Lowering an 84 GMC.
My son wants to lower his 84 GMC I got him for Christmas last year. So that's this year's Christmas present. Just wants to see what kits people are using.on these trucks. Looking for a 3" 4" static drop.

Re: Lowering an 84 GMC.
I prefer BellTech or McGaughys. With a 3/4 you could do 2" spindles and 1" coils on the front and shackles and hangers on the rear. Although I recommend 2 1/2" spindles, 2' springs and a rear flip kit giving you a 4.5/6 drop.

Re: Lowering an 84 GMC.
I just did my sons truck....I used Western Chassis components.
IF it were me and being a young mans daily driver, I would do a 3.5" front and 5" rear. Its a good daily driver height, the 4.5/6 looks bad ass but I didnt want to notch on the frame. 2.5" drop spindles and 1" drop coils for the front. I would do a 5" flip kit in the rear, its easier than hangers and you shouldn't have to notch the frame. Heres my sons 3.5/5 ![]() ![]() Last edited by Rangerman; 11-19-2015 at 10:05 PM. |

Re: Lowering an 84 GMC.
I have used Bell Tech products on the last 3 trucks that I have lowered and have been very satisfied with the results. I have had very little experience with any of the other brands, so can't comment on that.
As far as how low, my current set up is 3" Bell Tech spindle and 2" Eibach coils (from way back when) up front, and a Bell Tech flip in the back (with C-notch). I used Bell Tech Nitro Drop shocks all the way around with no shock extenders (I know, I know...). With only a front sway bar, it corners better than stock and the ride is a little harsh, but I like it...it's a truck after all! BTW, I am using 17" wheels front and back with a 28" tall tire in front and 30" tire in the rear. Good Luck!!! |

Re: Lowering an 84 GMC.
The boy wants to keep his rally wheels so what ever we do will clear with a 15x8 rally. He doesn't want it really low and neither do I. He is just getting his licence and isn't very exprienced. I am sure he will make mistakes and I would rather not have the truck slammed the first time he pulls into a ditch or such. I will post pics of his truck as it is now.

The rally wheels may fit, you will probably have to remove a little metal on the lower control arms to alleviate any possible grinding. If he messes up a inch or two lower probably wont matter. Lowering is like building a shop, you will wish you built bigger and you will wish you went lower. Trust me,lol. |

In the rear if you use a shackle its cheap, but be aware that you may need to notch the bed brace for clearance. You can do a flip kit, just make sure you get shock extenders to regain your shock travel and proper angle. Take a look in the Suspension Forum for lots of pics and coverage.

Re: Lowering an 84 GMC.
I know how it is. My old truck sits as low as I can go and not notch it. When I cage it it will be backhalfed and slammed the rest of the way.
As for air ride that not an option. I don't want 2 am phone calls that he busted a bag and needs to co.e get him with the trailor. |

Re: Lowering an 84 GMC.
I put 2.5" spidles and 2" coils on the front of mine, with a flip kit in the back.
If i had to do it again, I would have used 1" front springs, or just cut a coil off the stock springs. My stock size front tires bump into the inner fenders if I get carried away over railroad tracks. It also has a rake...3.5" in front, and a flip kit in the rear would have my truck level. I used summit racing spindles up front (I forget the brand, but it was a decent quality re-packaged spindle. i used DJM springs in the front... they were too soft for my taste from day 1. i also used a DJM kit in the back, and the shock extenders didn't fit right, and other people on the site have pointed out that DJM flip bracket is kind of cheesy. When you flip it, most kits will move your rear axle back, so the drive shaft doesn't bottom out...but it looks goofy with the rear wheel not centered in the opening. Fortunately when I swapped my 3 on the tree for a T5, i needed a new driveshaft, so I drilled the flip brackets right in the center, and bought a driveshaft to match. |

Re: Lowering an 84 GMC.
I agree on staying away from the DJM flip kit. The quality didn't seem very good so I ended up going with a 5" western chassis flip kit. The DJM kit is now sitting on the spare parts bin. I did use the shock extenders from the DJM kit which as mentioned before don't fit very well, but I made them work.
For the front I did use DJM 3" spindles which surprisingly were actually good quality in my opinion. The tolerance for the caliper mounting was so tight that the caliper wouldn't go on if not perfectly aligned. I also cut 1 coil off the front stock springs. The only clearance issues I had was with the inner wheel weights on my aftermarket 15" rims. I was using sticky weights and wouldn't clear the caliper mount. Regular snap in weights worked fine.
