Lowering a 74 GMC 1500

I want to lower my 74 GMC 1500 pickup 2-3" in the front. What would you use? Spindles or lowering lower control arms? The're about the same money So i don't know the pros and cons of each. Thanks, Todd.

Drop Spindles, but you may want to go with a 15 X 6.5 van wheel to clear the rail on the edge of the control arm.I am planning on building a 73-74 chevy, I am thinking of lowering it 4.5/5 but may go with 3/5. If your planning on keeping your stock grille,but it has faded,ceck out my other threads for how to redo them. Do you have any pics of the truck?

I don't have any pics yet, it's a stock short bed fleet side with it's original 454 auto. Any idea how many 74 GMC 454 shortbed fleetsides were made? It's a Sierra Grande? I've been trying to look it up for a couple of days with no answers.
Thanks, Todd.

Definitely stick with the spindles. Drop arms are junk, especially if they are made by DJM.

But if you want tube arms, AirRideTech (ART), or CPP is the way to go.

You can also box your control arms. Heres the 1973-1974 grille that I redid a while back
Here's the thread

3 inch drop spindles
4 inch rear hangars and shackles

one bed support crossmember will need to be trimmed for shackle clearance
8" stock wheels are pushing it for front clearance to the lower A-arms.

I have a set of 8" ralleys that rub when turning
And I have a set of 8" standard wheels that do not---but wheelweights to get marred in a hard turn. Have not knocked a weight off of the standard wheel yet tho. (will be putting them back on soon)

My truck was lowered in 1990 (79 C-10 LWB 454/4-spd) and has not given me any issues whatsoever on the modifications (other than driveshaft angle----I have a 2-piece shaft that required trimming the carrier support to raise the center of the shaft.
What used to be a u-joint every 3-months----became never changed one again )

about 250,000 miles since this dropping and I do not have any tire issues at all.

Got everything I needed from Bell Tech------Are they still around????

I guess i'm going to go 3" front and 4" rear, although i've seen with a 4/6 drop and it looked great. Also it looks like i'll use a 7" wheel in front with an offset to clear control arms and 10" wheel out back if i have enough room. Can't wait!
