Mcgaughy's 2/3 lowering

[Jerzboy14]

So finally wrestled up the funds to get the hoe lowered and found the Mcgaughys 2/3 lowering kit with keys in the front and shock extenders and coils in the rear on ebay. Still having some problems with the exhaust hitting the rear axle on some bumps. Will trimming the bump stop help at all? Here is a before and after. lemme know what everyone thinks

what size rim and tire combo do you have?

[Jerzboy14]

I just purchased some new 305/40/22 Falkens for my 22s. When I push down on the rear and look underneath you see the exhaust hitting the rear axle so I took it to the guy who installed the lowering kit and he bent the pipes for me to allow for more room but I still get the clank. I didn't do anything to the bumpstops so I wanted to see if that would help

If I understand you correctly, trimming the bumpstops will make it worse until you can get more clearance on your exhaust. Maybe consider some rubber hose pieces and high temp 3m adhesive spray for the time being?

I would take a look at the bump stops, typically you are going to settle on them and need to do the free travel mod:

I don't know what else there is i could do to help the exhaust out....the guy bent the pipes to give more clearance and changed the hanger angles so that the exhaust is set up higher and i am still getting some major noise on random bumps.....is there anything i can put on the exhaust/axle that would cushion the exhaust to prevent the noise? i am not sure if that is what you suggested sorry if im just repeating

Thats' what I'm suggesting, rubber hose in between the axle and the pipe till you can get the pipes relocated. 3M high temp spray adhesive works great.

You'll still have a thud but it won't be nearly as loud. I have the same problem right now on hard bumps.

yea i dont mind a few noises because between the exhaust and the subs i probably wont hear it but those loud metal on metal clunks are pretty annoying. ill definitely look into that and try it out. thanks a lot

[PavementPounder]

i love it. thanks for putting up pics!!

More than likely, the axle is contacting the frame where the bumpstop is. This will produce a loud thumping sound. You have to do the free travel mod or add helper bags to eliminate the problem. The axle should not be in the way.

[Modded]

I don't see how the axle will be hitting the fram with jsut a 2/3 drop, thats mainly more common on 3/5 drops.
I think its just the exhaust, get the pipes out the way and trim your bumpstops and you should be good!

I had a 2/3 drop b4 my current 3/5 drop and I never had an issue with the exhaust hitting the axle.

[Modded]

Oh, well he said ith the exhaust hittinf the frame so i was just going by hin input. I have a 2/4 drop on my 07 with no problems at all!

[UWMlax15]

The 2/3 drop looks real nice on your ride. I've been up in the air about goin 3/5 or 2/3. How are your curb-hopping abilities?

[Jerzboy14]

well when i started hearing noises i laid under the truck and had my dad push the rear end down as if i was hitting a bump or something and i saw that the exhaust pipes were hitting the axle and were actually getting a little bit dented. after my guy bent the pipes and did some maneuvering to the hangers its a little better but still far from perfect......my curb hopping abilities are slightly less than stellar but still love her....

That 2/3 drop looks good!

I have a 2004 Yukon rolling on 305/35/24. If I install a 2/3 drop, will there be major issues in rubbing and turning?

Does anyone have this set up? If so, how is your experience?

I've got an 04' on 305/45/22's and run a 3/5 drop. I had to trim my liners quite a bit and still rub on full crank especially to the left but nothing major, just rubbin plastic. If you go low your gonna rub......that's just the way it is........

[titanium02]

hey jerzboy did you do the install yourself or did you have a shop do it? I was going to get mine lowered but the shop wanted $800 for it.. seemed steep to me.

Besides, rub isn't all that bad.. if someone says something about it, you just ask them if they can make that noise with their ride ;)

I did mine myself with my brother in law, it took us the better part of the day but it wasn't bad at all....certainly not worth $800 in labor even if that is with the kit thats $250-$300 labor and that is wack. I am by no means a mechanic and I thought is was pretty straight forward, just take your time.

BTW: those LED bumper lights are ill' they must be fairly new because they didn't have them last year when I ordered new bumper lights for mine. I did clear corners with LED bulbs but I will be ordering a set of smoked LEDz like yours in a few weeks. Already watching them on Ebay.....

Yeah i ordered them a few months ago while i was on deployment.. they were hard to find.. i found a set a long time ago on ebay but they vanished.. took like 2 months to find them again.

Some light up amber and white, and a few light up all white like mine. The driving lights are super bright and the parking lamps are dim untill you hit the turning signal.. then the whole thing flashes bright.

When you get them... they're a b*tch to wire correctly.. there are quite a few different configs. you can do as far as when the lights come on and which ones come on.

No doubt.....not just plug and play? Shouldn't they just plug into the appropriate corresponding plug, DRL, TURN, CORNER MARKER? What kind if wiring is there?

[titanium02]

well they do "plug n play".. but i was pickey when they came on.. and wired them with my halo's to all turn on when i use my remote start (same with my interior led's).. you have to wire the little led wires to the stock connector that you remove from the stock bulbs.. not hard but it might lite up weird on your first try..

I have an 03 denali xl on 305/35/24 with a 2/3 drop. keys in front and shock extenders and coils in the rear. it does rub. had to cut some plastics in the rear. not much. but some. and the front i cut the hell out of the plastics. now it rubs on the metal by my firewall. its not terrible. mainly when turning real hard to the left. im tubbing mine a little in the future, not necessary tho. im just anal hah. its rubbing on my windshield washer fluid tank.

as far as the install its not hard at all. hopefully your keys and everything else under your truck isnt rusted together. mine were surprisingly clean and new looking lol so it wasnt bad. 1 hour for the front. 2 for the back. but id never done it before. and had no idea what to do. make sure you keep the notch on the rear of your torsion bar facing the same direction as it was before. sounds stupid. but it makes a difference. trust me i had to fix mine. once again because ima newb. and cut your bumpstops in half in the front and rear.
