Re: My Build Thread (year+) on 71 Jimmy 4x4
Looks like you have a great starting point. If your not going to do any intense wheeling you should be safe using the stock running gear. I have those same seats and center console going into my blazer. Could you post up some good pics how you mounted them up?

Re: My Build Thread (year+) on 71 Jimmy 4x4
Sounds like a decent build plan. If you're going to actually wheel it, you may want to drop down to 35's or get more lift. 6" of lift might not be enough for 37's. You'll want at least 4.10 gearing to run the 37's without lugging the engine.
I'm not a big fan of the liner on the interior. If I were looking to buy a truck, I'd lean toward one with out liner that may be hiding something. From a practicality standpoint, it is a good idea. Are you going to wrap the seats in leather or something less prone to dirt than the cloth?

Re: My Build Thread (year+) on 71 Jimmy 4x4
I will have 9" of lift with the 3" body and 6" suspension. I think Im going to rebuild the 1-ton axles (got them already) with 4.56 gears. I will make sure 37's dont rub....seems like 9" would do it. Trimming isnt out of the question either.
Not sure about the seats yet...maybe go neoprene covers? I hate leather and vinyl with a passion, especially in idaho. Cold and cracky in winter, hot and sticky in summer. Need to be Hose-able or washable though. Dont have the rear seats mounted yet, but will post pics when I do. Fronts are simply sat in the floor and bolted down with backing brace. Probable re-do all that in the following build up

Missed the 3" body lift. You should be fine for clearance.

Re: My Build Thread (year+) on 71 Jimmy 4x4
I'd add fuel injection to your list, you'll be glad you did.
Some kind of 'real' seat mounts for those seat's with the three point belts. Why the body lift? 6" lift with basic trimming will clear the 37's. 4:56's or lower, depending on where you want the best performance. Thinking at all about cross over steering set up or hydro assist? How far do you want this truck to go in reality? Back roads, woods roads, trekking kinda stuff? Looking forward to watching this one morph. ![]() |

Re: My Build Thread (year+) on 71 Jimmy 4x4
Nice ride! I've got one myself. Doing a similar build, but mine will be a daily driver as well as a weekend warrior. Dunno if I'll upgrade to 3/4 or not, but will have a selectable locker front & rear as well as fuel injection. I figure better mpgs & more relible wheeling in the mountains. Looking forward to more progress pics. I should get to work on mine!

Re: My Build Thread (year+) on 71 Jimmy 4x4
With my body lift on my K20 I went with a borgerson u-joint for the steering and went with one of their collapsable shafts. That with my van tilt took care of the steering shaft issue associated with my body lift. Your build sounds like it will be fun to follow.

Re: My Build Thread (year+) on 71 Jimmy 4x4
Thanks everyone. Good to see some other Idaho owners. Im real close to Boise out here in Meridian off of US 20-26 (Chinden).
vtblazer....after seeing your wheeling pics and your Morp build I would love to hear all the suggestions you have because it looks like you've troubleshooted alot of the probs im going to have already. I will start researching Electronic injection and the hydro or crossover steering. As for your "How far do I want this to go" question.....I want the most Off-road capability that I can get without sacrificing being able to go on the pavement as well. Not talking cross country highway trips, but maybe 100 miles radius to get to the trails and around town for gas. It will be for fun, mudding, camping, exploring, and in Idaho there are alot of huge rocks in the road to traverse.

I've gone a wee bit past the 100 mile radius capabilities but thinking about reining it back some just to drive it more. Feel free to ask away, like the build direction and happy to help. ![]() |

Re: My Build Thread (year+) on 71 Jimmy 4x4
Ok my last axles didnt work out (d60F C14R), but Ive found another truck thats wants to donate its axles to my jimmy. Actually Im gonna get the whole Truck for $500, but the cab caught on fire and the motor is gone. Basically Im buying it for the drivetrain.
Its an 1987 Chevy 1ton Dually crew cab long bed. It has a Dana 60 Front and a Dana 70 dual rear w/4.10's. Also the driveline will be perfect to cut down after I get my lift on. Its from a crew long of course.. Any comments or advise on this? I know a D70 is similar to a corp 14 and Im getting it all for $500 and they are in good condition. What am i going to run into converting the DRW to SRW? Also we have all the tubing to start the Roll cage, and a body and suspension lift coming to grab 9" lift to start with

Re: My Build Thread (year+) on 71 Jimmy 4x4
I drilled out the plastic screws in the slip portion of the shaft and lengthened it about 2 inches before I started. Seemed to work well.

Why the need for a 3" body lift?

Re: My Build Thread (year+) on 71 Jimmy 4x4
Well, I tend to like body lifts as part of an overall lift.
They dont raise the center of gravity as mush as a equal size suspension lift. They dont change steering geometry or driveline angles. The truck needed new polys anyway, and the body lift kit w/bolts is cheaper to buy than trying to just find the right size bolts alone for the poly. Im having tube bumpers made and this way they wouldnt need moved up later if I decided to someday do a body lift. The 36's are temporary as rollers while I work, I just ended up with them when I bought the rims, so I figured I needed more than just the 6" suspension lift. Is there something wrong with BL's?

Re: My Build Thread (year+) on 71 Jimmy 4x4
Are you running a D60 or D44? In this thread you say D60 but in your other thread you have a rebuilt D44 from a 71 K20. What are you going with??

Re: My Build Thread (year+) on 71 Jimmy 4x4
A BLift that is installed properly will work fine.
There is a buzzz out there in the off-road community that sends negative vibes out to the body lift gods...not sure why? Center of gravety issue? Mee think No, I have been in many 'pucker factor' angles on the trail and survived from tippin over.. All I know is I have been wheeling with a BLift on my K5 for hmmmmm 16yrs now. I have never ever not even one time had an issue with them ![]() More ![]() ![]()

Re: My Build Thread (year+) on 71 Jimmy 4x4
Center of Gravity stays lower with a body lift.....
Rather than moving the whole truck, motor, tranny etc up with a spring, you are only moving the body up....which has to be like 1/3 the weight or less. The real downside is you dont gain any ground clearance on the running gear other than the tire size change you can now clear will gain you a couple inches on the ground. My axle story is convoluted I know...I have access to several sets that Ive decided on one way and changed my mind the next. Im really tempted to drop that dana 44 into it from the 71 k20 due to the myriad of other things like ease of steering and cost...but I keep thinking I'll kick myself later if I dont just do the D60 front. Im not sure I will wheel it hard enough to break things on the 44 if I build it right and mostly use it as a daily driver and camping rig. My max tire size will be 37 x pretty wide.
