I've been looking for a while but haven't found this question addressed anywhere:

Part 1:
From what I know, the AS 1.5" is conservatively named and actually yields about 2" of lift.
Does this mean that the 2" AS kit actually yields 2.5" of lift?

Part 2:
I've read that at 2.5"+ of lift, the suspension components are stressed and will wear sooner.
SO If the 2" AS does yield 2.5" of lift, does this mean that I should stay away from the 2" kit and stick with the 1.5" so as to put less stress on the suspension?


Hopefully this isn't worded too confusing. Essentially my issue is that the AutoSpring kits seems to be conservatively named/rated, and I don't want to buy a so-called 2" kit if it is actually 2.5"+ and going to mess with the suspension angles.

The wheels I have purchased are 20x9 KMC Addicts +18 and tires are 275/65/20.

 

I had a 2" AS on my 2011 and only got 2" of lift from it.

 

Hey NASSSTY did you have any rear lift, you Ran 295/60r20 Trail Grappler, any Rubbing? I have the same truck as your last one Scab FX4 and loved that Stance you had, do you think there would be rubbing with my Mudflaps. I'm trying to find OEM gun metal 20's

 

I have installed -5- of the AS kits on my and my buddy's last 5 150's. Regular cabs, super cabs, crew cabs. Honestly, and I don't know why, but they never work out the same way twice. I just did a a 2.5 on my s.crew and got 2.8". On my last s.cab, it was nearly 3. I will tell you this, that I put 100k on that truck, and had not one issue with the front end. No wheel bearings, no shafts, or balljoints or anything. Had 100k warranty too. New owner is still driving it. Obviously a larger spacer puts more stress through things, I'm just not sure that it's enough to say so.

 

No rear lift, just the spacers in the front. I didn't have any rubbing, but I've read about others that had a slight rub on the UCAs when turned to full lock. Not sure why some do and some don't. Probably because not all trucks have the same amount of rake when stock so they don't all end up with the same angles after leveling?? I'm not sure about the mud flaps? I haven't ran them since I had my 97.

 

1st of all, ALOT of ppl get confused on spacers. A 2" spacer may be like "1.something" measured alone, but after the suspension and drive angles, it nets 2" of lift. U could technically be a tad higher than advertised. Measure center of wheel to fender before and after. Either way, the 1.5 and 2" will both work for a 275/65/20. Choose the 2" unless u tow or haul. Then u may want less to offset the sag.

 

The 1.5" autospring spacer is actually 1.25" thick. If you compare with other companies kits you will find that most of their 2" kits are also 1.25" thick spacers. I looked into this before deciding on the 1.5" AS. It gave me just a little under 2" of lift, and still have rake. I wished I would of went higher to make it perfectly level. I just ordered the Boss coilovers so my 1.5 AS will be coming off.

 

Did this make it level?

 

No I had 2.5" of rake (stock) and I wanted a slight bit of rake. I ended up with .5" of rake, pretty much got what I was hoping for.

 

Our 2" level spacer measures just under 1 3/8" and our 2.5" spacer measures 1 5/8".
