Re: Dropping the 1 ton!

I did find these for the front. What do you think? I could also lower the coils an inch also, and have a 4 inch drop in the front. |

Then just trim the stock coils. (1/2 coil = approximately 1" of drop).

Re: Dropping the 1 ton!
Would they affect my steering and other linkages?
Where is the dually forum you mentioned? And, how would I get as much as a 7'' drop in the rear, would i need more than a axle flip? |

Re: Dropping the 1 ton!
A flip kit on a 1-ton rear end is way more than 5" of drop. Measure the height of the spring pack & the OD of the axle tubes to calculate how much drop you might get. On my dually w/a HD Dana-70 & those big axle tubes, a flip kit was 7" of drop.....
Up front, swap in drop spindles before replacing the coils or using tubular/dropped a-arms. Then just trim a little off the current springs (no more than 1-coil is my recommendation).

Re: Dropping the 1 ton!
Thanks SCOTI, that is what I'm leaning towards doing now, any suggestions on good axle flip kit for my truck?

Re: Dropping the 1 ton!
The only one I'm aware of for a C20/C30 application is Western Chassis. From my searches, the other companies sold shackle & hanger kits.

Re: Dropping the 1 ton!
I don't know if i would have room to do a axle flip, it seems my springs are pretty flat. And for the heck of it, here is also a pic of my front suspension, does anythings seem out of the ordinary or unexpected being a 1 ton and all?

Re: Dropping the 1 ton!
Are frame noches usually required when doing an axle flip? Because the gap is 3 - 4 inches, so the axle will be right against the frame if placed on to the the leafs?
The second pic seems like a more accurage angle of the space i have to work with, there is around 2-3 inches between the axle and the bumper. |

Measure the distance you have now between the axle tube & the bottom lip of the frame-rail. That will tell you if there might be possible clearance issues. If so, it might require the addition of a c-cotch for clearance. If the c-notch is required, you'll more than likely bottom out @ the pumpkin/differential to bedfloor since the C20/C30 rear housings are physically larger vs the C10's 12-bolt. How low do you want to go......

Re: Dropping the 1 ton!
I guess i need some visuals to answer that, what is considered extreme to moderate.

Re: Dropping the 1 ton!
The top leaf spring is roughly 9.5'' from the bottom of the frame rail, and is 8'' from the metal holding the rubber bumper. The axle tube is roughly 3 1/4 think. So taking account into the parts i will be adding on for the axle flip, hows my room looking.
Is 7-7.5 crazy low or something? |

Re: Dropping the 1 ton!
Mine was about 6/8", rear was a flip with the overloads removed. The axle was about 1/2" from the axle with no notch.

7-7.5" rear drop is a good compromise; low but not so low it takes alot of re-work just to be able to use the truck as a truck. That being said, that leaves you w/approx 2.5" max space for rear compression travel. I'd consider 2.5" of compression travel pretty decent and/or about standard when driving a typical street type vehicle. Any more drop (or any more weight that causes the truck to squat), will infringe on that amount of travel & why you need to plan accordingly. Do you want your truck as low as Cochinos dually or the longbed lolife99 posted above? What size tires/wheels are you planning to run (what look do you like)? What is your budget?

I love as we get into this the more questions i get to answer, showing my lack of knowledge.... The two trucks look pretty close the same by my eyes, but anyone know the height of the long bed? As far as tires and wheels, i really want to run 20 inch wheels, and not sure what the means as far as tires, or width. Remember I'm keeping 8 lugs and have less wheel options. As far as my budget, this truck is going to be kept in my family forever, and money i put into it I don't want to be wasted with "is wish i would have done this instead", but saying that i know i can't do it all at once and am going to have to do it one step at a time. But as far as money goes, i don't want that to hold me back at all in my choices. If something is a little more expensive then it will take a little longer to save. |

Re: Dropping the 1 ton!
20" 8-lug wheels are going to be a decent size & still allow for some sidewall height. Do you plan to run the same size wheel front & rear or do you like the staggered look? Do you normally rotate your tires or would it be out of the question to not rotate them?
Sounds like your budget is flexible so you just need to pin-point a drop amount for the rear to determine the best course of action. The front end is pretty standard when going over 4" of drop: spindles 1st & then drop springs or cutting the originals. The poly bushings for the sway-bar are a must IMO as are some great quality shocks. Front parts list should read something like this: 3" dropped spindles-- Bell Tech = $411; Western Chassis = $388 trimming current springs = free Poly sway-bar bushings for HD 1.25" OE 3/4 1-ton app = $33 set/4 Great shocks/ Bilsteins = $70ea

Re: Dropping the 1 ton!
On tires again, I have not mentioned, but i drive the truck 200 miles at the MOST in a summer, come bad weather, it goes into the heated garage until spring.
I would I like the rake look some, but I'm leaning more towards level. 20's on all four sound good. As far as drop. A 6/8 or a 5/7 are both right there as options for me. Would would be needed to get down from a 5/7 to a 6/8? Would i just do a 3'' drop spindle and then cut 1.5 coils out of the spring? Could you post the Belltech link for those spindles you posted, i can't locate them on the Belltech website. Last edited by tc4x4; 01-10-2012 at 10:46 PM. |

Re: Dropping the 1 ton!
Both trucks are running stock height tires (or close to it) they should measure out to about 30 inches tall. Since you want 20" rims you can stay close to this tire height. 8 lug 20's are nice because most of the 10" wide rims have 5" of back spacing, perfect for a square body. I'm sure narrower wheels can be had for the front but these wheels are becoming very common thanks to the newer 4x4 trucks. I actually thought about converting my stepside over to 8 lug so I could use a set that I have sitting in the garage.

Re: Dropping the 1 ton!
Not a square body truck,... but it is a cool 8-lug truck.
http://67-72chevytrucks.com/vboard/s...d.php?t=498119 The original pics of it have Billet Specialties wheels. Later he chooses Intro wheels. There are some cool 8-lug wheels out there.
