1 front 2 rear drop
Just got my 72 c10 back on all 4s. I replaced steering linkage, ball joints, brakes, shocks, and springs. The truck sat pretty high when I got it. I plan to use it as a fair weather daily driver and it needs to be capable of pulling an open trailer with around 5-6k. I went with the smallest drop springs I could find. 1 for front and 2 for rear. When I got the front springs out, I found a 1 rubber spacer that I did away with. So the front is 2 lower than when I got it.
I was surprised when I got it down on the ground. The drop did more than I expected, but it looks really good. I now have 3 3/4 gap from tire to fender in the front. In the rear there is 4 1/4 gap. The tires on now are 255/60/15 (27) front and 275/60/15 (28) in the rear. Im going to put on 31/10.50-15s all around. That will use up 2 more gap in the front and 1 1/2 more in the rear. So it should be in the 2 to 2 1/2 range after new tires. I think that will look great. Im adding front and rear sway bars. Im also adding front and rear air bags, the kind that go inside the coil springs. That should keep things from rubbing when there is tongue weight. |

Re: 1 front 2 rear drop
I'm not sure I understand why you lowered the rear more than the front when the idea with minimal drop is to allow for hauling and towing. These trucks run 2" higher in the rear from factory. That's why the first drop kits were 4/6, to create a car-like level ride vs the pre-sprung rear stance that is typical for allowing for the duties people bought trucks for originally. You did minimal drop so it will be fine.
My chassis has a 4/6 drop installed. I bought it that way. That doesn't allow for much hauling/towing. I'm considering either 4" rear springs (I also like the rake) or bags in place of springs so I can go level, rack, haul or cruise softly. I want a cool looking truck I can use the bed or tow with, too

Re: 1 front 2 rear drop
I'm curious to see yours with the 31s installed. I have them on mine with factory 84 C10 crossmember and springs on the front and original rears. I like the stance now but was wondering what a slight drop would look like too.

I think your truck may have been one of the pictures I looked at when trying to decide what tire size to get. 31s look good on c10😉 |

My thought was that I would go with the 1 & 2 drop springs and see how it looked with 31 tires. If it was too high on either end, I could drop spindle or drop block from there. I wasnt expecting to find the 1 rubber spacers up front. From the looks of things so far, spindles and drop blocks arent necessary. From the reading I did on here, it sounded like I wouldnt run into issues towing with the spring sizes I chose. I always planned on using air bags with the springs, so I think its gonna work out nicely. The vast majority of driving will be around town, so I want it to look good. But I need it to be a truck when called upon. If it turns out that I need to switch out springs to meet the end goal, I will. |

Re: 1 front 2 rear drop
Use caution when picking a rear sway bar.
Some are untested and one in particular caused a very dangerous back and forth sway on my truck. Bars, that attach to the differential, not the trailing arms are, in my opinion, the better choice. They also mimic the factory rear sway bars on later trucks. |

Did it go away with the sway bar off? Did you go to the rear end mounted style? |

Re: 1 front 2 rear drop
Has anyone got a 2 inch drop spring laying around and could give the measurement from top to bottom I got a set and there 12 1/4 tall.
Does anyone sell a 2 1/2 drop spring? Thanks,

Re: 1 front 2 rear drop
Got to admit, Im not sure where rear sway bar mounts. The directions have you mounting the vertical uprights where the frame curves upward. That seems way too far forward to be useful. Im gonna have to reseatthis before I mount it.

Re: 1 front 2 rear drop
I bought my rear bar many years ago. Had to use longer spacers and bolts to get the bar leveled for max effect. Rear springs are 3" drop.
It made a big difference. More responsive steering and less body roll in corners. I also have a stock bar on the front from a junkyard C10.

Re: 1 front 2 rear drop
Thanks for the photos! POLs website only showed photos with aftermarket trailing arms. Thats where I want to mount mine. Looks like a similar size bar.
