Suggestions on Progressive front shocks needed

Can't tell who "the same guy who couldn't wrap his head around..." is from your post. I run 6112's specifically for their digressive valving after removing the anti-sway bar on a truck that sits at GVWR dry.

 

Not you the other fella that was more or less saying digressive as a term is marketing mumbo jumbo. There was a past thread with a loooong debate regarding how dampening will have 0 effect on body roll or nose dive after changing from stock off road shocks to 5100's

 

3rd gen trucks (other than the Pros) actually come with 700 lb springs from Toyota, but they are set up with very little preload, which allegedly keeps them from riding as rough as a typical 13" 700 lb. coil would on a light truck. (I understand preload pretty well, but I don't fully understand why Toyota's approach actually works, but that's what I've read.) So I imagine the Dobinsons 700 lb. springs that are meant for lighter loads do essentially the same thing. Generally, places that set up coilovers for competition (e.g. accutune) recommend using the lightest spring possible that will hold your vehicle at a given height, but the advantage of running a 700 lb. spring with little preload might be that it better accommodates being loaded down more heavily on occasion.

 

Dang! I had no idea they bumped up the spring to 700 lbs. Good piece of info.

 

3rd gen has a different coils on SR/SR5/Limited vs Sport/OR.Which part # is 700?

 

If I recall correctly, the coils are all the same except on the pro. Only the shocks differ.

 

What's the intended purpose of your 2WD truck? I notice it's lifted. You plan to mob it in the dunes or just on pavement?

 

Color coded differently, plus different part # based on trim, wheelbase, etc.
One of the sources. Search for coil spring for 3rd gen

Following your link and excluding TRD Pro coils (which are 650 lb., via Fox) and excluding use for 2WD (of which I have no knowledge of spring rates), we are left with three spring options:

If I am reading the descriptions correctly, one spring is for the 3.5 left side, one spring is for the 2.7 right side, and the third spring is for EITHER the 2.7 left ~or~ 3.5 right. That would indicate all three springs are in the same ballpark of spring rate, with only minor differences in length, to accommodate for Tacoma lean.

When I have bought OE coils, the color codes indicated which side of the truck they were meant for. But when we buy coils for aftermarket coilovers, we don’t buy side-specific springs because aftermarket shock bodies allow for fine-tuning the coil preload to correct the Taco lean.

Therefore, it is still my belief that all 3rd Gen Tacomas (at least through 2021) use a similar spring rate in the ballpark of 700 lbs. I might be wrong. But this was also the generally held belief on Tacomaworld, esp. after the posting of the following thread, in which Toytec benchmarked 3rd Gen springs.

Accommodate tacoma lean is another myth.
See description for the coil position.
I have OEM coils on the shelf that are identical by length, marking, etc.
Everyone is posting to that link for 700 reference. There is no supporting documents attached to that posting.

 

Excuse the interruption...this kit looks like TRD Lift Kit shocks similar to the ones on the TRD Pro.

I'm verifying if this TRD Shock upgrade ordered from the dealership requires different spring seat/coils other than OEM setup.

Also asking dealership what factory height settings...which I'm told is 2" from my Toyota Parts friend I know in NY.

So, these are digressive since they are Bilstein--I'm good with that for daily driver.

 

Nevermind about my above question...the TRD Pro Shocks are Fox Shocks...which requires new spring seat/coils.

 

Did you read the description on the image you posted?

Also, are you saying Toytec, the vendor that directly posted, just made up shit?

And are you saying everyone who has experienced Taco lean, and then corrected it with preloading their driver side coils more, is either delusional or has faulty tape measures?

 

More delusional tacomaworld members on this link too, (count me as one of them because my left and right OEM coils were also color coded differently from the factory, as were a set of takeoffs I bought from another truck. Maybe Toyota is also delusional.)

It doesn’t matter though. Do what works for your truck. Hopefully OP does not experience, or does not mind, a little lean, and if he does, it’s okay, because it’s easily correctable.

 

That post was by Toytec, which sells lift kits and Toytec-branded suspension components. The 717 lb/in number would have come from Toytec's own measurement.

By way, 5th gen 4Runner front springs have measurably different wire diameter and number of coils left vs. right. Toyota has been doing springs this way for a long time, with leaf packs too. Springs don't require unique tooling to manufacture, so Toyota can have 10 different springs per model without much added cost.

 

I ended up going with the Dobinsons, with longer coils and low spring rate, very impressed.

 

Some sneak peaks of install. I also had to make custom extended ABS lines about 14 inches longer than OEM. I literally found ZERO extended ABS lines!!!

 

I have 4 inch maxtrak spindles. I ended up with over 8 inches of lift total.

 

I’m super curious why you needed to add 14” of brake line. Except for long travel setups, the existing front brake lines are long enough for up to 3” of lift. So 5 or 6” should have been plenty. (Disclaimer: I don’t know as much about lifting 2wd trucks.)

(Or are the extended brake lines for the rear?)

 

When you install the spindle lifts, it relocates the ABS plug like 6 inches lower and at a funny angle. So with just a spindle lift, unless you want to un do all ABS lines from the brackets and let them hang you need to do a little extension or they are just there hanging. Take a peak under and in the wheel wheels of some trucks with spindle lifts and see what all is hanging. .

Or, on my 2nd gen i just kept a few ABS sensors in the truck and some electrical tape. Especially if you also add coilovers and were up to 6 or 7 inches There was a 50/50 shot by the end of the day on trails and mud and sand, etc, I would still have working ABS sensors. and a 1 in 5 chance that I would still even have all of them.

Even in the back once you get to 6 inches are so unless you free the ABS lines from the brackets and let them hang they get stretched to the limits.

This time since I was changing everything and going to try to go the heighest I ever have I figured I would do the ABS lines too and get it over with.

It has settled some after some flexing but, Right now I am at 28/45, 28" center to fender and 45" fender to ground on 325/60R20's

I extended all the actual brake lines I 10 or 12 inches I'll have to double check
