why six lug!??!?!

just curious.....i see a ton of five lug trucks on this board and a ton of 6 lug trucks as well.....personally i like 5 lug, you have many more rim options and all the cool designs and clasic looks are in five lug.....just wondering why some trucks are 5 lug and some are 6....would you choose to buy six lug back in those days or what....mine is 6 i have a 1500......my friend has his truck it is the sae year.....69....and his is 5 lug....WHY? just curious

Well 67 - 70 Chevy/GMC trucks had Drumbrakes with 6 Lug Wheels all around but in 71 our trucks had Disc Brake Option which were 5 lug. Your truck must have Drum Brakes and your Friends 69 must have been upgraded to Disc along with a 5 Lug Rear..

If I have my option of buying an older truck, I would choose 5 Lug myself but not too many people know that you can upgrade your 6 lug drum brakes to 5 lug by just doing a 71 - 72 Rear End and 71 - 87 Front Suspension or even the Spindles, Rotors, Calipers and all mounting hardware.. This is what I am doing to my 68 after I cut my frame down !

well, from what i've heard and observed, 67-68 had 6 lug. all fours were drum brakes. When 69-72 it went to front discs, 5 lug all the way around. I think. But the other day, I saw a truck after 68, because it had a later front end. But it has 6 lugs. Did some of them come with 6 lug in 69? Anybody know?

The first 5 lugs were the disc brakes in 1971 all before were 6 lug
drums.

You can convert early drums to 6 lug disc's(using later spindles) if you want to keep the same rear and only carry one spare tire.

Correct me if I am Wrong on this.

Actually, 4WD 1/2 tons kept 6 lug through 2003, and starting in '99, 2WDs are 6 lug again also.

Okay come on man, don't laugh at me. I'm just now getting into this hobby. The only thing I've learned is what I've overheard, watched, or learned by my own little tinkering. It wouldn't be very nice to laugh at someone like me would it, 15 years old, young, dumb, and trying to learn. Dont laugh at Me

I guess I've got tunnel vision about Chevy trucks. I don't know a thing about anything newer than a '72.

I know the bolt pattern is the same, the offset I am not sure about but it SHOULD work.

The bolt pattern is 6 on 5 1/2" for all years. In 1988, with the IFS trucks, the backspacing was changed from ~3 1/2" ('87 and older) to ~5 1/2" ("88 and newer). The center hole is also a different size, I think.

Hey muscletrucks, ask away. Don't worry about those that aren't willing or want to help. Most here will. Good luck with your pickup.

I got a chance to look at my brother's truck a week ago, and the offset is VERY different: I know they wouldn't work on my drum brakes.

I have 6 lug; I intend to KEEP my six lugs. Of course, I prefer the stock wheels. . . . If I decide to change them, the 4x4 suppliers have a pretty good selection.
