| Item | Notes |
|---|---|
| COR-4804341 Pro Series 3-link upgrade | If 3-link front geometry is the goal — either now or later — see COR-4804341 for the complete Pro Series 3-link kit. Note that ordering COR-4804341 after this kit may duplicate the lower arms and crossmember. Text (469) 407-7538 to confirm the correct upgrade sequence before ordering. |
| Professional installation labor | Qualified shop with ZJ front suspension experience recommended. Not included. |
Critical Compatibility
| Condition | Interaction | Action Required |
|---|---|---|
| Crossmember — install before control arms | The crossmember must be installed per Clayton's sequence before the control arms are attached. The crossmember provides the structural foundation for the lower arm geometry. | Install crossmember first per Clayton's installation instructions. |
| Front driveshaft operating angles | The longer arm geometry changes front caster angle at lift height. Verify front driveshaft U-joint operating angles after installation. Unlike the Pro Series 3-link kit (COR-4804341), a CV-style front driveshaft is not required for this standard long arm kit — but driveshaft angle should be confirmed post-install. | Check front driveshaft angle after setting caster. Correct if operating angles are outside acceptable range. |
| Front alignment — mandatory | A long arm front conversion changes caster, camber, and toe simultaneously. Full front alignment is mandatory before highway driving. | Schedule alignment immediately after installation. |
| Upgrade path to COR-4804341 | If 3-link front geometry is the eventual goal after installing this kit, the upgrade path depends on whether the crossmember and lower arms from this kit are compatible with the COR-4804341 components. Unlike the TJ/LJ where a separate conversion add-on (COR-4805015) allowed 3-link conversion without duplicating lower arms, no ZJ-specific 3-link add-on SKU was available in this session. | If 3-link is the eventual goal, text (469) 407-7538 before ordering this kit — ordering COR-4804341 directly may be more cost-effective than installing this kit and then upgrading. |
| Lift height minimum — 4" | Below 4", factory short arm front geometry is within acceptable parameters. | Confirm front lift height is 4" or greater before ordering. |
| ZJ platform verification | ZJ production ended in 1998. Source documentation contained a typo ("1993–2026") — confirmed fitment is 1993–1998 only. | Confirm vehicle year is 1993–1998. |
Installation Notes
Skill level: Intermediate to advanced. No welding required — bolt-on front long arm replacement. A qualified shop with ZJ front suspension experience is recommended for correct geometry setting and mandatory post-install alignment.
Step 1 — Crossmember installation:
- Install the crossmember per Clayton's installation instructions before installing any control arms.
Step 2 — Control arm installation:
- Install the upper and lower adjustable control arms at initial length per Clayton's geometry specifications for your lift height.
Step 3 — Geometry setting:
- Set caster and pinion angle with the vehicle at static ride height.
- Torque all control arm hardware at ride height — not at full droop or compression.
Step 4 — Driveshaft and alignment:
- Verify front driveshaft U-joint operating angles — longer arm geometry changes caster angle, which may affect driveshaft angles.
- Complete full front alignment — caster, camber, and toe — before highway driving.
Required tools (qualified shop):
| Tool | Required |
|---|---|
| Vehicle lift rated for ZJ | Yes |
| Torque wrench | Yes |
| Full socket and wrench set | Yes |
| Geometry setting and measurement equipment | Yes |
| Alignment equipment or appointment | Yes |
Common Questions
What is the difference between this and COR-4804341 (Pro Series 3-link)?
Geometry type, installation complexity, and fabrication requirements. COR-4804341 is the Pro Series 3-link kit — it includes weld-on upper arm mount brackets, a 3-piece crossmember, double-adjustable lower arms, and a single upper 3-link arm for maximum front axle articulation. It requires welding, a custom exhaust specifically to clear the upper 3-link arm routing, and a front CV-style driveshaft. COR-4804041 (this kit) is the standard 4-link long arm — bolt-on, no welding, no exhaust modification, no CV driveshaft requirement. For a significant improvement over short arm geometry at 4"–8" without fabrication requirements, COR-4804041 is correct. For maximum front articulation via 3-link geometry with fabrication capability available, COR-4804341 is correct.
Can I upgrade to 3-link geometry later if I start with this kit?
Possibly — but confirm the upgrade sequence with OFAS before ordering. Unlike the TJ/LJ lineup where a dedicated 3-link conversion add-on exists (COR-4805015), no ZJ-specific 3-link add-on SKU was confirmed in available source data. Ordering COR-4804341 after this kit may duplicate some hardware. If 3-link is the eventual goal, it may be more cost-effective to order COR-4804341 directly rather than this kit first. Text (469) 407-7538 before ordering to confirm the correct build sequence.
Does this require a CV-style front driveshaft?
No — unlike the Pro Series 3-link kit (COR-4804341), this standard 4-link long arm kit does not require a CV-style front driveshaft. Verify front driveshaft U-joint operating angles after installation as a standard post-install check.
Does this require exhaust modifications?
No — unlike COR-4804341 where the upper 3-link arm creates a specific exhaust clearance conflict, this standard 4-link long arm kit does not require exhaust modifications.
What is the warranty?
Clayton Off Road provides a lifetime warranty on all control arms in this kit — upper and lower. Confirm full terms at claytonoffroad.com/pages/warranty-policy.
The Obsidian Take
This kit is for the 1993–1998 Grand Cherokee ZJ owner running 4" to 8" of front lift who wants to replace the short arm front geometry with long arm geometry without requiring a certified welder, a custom exhaust, or a CV driveshaft. The Currie Johnny Joints, GIIRO bushings, and included crossmember bring the correct joint specification to a bolt-on installation format.
The comparison to COR-4804341 is the buyer decision. COR-4804341 delivers maximum front articulation through 3-link geometry at the cost of welding, custom exhaust specific to the upper arm routing, and a CV driveshaft requirement. COR-4804041 delivers meaningful long arm front geometry improvement over short arm without any of those requirements. For a trail-capable ZJ that still functions without a dedicated fabrication shop build, COR-4804041 is the correct front long arm upgrade.
The one open question before purchasing this kit — if 3-link geometry is the eventual goal — is whether the crossmember and lower arms from this kit can be retained when upgrading to COR-4804341, or whether ordering COR-4804341 directly is the better single purchase. That answer requires a quick confirmation call with OFAS before either kit ships.
It is not for the WJ, WK, or Wrangler. It is not for lifts below 4". And it is not the correct first purchase for a buyer who already knows 3-link geometry is the goal — that buyer should confirm the upgrade path before ordering.
Manufacturer Data Disclaimer
Product specifications and fitment data are sourced from Clayton Off Road product documentation and authorized product information. Actual product dimensions, fitment details, and geometry specifications may vary by specific vehicle configuration, lift height, and manufacturer updates. Source documentation contained a year range error ("1993–2026") — confirmed fitment is 1993–1998 (ZJ production years only). Confirm all build requirements with Clayton or OFAS before ordering.
Non-Returnable Notice
Suspension components are non-returnable once installed. Confirm vehicle identity (1993–1998 Grand Cherokee ZJ only — not WJ, WK, or Wrangler), lift height (4"–8"), and upgrade path goals (if 3-link geometry is planned, confirm the correct build sequence before ordering). Text (469) 407-7538 with any fitment or build questions before your order is placed.
