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?

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

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.

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!
