in order to make a better FAQ than the one i have made already, im taking a survey to see what tire and lift you run. but, i dont want "i run 4in lift and 35s," thats too easy. i want to know EVERYTHING.

heres what i want:

1) truck info. is it an RC or a truck? what kind of truck (reg cab long bed, crew cab short, 1ton, half ton, etc) and what year.

2) what axles are you running? please dont say stock, actually tell me what they are.

3) what size lift, and who made it. also, tell if you trimmed your fenders, and if u can give a rough estimate of how much.

4) what size tires, and what make. 36x14.50 r15 boggers is what im looking for, not just 36's M/T's

5) what size rim, and its backspacing.

6) what kind of off roading do you do? mud, rocks, trails, sand, all of it?

like i said, i want to know everything. you dont have to answer every question, but answer as many as you can. any other details you feel i need to know to make an accurate FAQ, please include them! i need as many people as possible to respond to this so i have a good amount of info.

Thanx guys and gals,

1) 85 W350 Crew Cab
2) Front D60 / Rear D60
3) 3" Body 4" Syspension
4) 37x12.5 Super Swamper SSR's
5) 16x10 Mickey Tompson Classic Lock 4 1/4" BS
6) I try for a bit of all but alot or street & trails
This is what everything is so far, seems to be changing alot
1.85 Ramcharger
2.D44 front, 9 1/4 Rear, open 4.10's
3.Modified 4 inch RCC lift, fenders trimmed on front fenders a couple of inches by the bumper, 52 inch 1/2 ton rear springs up front, HD 3/4 ton 52 inch springs rear for a total of about 7 inches of suspension lift
4.3 inch body lift
5.35x12.50R15 Mickey Thompson Baja Claw Radials
6.15x10 Black Rockcrawlers unknown b/s
7. I like mud and trail riding on my personal trail(about 1.5 miles round trip)
A rear isn't gonna give you lift or effect lift , it doesn't matter if you got a D-70 or d-30 or a straight axle it isn't gonna effect lift,
so stock Dodge 350 crew
2" body lift
35 bfg's
16.5 x 9.75 x 5" BS
street,towing, trails, no water deeper than the hub, nothing to cause damage
some people say it does, some say it doest marty, so im asking just to make sure.

1) 75 Trailduster frame with home made roll bar in place of body, a 360/727/203 out of a 76RC, the 203case is actually out of a 79RC
2) front axle is a welded diff Dana 44 soon to have 4:88 gears
rear axle is a chrysler 8 3/4 welded diff with 4:88 gears, these axles are strong, light weight axles and are as good as , if not better than, a ford 9, I chose it over the 9 1/4 or dana 60 mostly for ground clearance purposes
3)I have about 5-6 inches of front lift, with 2-3 inch rancho leaf lift, and 4 inches of well placed steel between the frame and spring hangers, and home made front shock hoops that support my pro comp, 15 inch travel, shocks. The rear is undergoing mods to become a 1/4 eliptical with a Y bar to locate it correctly and will also get the long travel pro comp shocks.
After careful consideration, I trimmed/lifted the whole body off, and replaced it with pipe.
4)tires are 36x12.50x15 super swamper TSL radials on steel rims, I dunno back spacing , but they came off my 79RC
I really need 38's or 39.5's
5)I am planning a few new rims due to some rock rash and scuffs, for the new ones im having an idea for 3/16 in. round steel plates that will bolt on over the rim for protection, i will have to build them myself.
6)as for wheeling, it's Severe, Extreme, HardCore Rock Crawling, and i aint skeeered of a little rock rash
If i dont hear metal scraping on rock and snapping axle shafts, i aint wheeling hard enough.
I have done mud, sand, hills/trails and they cant raise the pucker factor like a good day on the rocks

Actually Marty, the dana 60 front has bigger diameter tube and the spring pad is taller, so you get about 1" of lift when you swap out a dana 44 for a dana 60. That is also why the dana 60 and 70 trucks came with a smaller block in the back compared to the dana 44, since the tube is wider and the spring perches are thicker.

Also, the 1 ton axles pinion shafts stick out farther, so doing a 1/2 ton to 1 ton swap could mean shortening driveshafts.
My truck has factory 3" blocks actually it might be 4" (i'll measure it in the morning) in the rear on the 70 and the axle tube is like a 1/2" diff overall resulting in a whopping 1/4" difference from 44 to 70 since the shafts are centered in the tube, to be technical axle diameters are a d44 is 3" a front is 2.75", a d60 is 3.1" , a d70 is 3.6" so you have a 1/8 and 1/4 in from d44 to d70 in lift
Yes Marty, the diameter barely results in height, but the spring perches are where it comes from. Like I said, swapping a dana 60 out for a dana 44 in a RAMCHARGER you get about 1" in height, and the depth of the pinion yoke would require a shorter driveshaft if you do not lift the front.

4) 32x11.5x15 BFG AT
5) 15x8 unkown backspacing
6) sand, trails (some minor rubbing when fully compressed and wheels turned)

Just a general thought: anyone if there is a way to measure backspace while the rim is mounted and if so, how? I think that would make it easier for people to answer that question also.
1. 86 RamCharger
2. 44/9.25
3. 2" Skyjacker, no trimming
4. 33X10.50 R15 (have had 12.50's, and soon will again) BFG AT's
5. 15x8, don't know backspacing.
6. Trails that moslty includes rock/slickrock, sand, dirt, rarely mud, Daily driver.
Santak you would have to measure from the face of the drum or disc hub where it is bolted to the rim and go to the rims edge
85 RC

2" lift via add-a-leaf springs

33x12.50 BFG T/A on 15x 9 inch rims. 51/4" backspace

No fender trimming, no problems with clearance unless I get
in a severe off-camber situation

9.25 rear, D44 front, 3:55 gears. LockRight in rear, front's open

Daily driver, mostly trails and rocks
1. 85 W 150
2. D44/9.25
3. Sagging stock springs
4. 31x10.5x15 BFG AT's
5. 15x8.5 w 5" backspace
6. Inner fenders have been eaten up by P.O., front corner of outer fender has been bent. Probably had at least 33's on it before.
7. Whatever I can find, desert, mud, hill climbing, trail running.

My springs are about an inch or so negative arch and I am pretty sure 33's would rub like crazy. I am probably going to add a set of rancho add a leafs for lift and go to 33's.

1/2 inch off front fenders in front of wheels for about 8" from the bottom up still rubs a little on the inner fender on the back side of the wheel well when flexing hard
