's what most go for.

IMO the Fox suspension on the TRD Pro likes to be left alone. It's not like it'll instantly turn to doo-doo if you effectively lift it 1/2-1", but if you need something different, I'd suggest a whole new setup. You're obviously discerning hence the TRD Pro purchase... so use those funds you clearly have to do it right. My two cents...

 

My personal point of view is that lifting would certainly defeat TRD's tuning. To what degree? I don't know and won't personally be finding out. As to spring replacement in an effort to return it to its stock height? I'd be hard pressed to think that's a bad thing. But, that's just me. Others mileage may very

 

i don't disagree with anything you've said. I'd much prefer a stiffer spring...but arguably that changes the work of the shock, etc...all connected.

I had 5 whees/tires in the back of my 4 Runner last week. Here's what I found out...the ride was noticeably different with ~200lbs. Where the weight was (second row folded and whees/tires spread out) had a huge impact on how it handled...and the best way I can describe it is "greasy".

Fast forward to the future...roof rack, RTT, winch and possible load in rear will do what? Carrying my family of 5 is one thing...but adding the aformentioned to it and family...maybe pulling something...and I have got to imagine it will not be any better and will be worse.

I'm open to opinions and thoughts...and maybe, I'll do all that I stated and THEN make a switch if it feels bad.

 

I completely agree. Unfortunately, I simply doubt a stiffer spring will be offered that attempts to keep it at stock height.

In response to both of you guys, I think we are all on the same page and agree with each other. When I first started looking into suspension, I honestly wanted to keep the stock spring rates. I moved to a "truck" from a car initially to combat the crappy city roads, so I wanted something plush that could absorb all the bumps and not break a sweat. But once I started thinking critically about lifting the truck, slightly stiffer springs started to make sense, and I now am not surprised that, basically, all lift springs are stiffer than the stock ones. This helps even more if you are adding much weight (which, personally, I don't plan to do).

I'd say add the weight first and see what you think. I don't have a LOT of gear when camping, but my Yeti 65 loaded up must come in at near 100 lbs. Still, I bet all of my camping gear combined will never get close to 200 lbs. And since my sliders sit in the middle and down low, they really don't seem to affect much weight/sag wise.

 

Would they not overcome a reasonable amount of sag caused by, say, the addition of a winch and aluminum/steel winch mount? I'm hoping that would be the case. But what the hell do I know. lol

 

What I'm saying is that they will probably overcome that sag, and then some.. so you'll be sitting higher than stock, even with the extra weight, due to the aftermarket springs being both stiffer and longer.

For example, on the TRD Pro Bilstein setup, the 4Runner came with ~550 lb/in springs that were 13" long. Fortunately for that case, the standard spring type meant lots of aftermarket options. Still, even though there is a Dobinsons offering, Kings offerings, two from Bilstein (standard 6112 spring as well as "heavy duty"), and even the FJ Cruiser's "Trail Teams Special Edition" TRD Kit spring, they are all both longer and stiffer (14" and 600 lb/in or more) than the stock TRD Pro spring. So swapping to even the least extreme option, the 14" 600 lb/in spring, resulted in a 2" or so lift. No one bothered making anything that was just a "little" bit more, probably because it seems that most who like to lift their 4Runner don't want a "little" lift or to add a "little" weight.. People seem to go big or go home. I'm not that way myself.. but I digress..

 

I hear you. Back in the day we'd have cured the over lift buy reducing the height of the spring(think cut). Knowing it would stiffen things up a we bit more. Always in search of the perfect setup. Some things never change, but the way we go about it may.

That said, it'll be interesting to see what's around the corner.

 

Haha, perhaps that's an option! I haven't seen anyone talk about cut springs in a long time, but when I was in high-school we used to joke about cutting the springs on our Accords and Maximas to lower them... knowing it was.. "ill-advised" .. so we never actually did it. I suppose technically it could be a non-issue, if the case was just right and the individual knew what they were doing.

 

Thoughts on this? Toytec front spring replacement. Includes new front coil spring perches and 700lb rate coils. I have the wescott lift right now but am considering this route after installing my bumper and winch.

 

I think they will give lift but will not give much articulation like a suspension lift as the fox suspension are setup for stock height. I personally like to go with a suspension lift than just adding a spring and spacers.
