More stupid questions
 

Okay here goes....My 72 blazer is getting close to being finished with the patch work (floor pans, rockers, windshield frame, b pillars) i noticed that there is a little bit of rust on the rt side wheel house tub lip...(where it bolts to the bed) Are truck and blazer wheel house tubs the same? Question 2 i do want to beef up the suspension a little.. Nothing drastic...besides the obvious answer (2 inches) whats the diffrence between a 2" and 4 " lift? Im not sure if i got a 4" lift that it would fit in the garage..question 3...Anyone know the exact measurement of how tall a blazer with a 4" lift is?

First - I believe the wheel house is the same on Blazers and Fleetside PU (subs are different).

Second - Why do you want a lift & what size tires are you going to run? Lifts don't all measure the same from manufacture to manufacturer. The same holds true for tires - some 35's are only 34" tall, others are 35" tall.

I have approx a 4" lift (installed by a PO) and I'm running tires that are 31.5" tall. My truck fits in the garage with about 1.5" to spare. The Blazer I had before this one had 6" of lift with 35's and it was about 4" too tall to fit in the garage. My current Blazer is a much smoother and truer tracking ride. The one with the big tires had a lot of bump-steer and was a challenge to drive at freeway speeds.

Bouncy...I want a lift for a little more ground clearance...not going to be doing major off roading....i will probably want 31.5 or 33 tires...from the floor lip of my garage to the door is 76"...that 1.5" you have to spare, is that with the top off?

Dirt1972 - The upper portion of the Blazer and pickup wheel arches are the same (from mid body line on up). But the radius of the front lower Blazer wheel arch is different than pickups. The Blazer is squared off whereas the pickups have a rounded edge.

With the top off, it's more like 3-4". I park it in the garage every day without any problems. We do not have a tall garage - the house is a tri-level with bedrooms over the garage.

I'll send pics....thanks bouncy on the measurement info...I'm hoping a 4" will fit in the garage..i'm about a month away (hopefully) from really crossing that bridge...wonder why they dont make a 3"...

You should be able to fit 33's under stock ride height. I'm running 31's with tons of room to spare.

Re: More stupid questions
 

You can, I run 33's with stock ride height. Still enough room around the tires, even with the mild off roading I do I've never had an issue. Just the tires alone gave me all the ground clearance I'll ever need, and it's still not terrible to climb in everyday :lol:

Be careful with 33s on a stock blazer suspension. I tried this and if the wheels were turned hard over a bump they did rub. It depends on how old and worn the suspension is. I have since put a 2 1/2 inch tuff country all spring lift and the 33s look good at that height and it will not rub anymore. I have a soft top on mine and it still fits in the garage with a little to spare.

By the way, the pic in my avatar is the truck before the lift. stock height with 33s that really measure 33 inches.

Re: More stupid questions
 

Been this way for years. Full lock turns off roading over some interesting obstacles :lol: Never had any issues. Maybe my stock suspension is still taut.
Could be that I run the 10.5 wide tires too. Maybe the 12.5's are giving others an issue??
