- 1996 Jeep Grand Cherokee Laredo 4x4 with 5.2 V8 and automatic transmission. Full info below...
Suspension Info:
Rear is on RE 3.5" XJ front springs. It has the IRO long arm kit with sub frame which allows fixed upper arms to be adjusted and the lowers are adjustable. Rear shocks are Doetsch Tech 8000 Prerunner Series part# 8403 which are 32" extended, 18.7" compressed, 13.3" of travel with integrated bump stops. Rear uses a Rusty's Offroad adjustable track bar. Rear drive shaft is stock with no issues.
The front is on RE 3.5" springs with JKS ACOS, Iron Rock Offroad long arms and IRO 3 piece subframe assembly. This kit has a one piece driver side control arm called the Iron Y which includes both the lower and upper arm in one piece with a caster adjuster. The passenger side uses only a lower control arm, no upper. Front shocks are Doetsch Tech 8000 Prerunner series part# 8421 which are 32" extended, 18.25" compressed, 13.75" of travel. The shocks are mounted to IRO bar pin eliminators. Extended stainless steel brake lines were installed to support the additional lift and flex. Front uses a Rusty's Offroad adjustable track bar with HD frame mount. Front drive shaft is a double cardan u-joint style to replace the OEM CV shaft which broke and also would not have worked with the long arm kit. JKS Quicker Disconnects which are adjustable are used on the front sway bar.
Steering Info:
Iron Rock Offroad OTK, over the knuckle, steering kit. The kit includes a 1.25" solid cold rolled steel tie rod and drag link with 5/8" grade 8 hardware. This required us to drill the steering knuckles on both sides as well as the drop pitman arm with a 5/8" drill bit. The kit is very solid and no steering stabilizer is being used.
Check out my other videos if you want more info on the steering box brace which has been a great addition since I'm running 35x12.50 tires. The steering box was recently replaced with a new one. We've swapped out the drop pitman arm for one that is about 2" shorter than the one we had installed previously because it will work better with my lift and IRO OTK steering kit.
Axle Info:
The front is a Dana 30 with IRO almost alloy Spicer 760x u-joint shafts, Solid diff cover, stock gears, and no lockers. The CV differential yoke has been replaced with a u-joint yoke for the new drive shaft. The axle will soon be rebuilt with 4.88 gears, and Aussie locker. The font axle also has heavy duty Rusty's Offroad lower control arm mounts to replace the bent stock ones.
The rear is a Dana 44 with stock gears and no locker. It will soon be rebuilt with 4.88 gears and Aussie locker.
Tires and Wheels:
35x12.50x15 Goodyear Wrangler MT/R Kevlar on OEM 15x7 wheels with 2" wheel spacers.
Jeep also has IRO on board air, Rough Country 9500 lb winch and mounting plate, Taurus 2 speed electric fan and B&M Supercooler.
5.2 V8 Engine Notes:
The motor is finally dry as a bone, leak free thanks to Joel Gonzalez!!! Oil pan was dropped and rear main bearing cap was removed because the two piece rear main seal was leaking. The rear main seal was replaced and a high volume, 25% over stock, Melling oil pump was installed. The pan was resealed with a Fel-Pro one piece gasket. The timing chain had some slack in it so it was replaced along with new timing gears on the crankshaft and camshaft. A new timing cover was installed with a new front seal to replace the original timing cover which had a hole in it. The original harmonic balancer was cleaned up and reinstalled along with the original crankshaft pulley. A new water pump was installed with a new bypass hose to the intake manifold. The thermostat housing was replaced along with a new 185 thermostat and Fel-Pro gasket. A new tensioner was installed because the old one was nasty to say the least. The original broken EVAP canister, damaged by the front driver side tire, has been removed and replaced with a new relocated canister. A new power steering pump was installed.
The motor also has an MSD external coil and K&N intake and air filter.
Muffler was a Flowmaster 40 series cutoff before rear axle, but muffler has now been removed. Exhaust setup from muffler to engine is stock with brand new catalytic converter.
Special Thanks: Thanks to my great friend and mechanic Joel Gonzalez for all of his hard work and dedication to Project ZJ. Thanks to Mario for selling me my first Jeep. Thanks to Nate and Mitchell for the awesome compressor mount. Thanks to Mark and Mike at All Muffler Service for their work on my exhaust and also for removing the stock lower control arm mounts in the front. Thanks to Rob at Les Schwab for all of the great advice and for doing my initial alignment. Thanks to Redline Tire for doing my final alignment and mounting and balancing my new tires. Thanks to all my loyal UA-cam subscribers for their continued support and comments!!!
This makes me want to sell my 98' XJ and get a ZJ. You have yours looking and flexing awesome. Love watching your videos.
Mark A. Thanks man, appreciate the compliments and glad you enjoy the videos!
Mark A. gotta love all around coils of this model jeep, go zj!
Glad to see another video. Jeep is looking good Ryan.
BuddyLe3 Thanks! I have another quick update video uploading.
im looking at the iro front long arm upgrade for my 99 wj. 6.5 inch lift. also going to get some new 6.5" coil springs with some bilstein 5100 series shocks, addco rear sway bar and an adjustable front track bar. cant wait for February!! income taxes!!
that is some flex kit bro
+Steven Naranjo Been very happy with Iron Rock Offroad products. Check out ProjectZJ.com for more info and videos on the rig.
Yea they can my 95 grand Cherokee gets sum good. Flex with just the short arms I wanna get some stickers off you to rep that zj hear in new mexico .
Andrew Cordova Yeah I was always amazed at the flex even with short arms. Stickers are available in the online store at ProjectZJ.com! If you get one send me a pic on Instagram (instagram name is projectzj.c0m with a zero) and I'll repost it on my page so all the followers can see.
Sick
Now that's a flex FLEX THIS
Andrew Cordova And they say Grand Cherokees can't flex haha
Great flex
John Krum Thanks!
Got me Nervous when Heard you had a problem with my new IRO LA kit. Well my friend, that is a problem I will not mind having.
mikesadass Haha yeah I feel the same way!
did that crosspiece in front of the transfer-case come with the suspension? i've got a 96 zj too but doesn't have anything to protect the transfer-case is like a jeep version of an outy belly button >.< looking for a skidplate to protect the whole thing for high center situations. Awesome zj though =)
Scott Brown Yeah that's the Iron Rock Offroad front long arm subframe. IRO is shipping me a belly skid plate that bolts onto the back of the subframe and the unibody. Excited to put it on because I've hit my transfer case on a rock before.
Very nice! Doing some research for my project. What wheels are those? They look like TJ "Canyon" Wheels which are actually 15x8, and not 15x7 like your videos description. Am I right? I don't think running 12.50 wide tire on a 7" rim is advisable from what I've heard.
mikedashg Canyons from TJ are 15x8 and have a slightly different look than the 15x7 Canyons that came on ZJ. I ran a 35x12.5 on 15x7 wheels for a long time with no issues, you just have to dial in the air pressure for even wear (lower than normal psi)
KO.
You ever gonna get some heavy duty bumpers/sliders? I think that would really top your build off! But just my opinion :)
Vanshi DK I plan to keep the stock bumpers because I have jack and tow points front and rear and was able to keep the stock bumper with the winch mount setup. I really like the stock bumper look for some reason. I'm uploading a video right now though talking about my plans for custom rock sliders to replace the damaged rocker panels. Stay tuned!
Not sure where you are located but my buddy has a custom body/metal shop I have access to all the metal benders , plasma cutters , etc I made some new real pimp panels . Ill have to upload some vids. I bought a zj 5 yrs ago for 900 bucks and literally rebuilt it from the ground up. Including rebuilding the trans and dropping a 4.0 with only little under 100k . Now there are no more fun trails to hit in my neighborhood because like you said its hard to find a place to get it to flex like it wants to!!!!! Lol where you located ? Im in CT
And f*ck those heavy duty bumpers lol looks way better stock !
What kind of coil spring retainers are those ? I have the same jeep with the long arms+ SYE and am looking for a good type of coil retainers
On the top side I had JKS ACOS up front and IRO extensions in the rear. On the bottom side I had the factory retainer in the rear and Ruff Stuff coil platforms on the front. They added some height but worked great.
How many inches of suspension do you have and how many inches of tire? thank you
Back then I think it was around 7" lift on 35" tires with 14" travel shocks
Flex on that tire in front of you on a big old piece of equipment
is this the 7" kit or the 5" kit from IROK?
I did a lot of experimenting with different coil springs. Started at around 5.5 and ended up at 7.
