You can directly switch them; you're just going to need an alignment. I dont think it gives you any lift.

 

Should be a relatively straightforward replacement, but you won't get any lift. You should only get a softer ride from switching the stock Sport Hitachis for the stock OR Bilsteins. Both aren't adjustable.

EDIT: sorry, brought up Sport shocks out of nowhere. I'm not sure what's on the SR5, but I do know its the same ride height as the OR.

 

Same height, better ride. Direct fit.

 

...my OEM Off Road take offs are for sale in the buy sell trade forum.

 

A more correct answer is "it depends."

Do you have a 4x2, or do you have a 4x4? Do you have a 4 Cylinder, or do you have a V6?

I have a 4x2 4 Cylinder, and I put springs on from a 4x4 V6 (TRD OR)... imagine my surprise when that gave me about a full inch of lift!

Well duh, it makes sense, the springs are accounting for a V6 and a Tcase / front differential. When you put them on a truck with a 4 banger and no front axles, there's a lot less weight and you get a higher static height.

Bear in mind though that my case was the most extreme, springs from one of the heaviest Tacos going onto one of the lightest Tacos.

So then, if you do have a v6 and 4x4, there's no change in the expected load. If you do not, you're going to get somewhere between "nothing" and "about an inch".

 

If you want to get into semantics, he asked about replacing only the shocks and struts, not springs, which you brought up independently. Since these cars don't have struts, he effectively only mentioned replacing the shocks. Replacing the shocks will not raise the truck. Replacing the whole coilover may lift the truck, depending on [insert what above post said here].

 

Reasonable Assumption is that you are swapping from Same type of Truck (body style, engine, driveline, etc.) Duh.

example: DCSB TRD OR 4x4 to a DCSB SR5 4x4

or

Access Cab 4x4 TRD OR to a SR5 Access Cab 4x4

 

I thought the off roads did have a factory 1" lift. I assume it's because of the front coilovers. Doesn't a 4x4 offroad sit higher than a SR5 4x4?

 

1" lift from previous Generation

Ahhh. Ok

 

Sorry I posted "wrong" information. I simply did the exact swap from my SR5 to Offroad shocks and did not get any noticeable lift.

 

If you want to double down into semantics-ville shocks can alter the ride height, but not in any appreciable sense (as in, 1/4" or so tops) as long as they are working and installed properly. Shocks are dampers that have to be pressurized to work. That pressure acts on the spring. I'll spare us all going balls deep into the math but it's literally on the order of adding or removing 30 pounds of weight to the bed, so, barely noticeable but it is a force acting on static ride height...

My apologies for being a little heavy-handed. I was just hoping to flesh out the info given and I shouldn't have been that ornery.

 

I've got a timeshare.

We're not talking about whether changes in shocks can change rise height. We're trying to answer the question: will doing what the OP described (replacing stock SR5 shocks with stock OR shocks) change ride height? Can you provide an answer to that question without getting into how tire psi can change ride height?

 

I can, actually, with observed data from my truck!

I replaced only the shocks in the rear, and kept the same leaves. SR / SR5 Hitachi shocks to TRD Off Road Bilstein shocks, swap only. No spacers, no nothing back there. Merely jacking her up, undoing the 2 bolts on either side, and replacing ~1000 mile Hitachis with ~1000 mile Bilsteins.

Bed unladen both times, same tire pressure, almost same fuel load (20 mile round trip between measurements, let's call it 1 gallon difference, so 6.3 pounds), and it was driven to let the measurements settle, as opposed to freshly down off a lift.

It's about as close to a true scientifically controlled experiment as you can get.

The lean was still present at 1/4" side to side, and I had raised the rear on both sides by 1/4" of an inch.

 

I stand corrected. I am curious as to exactly why you gained what you did.

And why didn't you lead with this? Instead of leading with the spring swap?

 

My understanding of it is that while the vast majority of ride height is the spring, the pressure of the gas inside the shock does cause some upward pressure. You can push on a shock with your hands and compress it, so it's not a lot.

Progressive spring rates throw a monkey wrench into this whole equation so let's just imagine a single-leaf system for an example. Let's say this leaf is a 1000 lb/in spring, and the truck puts 1000 lbs on that corner. Easy peasy math, that means the suspension droops one inch at static ride height. But now let's put the shock on. The shock is pretty beefy so you have to push with about 50 lbs of pressure to compress it. Well now what's actually happening is you have what amounts to a 1050 lb/in spring supporting 1000 lbs of weight. Now your suspension is only going to sag .95"

In an ideal theoretical sense a damper shouldn't affect the ride height, but that's ignoring the practical fact that a damper has to be charged with gas (and thus pressurized) to work.

I'll have to cop to being lazy. I just assumed that up front, most people are replacing the whole coilover assembly with one from a TRD Off-Road as it's way easier and doesn't use a spring compressor.

It's also the way most of the take-offs on the marketplace show up, since a lot of people go to aftermarket coilovers and simply pull the whole assembly.

Did I mention it's way way easier to install?

 

My understanding of shocks must be wrong. I thought that if you took a bare shock (no spring) and compressed it, it wouldn't rebound to its original position; it would only dampen the motion caused by the force you applied to compress it. I admit, I haven't actually done this myself, it was just my understanding. I understand that on the front end, the whole shock/spring assembly is a lot easier to change out, while its a lot easier to change out only the shock on the rear end. My apologies for being snarky, but at least I learned that my knowledge wasn't as complete as I thought it was.

 

It will rebound. If it doesn't, it's shot.
