2.5” lift kit

Looking at buying a used set of toytec boss coil overs. What is the max height of lift (2.5” ?) before having to upgrade uca? It’s for a 2015 Tacoma trd sport

 

Somewhere around 2.75” my stock UCAs would rub the coils under normal driving. I’d say 2.5” is the max without getting UCAs. Many people get aftermarket uca with a 2” lift as well though.

 

Ok great thanks
Will my caster alignment be fine at 2.5”?

 

What size tire are you planning on running?

 

Odd response to a question about caster. Good question, just odd is all. So do you know if the caster will be ok with a 2.5" lift? I do not as I planned on and did use aftermarket UCA's anyway.

 

Actually it’s not. If he’s planning running a let’s say a 285/70/17 2.5 caster will not clear the back of the fender and may even rub the body mount. If he’s planning on running something close to 31.5 it probably would be fine. Personally I like that higher caster tightens up steering response.

 

I’m looking at putting 18” rims on what tire size is recommended with stock uca?

 

That's interesting. Couldn't a person just use a skinnier tire or does the width of the tire create clearence issues?

 

Sure. Not everyone likes skinny tires. But yes you could run a skinny tall tire.

 

Cool. A wider tire must require more cutting then?

 

Yes sir

 

Because a wider tire goes further back (or forward depending on which tire and which direction of turn) than a skinnier tire, correct?

 

Is a 2” top mount spacer in the front and 1” block in rear really going to effect the ride quality, it’s not a pre load spacer . Truck is mostly on the highway rarely off road the odd time

 

Is a 2" spacer a 2" lift spacer or a 2" thick spacer? Because a 2" thick spacer will lift the truck 4".

A spacer by itself will adversely affect the ride quality. Potholes and speed bumps will make the truck feel like it's jumping around a little on bumps. The ride will be harsher. The upper control arm's ball joint doesn't have enough down travel. The fix is a pair of aftermarket upper control arm's (UCA's).

My truck has 3" lift spacers, aftermarket high caster upper control arms, stock struts, and I think it rides fantastic on the street.

If you decide to use front spacers do not buy the type with studs, you want the type with bolts. I read the warning elsewhere on here, I ignored the warning, and I regretted it.

Don't forget about the bump stops. By installing spacers the front struts position is moved and requires moving the bump stop down. I read somewhere that someone used a rear bump stop off of a Chevy truck in the Tacomas stock bump stop location. If you don't take care of the bump stop eventually you will break a front strut and you will not be happy.

I removed the front sway bar which made it ride better. The steering is loose feeling and the body sways a bit in turns. I think I like that part more than the killer ride quality it has.

So you also wrote a 1" rear block. That's exactly what I bought. The one I bought was on eBay. The block is shaped like a wedge. It was advertised as a 1" lift. It was amusing to me because in the center of the block where the axle pin is measured 1 1/4". So I measured the truck. The blocks lifted the truck exactly 1 1/4". Another note about the blocks I used the hole for the leaf springs pin was way too big. I thought about it and realized if the two sides don't match they won't be lifted exactly equally, because of the wedge shape. So on the right block I moved it as far back as it would go and on the left side I shoved the block all if the way forward (Taco lean). Then I got tired and called it done. Lol. My truck has rear leaf springs with 2 leafs and a overload leaf. It should be 3 + 1. The truck has easily noticeable rear axle wrap. I would expect a spring with 3 leafs to have less axle wrap but I doubt 3 leafs would correct the problem entirely. The ride quality from the back setup is fantastic. I don't have the paper allotted right now for truck parts so axle wrap it is.

Definitely noting my truck ain't built for off road and would be terrible at it, so OP you've been forewarned!
