Thickness of Daystar front spacer?

I recently ordered and installed what I thought was the Daystar Comfort Ride
1" Budget Boost (KT09117BK) for my '04.

After measuring about 2" of lift after installation, I got a little curious. I think I may have actually received the Daystar Comfort Ride 2.5" Leveling Kit (KT09116BK).

My spacer looks like the one from the 2.5" kit, and it measures exactly 1" thickness. Anybody know the thickness of the spacers for these two kits? I can't find the info on dimensions anywhere.

A knoxville guy! Good to see another one. If it measures 1" thick it's a budget boost! Or I would think! I have a budget boost as well, I can go look.

That would be awesome if you could. From what I've read, a 1" spacer should give about 2" of lift on the front, which is a little confusing to me because of the way Daystar names their products. Should the budget boost lift 1", or should it be a 1" thick spacer? The other thing that confuses me is that my spacer and the bolts that came with it look exactly like the parts from the 2.5/1.5 kit. What does your spacer look like?

The names daystar lists are for the lift heights. the 2.5/1.5 kit lifts the vehicle 2.5 inches in the front and 1.5 inches in the rear. the budget boost 1" kit lifts the vehicle 1" in the front

It is a little confusing, and not sure why Daystar did that either. The 1" budget boost does lift 2" I will look tonight and let you know. Did you have to disassemble the strut to install the spacer? Question, do you actually live in Maryville? Work at Advance?

Actually it seems to me from mine and many others, the budget boost lifts 2" and is 1" thick. But I guess its supposed to be 1" net

i helped a friend install one once and it measured a little larger than 3/4 of an inch thick, he got about an inch and a half over stock all installed.
 
I didn't have to disassemble the strut. And I live in Northeast Knox (Gibbs area).

I know for sure my spacer was exactly 1" thick, so I'm guessing maybe it was just an older version of the 1" budget boost that looks like the spacer from the 2.5" leveling kit.

The reason I'm wondering in the first place is that I just bought 1.5" rear spacers and I'm thinking I'll have to trim them down to 1" to keep the rear from looking too high. On that topic, anybody know of someone who has done this?

If you didn't have to disassemble, then you have the 2.5" Atleast from my knowledge.

I think you will be fine either way and not have to trim down.

I think this was FJ springs, and budget front with 1.5" rear http://www.toyota-4runner.org/4th-gen-t4rs/99069-weekend-mods-plasti-dip-spray-paint.html
 
FYI:Calculate lift for a given spacer thickness

Saw other posts with empirical data but no explanation, so with my background I thought I would provide a reason and a simple equation (eqn). for calculating final lift for a given spacer thickness.

FYI: the lower arm is bound by the ground when not moving but when articulating it puts its energy into the suspension where R= dS/Dw explained below, but we only need to consider the upper A-arm for spacer thickness vs chassis lift.

1. Measure from the upper pivot ball joint to the swing arm on the upper A-arm, this is b2 ( base length for triangle 2).

2. Measure along the same line from upper pivot ball joint to where the shock center bisects the line determined from #1 above. This will be the distance, b1, (base length for triangle 1).

3. Based on the geometry of Similar Right Triangles and a static or non articulating suspension( freeway is not enough articulation so aprox. static) then the equation is as follows: b1/h1 = b2/h2. h1 and h2 will be the heights at the shock and chassis ( or swing arm position).

Example: Static or parked on flat road calculate lift for a 1 inch top plate spacer.

For a 2017 5th gen 4runner approximately measured when static or stopped and/or smooth highway suspension oscillations which are insignificant:

b1 = 5", b2 = 8", h1= 1 for a 1" spacer;

and h2 = b2/b1 x h1,

Plugging in the numbers:

h2 = 8/5 x 1 = 1.6"

For 1" spacer we get 1.6" of lift
For a 1.25" spacer we get 2" of lift
For a 1.5” spacer we get 2.4” of lift; You can measure b1 or b2 length for any similar suspension.

Note: For articulation then need motion ratio, R = dS/dW; S=suspension travel for a given amount of W=wheel travel; we can say d(h1) is approximately equal to dS ; then dh1=RdW; substituting this relationship into b1/h1=b2/h2 and solving for h2 we get the following:

d(h2)=b2/b1 x R x dW

integrating :

∆ h2 =R b2/b1 ∫(0,w)dW or ∆h2=Rxb2/b1x∆W

A dynamic oscillation off road or racing, suspension articulating significantly energy into chassis, chassis popping up and down, this is where spring rate comes into effect with shock dampening.

Got it. :keyboard:
