Im not sure what brand Mcgaughy is comparing their spindle to, but I know one damn thing....ground force is the same height as stock so Im gonna have to call BS on there advertising "only manfacturer os spindles that keep same steering geometry"




Heres a set of ground force spindles with stock spindles off a 2008 truck I did a drop on today.





Heres a set of new rusted MCG spindles, as you can see from the above pics the GF are powdercoated.

 

I had a ground force 3/5 kit and it was a quality kit with heavy duty parts. Worked for me. Nice truck.

 

I lost considerable turning radius with my McGaughys spindles.

 

I wanna see a belltech comparison to stock spindles

 

belltechs are hideous compared to stock.

I have belltechs on mine and they are powdercoated as well. Im wishing I went with Ground force haha

(I believe on the comparison the "competitor" spindle is a Belltech, IIRC)

 

Mcgaughy is comparing there's to Belltech not Ground Force. Ground force is clearly superior to Mcgaughy, I have used them both and Ground Force requires very little alignment adjustment whereas Mcgaughy takes almost the full amount of alignment snail travel to get the suspension corrected.
I also didn't like using a non-coated set screw with a nut on it on the Mcgaughy spindle for the top bearing fastener. Set screws are a very hard steel to bite into a shaft and are really not intended to be used for a tension loaded application subject to corrosion.

 

I am confused on this debate of lowering kits. I was under the impression the bell tech is the best lowering kits for trucks...I haven't heard anything bad about them at all. I do understand that the GF spindle is the best one out, but listening to everyone it makes me think that bell tech is garbage too. Am I mis reading these comments?

 

The spindle itself might be the ame height, but the distance from the hub assembly bolt holes to the top ball joint is shorter. if you look at the photos you can see how the top bolt hole is 2 " closer to the top ball joint. This is what effectively gives you the drop.
I think the taller spindle only contributes to alignment issues, IMO.
BTW: The spindles that Summit sells under their own brand name are Ground Force, I gather. I bought their rear shackle kit the other day and it came in a Summit box with Ground Force instructions and decals and was a few dollars cheaper.

 

This is exactly what I don't like about Mcgaughy, a 1 1/2 inch difference between A arm ball joint location is a huge deviation from the stock geometry and effects the overall handling of the vehicle through it's suspension and turning travel. Mcgaughy does this for tire tuck on extreme drops, for a 2 inch drop you don't need the tire tuck and it is really icing on the cake to keep the factory engineered A arm geometry. I have driven both the Ground Force and the Mcgaughy on a GMT 900 and you can't detect the Ground Force is on the truck when running it through full lock turns forward and reverse, with the Mcgaughys you know it is there when the turning angles are moderate.

 

yeah, the loss in turn radius is quite a bit on my truck with the mcgaughys spindle. i was hoping it wouldnt be too bad, but it is. is the ground force spindle compatable with 4 wheel drive, if it is and it doesnt loose turning radius i might switch to them. what mcgaughys claims is that the spindle is the same height as the stock one and that this keeps the stock geometry, but when i seated my upper balljoints into the mcgaughys spindle it didnt sit nearly as far as into the spindle as the stock ones, it seated just fine, but the tapered hole in the spindle is a smaller diameter and the the balljoint doesnt go in as far as the stock, about 3/4 inch up from where the stock one was, which alters the geometry because the upper arm is higher than it was at stock.

-edit, just checked the website, ground force's spindles are good for 4x4's too.
