Offset backspacing question

[07teebeeLT]

just want to clarify something. need 4.5" of backspacing to clear UCA. So factory wheels (6inch backspacing) need 1.5 in spacers. Fuel hostages in 17X9 with -12 offset will work without spacers. also assuming im using those fuel wheels whats max tire size with just 1/2" front spacers

 

[HARDTRAILZ]

What's fuel backspacing?

 

[07teebeeLT]

think it works out to 4.5. thats wehre i get a little confused i guess. 9 inch wide wheel with 0 offset should be 4.5 in backspace no? but by the charts its with -12 offset that gives a 4.5 backspace

 

[HARDTRAILZ]

Depends on wheel. They are not necessarily related. Material thickness n such.

If they are 4.5, your first question is answered.

The largess tire with or without cutting/trimming?

I had to trim to fit a 265 70 17 w a 2.5 lift but others have fit them with less.

 

[HARDTRAILZ]

Other issue...

Can you get those in a 6x5? You may need adaptors...

 

[07teebeeLT]

good to go in 6X5 (one of the few wheels that are). i only ask biggest tire size with just spacers because thinking the order of things

1) 1/2inch front spacer -> new wheels -> bigger tires ->lift (hoping to squeeze tires on prelift and maybe stay on the road till the lifts on0 and skip spacers all together

2) 1/2inch front spacer -> lift -> spacer and tires -> wheels down the road (maybe resell spacers)

Lift - $455 (bds) + $800 wheels + $800 tires - $2055. Or can skip the wheels for now do spacers and save $600. UGH decisions decisions

Forget BDS and save $300 using MarkMC

 

[07teebeeLT]

valid point

Forget BDS and save $300 using MarkMC

i'm running Mark MC's 3" front lift, 1.5" spacers and oem trailblazer wheels w/ 265-70-17.
no cutting or rubbing ( but close on fender)

 

[Sparky]

I'm on the 2.5" lift (should have done 3" lift since I ended up needing new mounts anyway so any "savings" were now gone) and had to do a very slight trim on the corner of the bumper cover with stock wheels, 1.5" spacers, and 265/75/16

 

[07teebeeLT]

any chance of fitting 255/75R17 s with 3" markmc? little taller 32.1 but narrower by .5"

 

[HARDTRAILZ]

Yes. But i would not on 9 inch rim. Tire too skinny to look right.

Mark has new budget 3 inch lift. Tell him I sent ya!

 

[07teebeeLT]

will do, so 275/70R17 prob a better option

 

[Sparky]

What's the difference?

 

[HARDTRAILZ]

He self producing.

 

[07teebeeLT]

looks like i might be ordering a 3 inch lift and spacers when my bonus comes in

 

[markmc]

He self producing.

Correct.
i now have control of quality, inventory and the ability to bring lower priced products to my customers.
still pride myself in the customer service area.
You can hit me up any time for help, even if you have another vendors product.

 

[07teebeeLT]

thanks mark. What would you say are the deciding factors between the new 3inch lift and the other version?

 

[Sparky]

The 3 inch replaces the upper mount entirely, while the 2.5 just fits inside the upper mount. Since you'll likely need new mounts regardless, just get the 3 inch. Stronger and better than the 2.5. I wish I did.

 

[07teebeeLT]

no i mean the two different 3 inch lifts

Mark's profession involves aluminum casting (and probably a lot of other stuff I have no idea about). Front spacers used to be machined by an outside vendor, and machining is extra precise in dimensions this part doesn't need, so it was burdened with unnecessary cost and sharing the profit with the outside machinist. Mark now has his own backyard foundry and can make them himself, and he's passing on those savings to the community by lowering the price of this kit. (Hope I've got this right, Mark)

 

[07teebeeLT]

got it so..

Black kit = cast parts cheaper but slightly weaker
Silver kit + machined parts, more expensive but slightly stronger

 

[The_Roadie]

I'd guess the safety margin in those spacers to be about 10-to-1 overkill, so if the cast parts are only 9-to-1 overkill, I would not use worry-about-them-breaking as a deciding factor which kit to choose. Offroaders can't afford ANY preventable trail failures, even if some of us are excessively frugal. (Frugal meaning cheap-ass....)

 

[07teebeeLT]

lol thats what i was thinking

 

[HARDTRAILZ]

I know from experience Mark gets his products field tested before offering them to the public.

Hit the nail on the head there Bill. Thanks!
Couldnt have explained it any better.
