[AJMBLAZER]

True. Was thinking suspension.

1 ton will have 3 leaf front springs. most k5s will have 2 leafers

Stock suspension sounds like

Just cut, they fit.

I have done 38x12.5s swampers on a stock blazer 11r 16s (just over 38" tall) on a stock blazer.

Did 36" swamper bias plys on my BILs and didn't even have to trim anything in the rear

Some one on here just recently put 11r16s on his crew cab

My crewcab has the 11.00r16's, but with 8" of lift. If you don't want to do some healthy trimming, stay away from anything bigger than a 35 on stock suspension.

You can get the DIY4x EZ Inch for $33 ea., adding an inch of lift to your truck at four corners for $132. So I think $100 ea. is too much.

Actually, that's $33 per axle. So you could do it for $66 on the whole truck.

but 98% the time new ubolts = $$$

and what about top plates to work with the new center pin position = $$$

u bolts should never be reused if clamped down tight then removed. thay can and will come loose i almost lost a axle this way 1 time.

Not necessarily.

Maybe for driving around on pavement...those tires would rearrange those fenders with anything more than a curb.

 

[AJMBLAZER]

Wanna bet?


Hint - stock 1 ton springs don't flex well.

mine do not rub at all. nowhere. there is only 2.5" of uptravel on the stock suspension. any bigger or wider than a 38"x12.5" would be another story.

37"x12.5" should be a breeze.

if you installed lift springs, you would need to cut the same amount of fender, unless you lowered the bumpstops. thats the problem. most people dont lower the stops.

Yah the blazer I posted got wheeled pretty hard, we had welded the rear and it was totally stock. We never did anything to the inner wheel wells, just the fender. They never rubbed at all, Thats with the 11r16

I did have a 1" zero rate in the front suspension. The tires would BARELY brush the wheel well when flexed hard. If I had located the axle forward with the zero rates I'd probably have not had to do as much trimming and there wouldn't have been any rubbing.

I have some pictures of it flexing somewhere in here.
