|---|---|---|---|---|
| 1993–1998 | Jeep | Grand Cherokee ZJ | All trims | Welding required; custom exhaust for upper 3-link arm clearance required; front CV driveshaft required |
Before ordering — confirm all four:
- Vehicle is a 1993–1998 Grand Cherokee ZJ — not a WJ, WK, or Wrangler
- A certified welder is available for the weld-on 3-link upper mount brackets
- A front CV-style driveshaft is sourced and ready — confirm with Clayton whether SYE kit is also required for your ZJ transfer case
- A custom exhaust to clear the upper 3-link arm routing is planned — this is a more specific requirement than a general lift height exhaust modification

Does NOT Fit
| Exclusion | Reason |
|---|---|
| Jeep Grand Cherokee WJ (1999–2004) | Different front suspension architecture — WJ-specific system required |
| Jeep Grand Cherokee WK (2005–2010) | Different front suspension architecture |
| Jeep Grand Cherokee WK2 (2011+) | Different front suspension architecture |
| Jeep Wrangler TJ / LJ / JK / JL | Different platform and front suspension architecture |
| Jeep Gladiator JT | Different front suspension architecture |
| Buyers without a certified welder | Weld-on upper mount brackets are load-bearing suspension components — tack welds are not acceptable |
| Buyers who have not planned the custom exhaust | The upper 3-link arm routing creates a specific exhaust clearance conflict — the exhaust must be planned around the arm position, not just general lift height |
| Buyers without a front CV driveshaft sourced | Required before driving after this conversion — confirm SYE requirement with Clayton before sourcing |
| Trucks with aftermarket front axles without a compatible truss | D30 front truss must be installed before welding axle-side upper arm mount; aftermarket axles require a compatible truss sourced separately |

Critical Compatibility
| Condition | Interaction | Action Required |
|---|---|---|
| Custom exhaust — upper 3-link arm clearance | The upper 3-link arm's routing position creates a specific conflict with the factory ZJ exhaust path. This is different from a general lift height exhaust modification — a standard lifted-truck exhaust reroute may not provide adequate clearance for the upper arm. The exhaust must be fabricated with the upper arm position as the primary routing constraint. | Plan custom exhaust with upper arm position in mind. Have the arm position confirmed before exhaust fabrication begins. |
| Front axle truss — install before upper mount weld | D30 front truss must be installed at the front axle tube upper arm attachment point before welding the mount. Without the truss, sustained upper arm loads can deform the axle tube wall. | Install D30 front truss (or compatible aftermarket truss) before welding. |
| Weld-on upper mount brackets — permanent | Full-penetration welds on all contact surfaces required. No tack welds on load-bearing suspension brackets. | Certified welder with off-road chassis fabrication experience required. |
| 3-piece crossmember — install first | The 3-piece crossmember provides the structural foundation for the lower arm geometry and must be installed before control arms are attached. | Install crossmember per Clayton's installation sequence before any control arm installation. |
| Front CV driveshaft — SYE confirmation | Source confirms CV-style driveshaft required but does not specify SYE kit (unlike Wrangler kits). ZJ transfer case configurations (NP231, NP242) may handle driveshaft angle differently. | Confirm with Clayton or OFAS whether SYE kit is required for your ZJ's specific transfer case before sourcing the driveshaft. Text (469) 407-7538. |
| Double-adjustable arm geometry | Both ends of each lower arm independently adjustable. Set caster and arm length at ride height per Clayton's specifications. | Set all parameters at ride height after full installation. |
Installation Notes
Skill level: Expert — professional fabrication required.
Phase 1 — Preparation:
- Confirm ZJ identity (1993–1998 Grand Cherokee — not WJ or WK).
- Install Clayton D30 front truss (or axle-specific truss for aftermarket axles) on front axle tube at upper arm mount location before welding.
- Plan custom exhaust fabrication based on upper 3-link arm position.
- Confirm front CV driveshaft is sourced and SYE requirement is confirmed with Clayton.
Phase 2 — Crossmember installation:
- Install the 3-piece crossmember per Clayton's installation instructions before installing control arms.
Phase 3 — Weld-on upper mount bracket installation:
- Position the 3-link upper arm mount brackets per Clayton's instructions — verify position and angle before welding.
- Full-penetration welds on all contact surfaces. No tack welds.
- Apply weld-through primer and chassis paint to all bare metal at weld zones.
Phase 4 — Control arm installation and geometry:
- Install double-adjustable lower control arms at initial length per Clayton's specifications.
- Install upper 3-link arm using LH/RH thread adjustment.
- Set caster and pinion angle at ride height.
- Torque all hardware at ride height.
Phase 5 — Exhaust and driveshaft:
- Complete custom exhaust — routed to clear upper 3-link arm position.
- Install front CV driveshaft (and SYE kit if required).
- Verify front driveshaft operating angles.
Phase 6 — Alignment:
- Complete full front alignment — caster and toe.
- Inspect full suspension travel for binding or contact.

Common Questions
What makes this different from Clayton's Wrangler front long arm kits?
Two things: the 3-piece crossmember and the exhaust requirement specificity. The ZJ's front suspension layout requires the 3-piece crossmember included in this kit. The custom exhaust requirement on this kit is driven specifically by the upper 3-link arm's routing position — not just by general lift height geometry. Plan the exhaust fabrication around the arm position, not around the lift height.
Do I need an SYE kit with the front CV driveshaft on my ZJ?
The source documentation for this kit specifies a front CV-style driveshaft without confirming an SYE kit requirement — unlike Clayton's Wrangler kits which specified both. The ZJ's NP231 or NP242 transfer case may handle front driveshaft angles differently than TJ/LJ/JK transfer cases. Confirm with Clayton or OFAS whether an SYE kit is required for your specific ZJ transfer case before sourcing the driveshaft. Text (469) 407-7538.
Why does the exhaust need to be custom rather than a standard lift exhaust?
The upper 3-link arm creates a specific routing conflict with the factory ZJ exhaust that a standard lift height exhaust modification may not address. The arm position — not just the lift height — determines where the exhaust cannot run. Have the arm positioned (or its final position confirmed) before the exhaust is fabricated.
Does this fit the WJ (1999–2004 Grand Cherokee)?
No — the WJ has different front suspension architecture. This kit is ZJ-specific (1993–1998 only).
What is the warranty?

The Obsidian Take
This kit is for the 1993–1998 Grand Cherokee ZJ owner building a dedicated front 3-link long arm suspension. The 3-piece crossmember, double-adjustable lower arms, Currie Johnny Joints, GIIRO bushings, and LH/RH adjustable upper arm are the correct Pro Series hardware specification for the ZJ platform — and the four fabrication requirements (welded upper mount brackets, custom exhaust specific to upper arm routing, front CV driveshaft with SYE confirmation, D30 front truss before welding) are the build gates.
The exhaust distinction is the one that catches buyers who have built other long arm systems before. Most long arm exhaust modifications are driven by lift height geometry. This one is driven by the upper arm position. Those are different routing constraints, and planning the exhaust around lift height alone may leave the arm without clearance.
It is not for the WJ, WK, or any Wrangler. It is not a bolt-on kit. And it is not complete until the SYE question is resolved with Clayton before the driveshaft is sourced..
Manufacturer Data Disclaimer
Specifications sourced from Clayton Off Road product documentation and authorized product information. Actual dimensions, fitment details, exhaust clearance requirements, and driveshaft specifications may vary by specific vehicle configuration, transfer case type, and manufacturer updates. Confirm all build requirements with Clayton or OFAS before ordering.
Non-Returnable Notice
Suspension components are non-returnable once installed. This kit requires permanent welding to the ZJ frame and front axle. Confirm vehicle identity (1993–1998 Grand Cherokee ZJ only), custom exhaust plan (upper 3-link arm routing — not general lift height), front CV driveshaft sourced (confirm SYE requirement with Clayton), and D30 front truss sourced before ordering. Text (469) 407-7538 with any fitment or build questions before your order is placed.
