Drop Spindle with 15" wheels ?
Hello all, new to 89-98 - I've had 3 99-06 and am pretty familiar with those.
ok so let me try and be concise here : I know that with the 99-06 when you are running a drop spindle your wheel needs to be 17" or bigger for clearance from the lower ball joint, or a 16" wheel will work if you run a ball joint spacer. So, with these 89-98 trucks is it the same deal? I seem to have seen a few trucks when researching that run drop spindles with stock 15" wheels, which is what I want to do. So is there a certain manufacturers spindle that needs to be run? I've used Mcgaughys on 2 of my 99+ trucks and have nothing but praise for them. I have a 94 Silverado shortbed 2wd with 454ss wheels. Thanks! |

Correct, a 15" wheel won't clear the lower control arm with a dropped spindle. You can clearance the lower control arm and make it work however. You have to grind out part of the lower control arm, there are some posts out there with details I am sure.

My 17" rims needed alot of clearancing to run tiny 2" spindles, I'd think you would need backspacing to be perfect to make 15"s work?
My 78 and my old 79 both ran 3" spindles with 15"s no problems or grinding. Ahhh the good old days |

BellTech spindles push the front wheel track width out slightly to try and compensate and clear the control arm with smaller wheels, but then you can run into tire rubbing issues with your fenders if you're too low and I just think it looks bad with the wider front track.
Here's a picture (not mine) showing how to trim the "rain gutter" on the control arms to give clearance. |

Thanks for the replies folks!

I wonder if that's a 15" wheel? That doesn't seem like too big of a deal grinding/cutting the lower arm, I would just worry at some point taking out too much material and loosing the integrity of the arm. But if that's a 15" wheel in that pic then it'd be ok, I think. I wonder if that's one of those compensating bell tech spindles? So I wonder if I got a mcgaughy spindle if I'd have to clear out even more material, 'cause I surely wouldn't want to clear much more than in that pic. |

No, those aren't BellTech spindles. They're DJM, I believe. DJM used to sell plates that you could weld onto the bottom of your control arms to box them in after trimming the lip off, but it's really more of a placebo. I know guys who have run trimmed arms without boxing them in for years without a lick of trouble from it, so you'll be fine. |

That should settle it then for me, spindles are a-go with a little cutting/grinding. Thanks! |

Dropped spindles (Belltech) & 15" Ralleys.....

Re: Drop Spindle with 15" wheels ?
I had a 90 that I lowered with spindles and had stock 8" rally's on it. It was 20 years ago, so don't remember all the details. But don't recall having to clearance anything.....

I now have a '97 Tahoe with DJM 2" drop spindles. I bought 15" Wheel Vintiques smoothie wheels & did custom 4.5" backspacing. Once I trimmed the lower control arms, no issues with them either. However, I did have to grind down my calipers a bit to prevent rubbing, because I got a little too much backspacing. |
