Slamming the 72

[The72]

Hi. I'm looking for all the input I can get on Slamming my truck. I'm thinking 6/8. Minimum lol. Discs up front and coils in the back. Factory 90s chevy 15 inch wheels currently.

What amount of drop spindle can fit with 15 inch wheels? I'm open to brand suggestions as well.
Will other newer models drop spindles fit as well? I will be replacing ball joint when I install new spindles so I can install whatever ball joints will fit newer model spindles. Just incase I find me some on Craigslist for cheap.

Also, what issues will I run into. Forgot the tire size but it isn't a very tall tire

How do I achieve the remaining inches. Cut factory springs or aftermarket drop springs


Now for the back end. 2 inch blocks and 6 inch drop coils is the route I'm thinking of taking. Will the frame need to be notched? And what other issues may arise.
Again open to any suggestions.

Thank you all for the input

Lol! That's good to know. Thank you.

Im also lookin for what others have done. Issues they ran into and how they solved them.
I like to see how creative people get to accomplish their goal. Like small mods. Small cuts and welds type of things.

You should take time reading thru the forum, you will find answers to all these musings.

Most won't go that low with coils anymore. May want to look into doing bags, and definitely have to c notch with that kind of drop.

5/7 about as low as practical with springs. Gets way more complicated and expensive to go lower IMO.

And staying with 15's and a short tire also a mistake. You can't tuck the front wheels in and it's hard to keep any height to the tire which I think is so important to keeping a good luck to a dropped truck.

Drop it, tuck the wheels, and fill up the wheel well!

I used CPP's stuff on my 68, 2 1/2" drop spindles 3" drop springs in front and 5"drop springs with 2"lowering blocks in the rear for a 5 1/2, 7" drop. I also used their C Notch kit. Running 15" Rallys, 8's rear, 6 1/2's front on 275/60's and 225/70's. I purchased CPP's Grand Slam kit which gave me every thing needed for the change over. I'm very happy with the results and don't have a problem with bottoming out or tire rub but you've got to be careful driving. Oh and I used a 71 rear end for the 5 lug bolt pattern.

Thanks guys 5/7 isn't too far from 6/8 I might be able to live with that, til I get the itch to go lower lol

RodnRudy, you mention you have to be careful when driving that low. Is it mostly the front end or the back end that you have to be careful with? I ask because I can live with 5.5 drop in front but I know I might want to squeeze another inch from the back haha. What I might do is get 6" drop coils and get 1" blocks to replace the 2" blocks incase it's too low or I don't like the stance.

Thanks to everyone who replied to this thread.

Thanks to everyone who has responded to this thread. I've slightly changed directions on the back end. I think I will bag the back end so I can go realy low but air up incase I have to load it up. Can anyone recommend a trac bar? I'm looking at cpp they have an adjustable and a deluxe (long) version. I assumed the longer version would be better to keep everything center through the suspension travel but a review on summit says not good for bagged trucks..

Thanks again for any help.
