i"m putting my ford keys on this weekend i'm wondering how much space to leave between the stopper and the upper control arm? And will 285/75/16 tires work on 2001 1500 GMC 4X4? Thanks for any info

 

i have 285/75/16 on a stock height 2003 1/2 ton chevy.
they rub very little but i plan on also using the ford keys in the NEAR future!
here is a pic of my truck

 

I ran 285s with no problems on my 99. I used the ford keys for a while, but also just raised the torsion bars when not running the ford keys. Its the same result, but the ford keys allow you to turn them up even more. Ride quality went to hell with the ford keys installed. Crank the torsion bars before buying the keys. If it works enough for you, then save your $$$ and time by skipping the ford keys.

 

What is the part number on those keys? What model year(s) do they come off of?

 

I'm fuzzy on the whole key thing, I understand that the new ones are for raising the front up, do they have ones that will keep the ride/handling the same, if you wanna lower the front, just maybe an 1" or so?

 

the keys are off a 2000 f150 part # XL3Z5B328CA.thanks for the tire info.i would back off the torison bar thats there if you just want to go down 1"

 

i put in the ford keys and it tore up my torsion bar bracket... ride went to hell and just pulled them out raised up the bars i will go with a 3 or 6 inch lift in the next year or two at least you will have some sort of suspension... im just nervous i would break something

 

Belltech makes keys that allow you to go down 2.5-3", pretty low compared to a stock height 4 buh 4.
