I have been looking for a 4/6 drop kit for my 02 reg cab GMC, I am really leaning towards a mcgaughys kit but I cam across this kit
99-06 Silverado/Sierra 4/6 Lowering Kit
Does anyone have any experience with this kit or familiar with it at all?

 

I actually bought my 4/6 for my RCSB Sierra from them 2 months ago.
Really nice people over the phone and helpful. I actually placed my order online, 1 hour later I got a phone call to confirm I was getting the correct parts. I went with they're "cheaper" package (the link you posted) which is actually all belltech parts. C-notch, spindles, flip kit, belltech street erformance shocks, were all belltech name brand. I also retained FULL steering angle.

Worked for me

 

all good stuff and with bell tech spindles you keep your turning radius

 

Oh cool thats good to know that the parts are name brand belltech parts and that I can keep my factory turning radius. Do I need 17"+ wheels to use the belltech spindles or can I use my factory 16s for now?

Thanks for the coupon code addy, also do you have any pictures?

Edit: I saw the picture of the spindle again and saw where I need 17in and up wheels. Also is it true the belltech spindles push the tires out a little more than stock, as long as I pick the right tire size I should be fine though correct.

 

Here are pics of mine. Sorry, shitty pics but its all I got for now.
BTW I have 18" wheels and it barely fits. Got about 1/4" space between rim and SAWN OFF lower ball joint stud.

 

Truck looks real good Addy. I guess it will be a good idea to find some 20s before I get the drop.

 

I prefer timsuspension over them for sure, bought from both, Tim will take time out to answer any and all questions.

Also, Mcg has better geometry than BT, won many awards for it. I would go with MCG

 

Thanks for the additional info. I have been doing a few searches over the past few days trying to compare belltech and mcgaughys. What had me interested in the belltech kit was keeping my turning radius but I guess there is a mod to fix that with the mcg spindles. Does anyone no if I can do a 4/6 drop with the 16+ spindles and keep my 255/70 16s? I ask because if I can drop it before I invest in wheels that would be awesome because I wont have to wait as long lol.

 

I did some quick serching and I found I can use my tires with a 4/6 drop. I guess I will be going with a Mcgaughys 16+ kit and use monroe shocks for now, I found the proper part numbers and have them saved.
