Swappable Lift/improvement Parts

[88ComancheMitch]

Maybe this will be a sticky eventually, but I didn't see a topic that had everything in one place that would let you see some swappable parts from various vehicles. I'll kind of start a template...the idea is to have a list of stuff that can be directly, or almost directly, swapped. Hopefully I didn't miss this sticky/section somewhere.

 

Some applicable information. Some has been repeated.

 

Cherokee Junkyard and Budget Jobs

 

Suspension

 

Lift:

• ZJ coils lift approx 1-2" in the front
• F150 coils lift approx 3" in the front, but will cause a stiff ride. 
• Spring over axle swap in the rear lifts between 5-7" (wide variance here)
• For extended brake lines, large dodge ram vans from the same era will fit.
• TJ Coils fit, but will provide 1" less lift than what is specified (I.e. stock springs = 1" drop, 3 inch TJ coils = 2 inch MJ coils)

General

• Better ride and wheel clearance with WJ LCA's (UCA's will fit, but only give the benefit of a better ride to my knowledge)

 

Driveline:

 

Rear Axle

• Cherokee rear ends require spring perch relocation, but the D35 and Chrysler 8.25 fit
• Ford 8.8" will fit, and have commonly sought after gearing (3.73, 4.10, etc) and typically have disc brakes and posi-traction. (Will require spring perch relocation, 1" wheel spacers)

Brakes:

 

• WJ Brake booster/Master Cylinder. Upgrades braking--Must be done together. 
• YJ brake lines (3-4" longer)
• WJ Rotors and Calipers (Larger, most stopping power, check fitment with rims)
• Can convert from drum to disk using ZJ parts. Need everything from the backing plates out. Suggest using brake booster and master cylinder. 
• Dakota ('95-'00) Rear soft brake lines. 6" Longer
• K1500/GMC Front softlines-require some modification ('90-'95) 6" Longer
• KJ Disc brakes can be used to convert
• For extended brake lines, see lift section.

There's a thread on naxja called junkyard upgrades that has tone of info like this. I would link to it but am on my phone right now. Good stuff!

[Incommando]

The dual diaphragm upgrade is worth its weight in gold

[benjy_26]

95 C1500 brake hoses work for 5 inches of lift in the front with a bit of grinding.

 

ZJ steering box has a quicker ratio and bolts in

 

ZJ V8 Tie rod bolts in

 

ZJ aux tranny cooler makes for a dandy P/S cooler

 

ZJ spring isolators have a metal core and are stackable. Good for a cheeeeaaap budget boost or for leveling a rig from side to side

 

The zj 44A isn't as sought after as the 8.8, but I think if one is building a street 'Manche or keeping the tire size sane, it would make for a strong (enough), cheap, plentiful upgrade that is the right width and comes with discs to boot that is significantly lighter than the 8.8.

[Incommando]

The D44a is not a desired piece and has limited aftermarket support. I have read of guys replacing them with 8.25's....

Not every peg fits every hole...

 

I agree, the aftermarket SUCKS for the 44A.

 

BUT with the proper truss to alleviate the flexing issues, it should be a pretty strong axle. It has a beefier R&P set up than a regular 44, IIRC. One can also get decent gears for it, up to 4.56's I think.

 

I stand by my statement.

[88ComancheMitch]

More than one way to skin a cat. Sometimes whats available is whats best.

 

 

Awesome information guys. Keep it coming

I had this cut an pasted from somwere....

9. ZJ spring isolators = stronger, metal core, can be stacked
10. GM fullsize pickup shackles ('95-99) = 1.5" lift, better shackle angle
11. Thunderbird Front Coils ('83-97) = 3-4" lift (varies in lift and softness by year and trim package), will need top plate from strut too
12. Any 2.5" wide leaf spring can be used between to make a bastard pack (they may differ in stiffness and lift)
13. S10 Shocks (Rear only) = good for the lift you will get when you do a bastard pack
14. TJ Lift Coils (front only) = provide 1" less lift on an XJ than on a TJ

Brakes:
1. WJ brake booster
2. WJ Master Cylinder
3. YJ Brake Lines = 3-4" longer
4. Dodge Ram Van Brake Lines = 10-12" longer (for big lifts)
5. WJ Rotors/Calipers = bigger brakes and more stopping power (will fit 15" rims)
6. ZJ brake booster, master cylinder, proportioning valve = may need for disc conversion

2. XJ I-4 & some V6 = may have 3.73, 4.10, or 4.56 gears may have vacuum discos

4. XJ D44 = found in some but not all '87-'89 XJ's with Towing Package
5. Lincoln Lockers = welded spider gears, operates like a spool, must be a GOOD welder
6. MJ D44 = need new spring perches and shock mounts
7. XJ D30 = ('95-'99) non-disconnect, larger u-joints, high pinion, bolt in
8. Homebrew posi-locks for '84-90 vacuum disconnect D30s, eliminates vacuum actuation (use search function)

9. V8 ZJ front sway-bar
10. JK rear UCA = use as XJ LCA, its about 1-2" longer

Engine/Transmission/T-case:
1. Newer XJ intakes (may require some modification)
2. Mustang 5.0 Injectors = near bolt in (have 4 holes instead of 1, more fuel, better spray)
3. ZJ V8 alternator = more power to run accessories (some grinding required) 136A (for 1991 and newer XJ's).
4. Ford Electric Fan ('90-95 3.8L Taurus, '87-93 5.0L Mustang) = replaces mechanical fan, more cooling (8C607)
5. 2.5L Dakota Alternator = bolt in, upgrades to 117A
6. Dodge Neon Injectors = better throttle response 
7. '94+ V6 Dakota AX-15 = bolt in (but must use XJ bellhousing)

9. 5spd crossmembers give 3/4 inch t-case drop on autos with no loss in ground clearance
10. Hoodvents (i.e. Lebaron, Laser, Turbo Thunderbird etc.) = help keep ur 4.0 cool at low speeds
11. You can convert the closed system to open without replacing your radiator by using the fill cap from a 4.7 durango or dakota, cutting it into your upper hose, and replace your bottle with an MJ overflow tank or any that fit. Then cap off or eliminate the T'ed lines in the heater core.
12. Homebrew Slip Yoke Eliminator (use search function)


Body/Interior/Armor:
1. 97+ mirrors are direct bolt in to older XJ's and allow you to fold them in on tight trails.

3. ZJ gas tank skid = can be modified to fit 97+
4. GM power antennas replace your broken XJ's with little modification
5. XJ '97+ doors onto older cherokees = one piece windows and better mirrors
6. XJ overhead console = most commonly found in '00-01 or higher trim level, provides space for switches etc.
7. '97+ center console = can be made to fit '96 and older, gives you cupholders!
8.'96-00 Ford Explorer hatch shocks = lift your hatch about 3" lower but are beef (ever see one that doesn't work?) need modification for '97+
9. OEM skid plates (Front, Tranny, T-case, gas tank, found on "up-country" package XJ's)
10. OEM swing-out tire carriers, get the bumper with it, found mainly on '84-'90 XJ's

This is the first link I have up there. I'm going to start updating the original post as I have time.

[88ComancheMitch]

Anyone know if the 5 speed t case drop works on Comanches?

[yxmj]

Sorry  :dunno: Links were not working for me....oh well....can't have enough info  :thumbsup:

[Spectormj]

I'm getin tj coils tomarrow ill post up a pic once they are in

[benjy_26]

Don't TJ coils DROP us one inch?

[Spectormj]

ill find out tomarrow but i think it just is an inch under what it will lift a tj

[benjy_26]

Ah... TJ lift coils? Yeah. If you get 3" TJ coils they're 2"s on an MJ.

[pettus253]

Will I need to change out my transmission if i'm converting from 2wd to 4x4? 1990 2wd 2.5L. Have axles out of a 99 XJ.

[Incommando]

With the 4.0 drivetrain you would need to either get a 4wd tranny (easier) or convert your 2wd output to 4wd (harder). I am fairly certain that it is the same with the 4cyl's trannies.
