Bilstein 5100 1.75 with driver side rear 1.5 spacer pics

[Will733]

With Bilstein 5100's set at 1.75" in the front and a single 1.5" Daystar driver side rear spacer... Here are the measurements:

37 2/16 - Front/Driver
37 6/16 - Front/Passenger
38 3/16 - Rear/Driver
38 4/16 - Rear/Passenger

The 1.5" spacer added about 1" to the rear of the drivers side and 0.5" to the passenger side due to the rear springs being located a bit towards the center of the vehicle.

Looks good man love the charcoal grey got pretty much the same setup. Are they duratrac tires?

Thanks man, so you just have the 1 single spacer too? Looks good man...

Yes, those are Duratracs. BFGs are nice too and had them previously.

Very nice :thumb3:

Actually before toytec stopped carrying them I got a set of 1 1/2" raised eibach springs for the rear, they were on sale for about $130 so i got those instead of the spacers.

Sorry to revive an old thread, but what's the benefit of putting the 1.5" spacer on only the driver side rear, as opposed to spacers on both driver and passenger side? Has this affected your ride at all?

Just purchased the same Bilstein 5100 & Daystar spacers setup myself so doing some digging around the forum. Thanks for any input!

I was just about to ask the same question myself lol.

compensating so that you dont have a reverse rake.

 

[desertred]

I think the the answer is to compensate for the driver side lean due to the gas tank being offset toward the driver's side. With the gas tank sitting more on the driver's side, many folks noticed a driver's side lean from additional the weight of the gas (particularly with a full tank). Placing a rear spacer at the rear on the driver's side only may be an attempt at correcting any lean caused by the fuel tank placement.

BUMP! Finally found this thread again!

Will733 (OP) - How did the single 1.5" spacer in the Driver's Rear affect handling and cornering? I'm also looking to level my driver's side lean, and want to approach it the most appropriate way WRT handling and such. I don't want to end up with varying spring rates around my truck if at all possible...

I'm pondering using the 5100's set to 0.85" Front Driver and 1.5" Front Passenger (stock springs) to achieve a similar result (and to level the front), but I'm not sure which method is superior.

PS - I have approx 250-300lbs of audio gear in the cargo area - so the rear is a little lower than stock "as-is".

Does anyone make a 1" Rear-Spacer for the Driver's Rear spring? That would seem to be about perfect in my case (along with the fronts set to an even 0.85").

PS - I also just saw this 1/4" front spacer (said to raise front by 1/2"):

Thoughts on running 5100's at 0.85" plus this 1/4 spacer on the Driver's Side?

PS #2 - I also saw this 10mm REAR spacer:

Seems like that's gonna be the ticket - Thoughts?

Thanks for any clarifications from the field. :wave:

Randy,
First a spacer does not change your spring rate. It is what it is and whatever rate it was designed for is the same. Only way to change rate is change springs.

 

[Randyman...]

Thanks 1E! I was hoping you'd chime in.

What about the 5100's and the adjustable cogs (and using them to offset the lean)? I guess those are mainly affecting spring pre-load - but doesn't that also mean the spring will react differently "at ride height" than the same spring w/o the additional pre-load (isn't spring rate non-linear to a degree)? How would the Driver's at 1.5" and passenger at 0.85" fair in this regard?

Same thoughts with a single rear-spacer: Isn't the driver's side spring taking more weight when "spaced" - also slightly affecting that particular spring's pre-load "at ride height" compared to the passenger side w/o a spacer? I'd assume these disparities are minor - but I'd like to get some clarification on my uneducated assumptions.

My current plan (hoping to do this once) is to go with the full 5100 set-up with fronts set at 0.85" (stock SR5 springs), and add the 10mm rear driver's spacer (also with stock SR5 springs).

I'm planning on ordering the 1/4" front driver's spacer, but not initially installing it, and see how the lean ends up. It seems like adding the 1/4" front Driver's spacer is a fairly painless procedure (don't have to completely remove the shock or re-compress the spring to add it "after the fact" - correct?)

I'm thinking spreading the lean compensation between front and rear is the best option - and I do have additional driver's side weight in the front with the huge 31M battery in the stock location.

Does this sound like a sensible plan to spend my money on? I REALLY want to lessen the nose-dive, and slightly level the F/R rake in the process, too. Addressing the driver's lean is a huge bonus - but I'd like to nail it during the process to appease my OCD tendencies

Thanks for your expertise on the matter - I sincerely appreciate your efforts on this forum (I've learned tons from you and Antman amongst other knowledgeable members of this awesome forum).

Sorry so wordy - It's a curse of mine...

Something to think about. This relates more toward race cars but holds true for anything on 4 wheels....

If you've got equal rate/length springs l/r and the vehicle leans to the drivers side, then the drivers side is heavier than the passenger side. If you attempt to raise the drivers side front you are in effect actually putting even MORE weight on the drivers side front spring as well as the diagonally opposite corner. Smaller adjustments we are talking about are not dangerous, but keep in mind you are changing the weight distribution when you adjust your coilovers (or add spacers to one side).

Toyota had a stiffer spring in my drivers side front from the factory, so i guess they know the issue exists.

 

[Randyman...]

That makes perfect sense, ATL4R. I'm certainly not a suspension engineer (I'm an audio engineer :tongue1: ) - so I'm likely using incorrect terms, but I believe I understand the premise.

So, in your opinion for the driver's side front, is it better to use the 1/4" spacer up top (offsets the entire coil-over assembly down by 1/4") - or to set the 5100's to 1.5" driver's and 0.85" passenger respectively (affects spring pre-load to a degree)?

Then for the driver's side rear - would you say the 10mm driver's side spacer is a good solution - or would a slightly taller driver's side spring or slightly stiffer spring rate be a more appropriate way to address the lean/weight imbalance (with handling and ride quality in mind)?

I'm likely ordering the full set of 5100's and spacers I linked to today - so any clarifications are greatly welcomed before I drop the cash!

Thanks for everyone's expertise!

I'm an impatient SOB! I decided to order the full set of 5100's, plus the 10mm rear and 1/4" front driver's side spacers - they already shipped (man, ToyTec is FAST!!!). I'll start there (probably go ahead and install the 1/4" spacer up front as well) and see where I'm at.

I'll report back next weekend or there about's when I get this stuff installed. I found a shop that will compress the front springs for me - but how hard is it if I borrow the spring compressor from AutoZone (free rental) and attempt this myself? I had a shop compress the springs on my '99 Tacoma when I swapped its front shocks, and before that I was dealing with my '87 T4R with torsion bars and leaf springs :sing:

Thanks for letting me spew my nonsense on this board :wave:

Congrats on the purchase - those struts should ride well.

It's actually not too hard since you are using your current springs. Take the current strut off the vehicle and put the spring compressor on and start tightening down. You won't have to tighten down much since the spring is already compressed a fair amount. Then remove the top hat when you see it's not under pressure anymore... then pull the shock out, slide the new 5100 in and get the bushings, washers, and top hat in order and centered and then tighten the nut up top and proceed to loosening the spring compressor... done - I say try it first... if you can't do it then take them somewhere, but I have faith you can handle it!

Don't mix the driver's and passenger springs up - they are different.

Thanks for your confidence in me :cheers: If the spring compressor cooperates, I think I'll be fine as well (fingers crossed)

Don't mix the driver's and passenger springs up - they are different.

So Toyota is already attempting to adjust for the lean from the design phase? Is there any way to get the factory driver's side springs "stretched/lengthened" to compensate for the lean w/o adding spacers? And would that be a more satisfactory way of dealing with the lean?

The "correct" way to compensate for this (to achieve a true weight balance across L/R) would seem to be moving the battery to the passenger-side in the rear cargo area :suspicious:

Alright, bumping an old thread since I did some "SEARCHING" that people are big on. Is it possible that 4wheelparts mixed the springs when doing the install? How can I check the springs to make sure they are on the correct side? Is this different spring idea also accurate for 2014's?

 

[SoCal4Run]

Alright, so I took pics of the front springs at lunch time. Looks like the passenger side is closer spaced (more wraps) than the driver's side. From what I seemed to have read earlier, this is softer, correct? So it should be on the passenger side. Please see below and let me know. Thanks.

Anyone with info on this?
