The Jeep Grand Cherokee widebody build is one of the most underrated projects in the aftermarket world. The WK2 Grand Cherokee — especially the SRT and Trackhawk models (2012–2021) — combines SUV practicality with legitimate performance credentials. Adding a widebody kit transforms this already aggressive SUV into something that stops traffic. This guide covers the full build: widebody flares, front bumper, wheels, tires, and every detail you need to execute a clean Jeep Grand Cherokee widebody kit build.
Why the Grand Cherokee Makes an Incredible Widebody Platform
- Performance pedigree — The SRT packs a 6.4L Hemi (475 HP), and the Trackhawk brings a supercharged 6.2L Hellcat engine (707 HP). These aren’t just SUVs — they’re legitimate performance machines.
- AWD system — All-wheel drive means you can actually put all that power down, especially with wider tires.
- Aggressive proportions — The WK2’s squared-off wheel arches and wide stance are already widebody-adjacent. Adding flares amplifies what’s already there.
- Rarity — Widebody Challengers and Chargers are everywhere. A widebody Grand Cherokee stands out at every car show and meet.
The Vicrez Demon Style Widebody Kit for Grand Cherokee
Vicrez offers a Demon Style widebody kit for the 2012–2021 Jeep Grand Cherokee SRT and Trackhawk. Here’s what makes it special:
Kit Components
- Front fender flares (left + right) — Extends approximately 3 inches per side
- Rear fender flares (left + right) — Matches front extension for symmetrical widening
- Full hardware kit with installation guide
Material
Polypropylene (PP) — 3D-scanned from the WK2 body for precision fitment. The same OEM-quality material that makes Vicrez’s Charger and Challenger kits the industry standard. Flexible, impact-resistant, paint-ready.
Fitment
Designed specifically for the SRT and Trackhawk trims, which have wider factory fenders and unique bumper designs compared to Laredo/Limited models. Verify your trim level before purchasing.

Build Phase 1: The Widebody Kit Installation
Preparation
- Wash the vehicle thoroughly — especially wheel wells and lower body panels.
- Remove wheels and fender liners for full access.
- Clean mounting surfaces with rubbing alcohol.
Test Fitting
The Grand Cherokee’s fender geometry is more complex than a sedan’s — the wheel arch has compound curves and integrates with the door and quarter panel. Take extra time during test-fitting:
- Clamp flares in position before marking any holes
- Check door clearance on all four doors
- Verify alignment with the factory body line that runs along the midsection
Trimming and Mounting
Follow the same process as any widebody installation: mark, trim factory fender lip conservatively, drill pilot holes, mount with hardware and 3M tape. The PP material allows fine adjustments with a heat gun.
Time Estimate
10–14 hours for a complete install. The Grand Cherokee’s larger body panels and more complex fender geometry add time compared to a sedan widebody installation.
Build Phase 2: Wheels and Tires
Critical: Bolt Pattern
The Jeep Grand Cherokee uses a 5x127mm (5×5″) bolt pattern — different from the Charger/Challenger’s 5x115mm. You CANNOT use the same wheels. Ensure any wheels you purchase are specifically for the Jeep bolt pattern.
Recommended Setup
- Wheel size: 20×10.5″ or 20×11″ with appropriate widebody offset
- Tire: 305/35ZR20 — the VCorsa VT101 is ideal due to its reinforced sidewall, which is critical for the Grand Cherokee’s 4,800–5,400 lb curb weight
- Style options: Hellcat, Demon Redeye, and VXC styles are available in the Jeep bolt pattern
Wheel & Tire Packages
The easiest approach: a complete wheel and tire package spec’d for the Grand Cherokee. Ships mounted and balanced with the correct bolt pattern, offset, and tire size. No guesswork, no compatibility concerns.
Build Phase 3: Front Bumper Upgrade
The Grand Cherokee’s front bumper is a defining visual element. For a widebody build, an upgraded front bumper ties the wider fenders into a cohesive front-end design.
Options
- SRT-style bumper — If you’re starting from a Laredo or Limited, an SRT bumper swap immediately transforms the front end.
- Aftermarket aggressive bumper — Wider air intakes, deeper splitter integration, designed to flow with widebody flares.
Front Splitter
A front splitter extension adds the finishing touch below the bumper. Polypropylene construction is essential here — the Grand Cherokee’s approach angle means the splitter will encounter curbs, speed bumps, and parking blocks regularly.
Build Phase 4: Rear Aero and Details
Rear Diffuser
An aftermarket rear diffuser fills the gap between the exhaust tips (quad tips on SRT/Trackhawk) and adds visual depth to the rear end. Look for designs that match the widebody’s aggressive proportions.
Mud Flaps
Often overlooked but important on an SUV widebody build. Wider fenders throw more road debris. Quality mud flaps protect the paint and the vehicle behind you.
Build Phase 5: Hood and Finishing Touches
Hood Options
The SRT and Trackhawk already have functional hoods with heat extractors. Aftermarket options include:
- Carbon fiber SRT hood — weight savings with factory-style appearance
- Demon-style scoop hood — maximum aggression
- Vented/louvered hoods — improved engine cooling
Tinted Lights
Tinted or smoked headlights and taillights complement the widebody look. Use quality tint film — not spray paint — to maintain light output and legality.
SRT vs. Trackhawk: Build Considerations
| Factor | SRT (6.4L NA) | Trackhawk (6.2L SC) |
|---|---|---|
| Power | 475 HP | 707 HP |
| Weight | ~4,800 lbs | ~5,400 lbs |
| Factory Hood | Heat extractors | Larger heat extractors |
| Brakes | Brembo 6-piston front | Brembo 6-piston front |
| AWD System | Quadra-Trac II | Quadra-Trac II (supercharged) |
| Widebody Kit | Same fitment | Same fitment |
| Tire Priority | Performance | Reinforced sidewall critical |
The Trackhawk’s additional weight and power make reinforced tires (like the VCorsa VT101) especially important. The 707 HP supercharged engine puts massive stress on rear tires — 305-width rubber is a necessity, not a luxury.
Total Build Cost Estimate
| Component | Budget Range |
|---|---|
| Widebody Kit | $1,400–$2,000 |
| Paint (kit) | $500–$1,000 |
| Wheels & Tires (package) | $2,500–$4,000 |
| Front Bumper/Splitter | $400–$800 |
| Rear Diffuser | $300–$600 |
| Hood (carbon fiber) | $800–$1,800 |
| Mud Flaps | $100–$200 |
| TOTAL | $6,000–$10,400 |

Frequently Asked Questions
Does Vicrez make a widebody kit for the Jeep Grand Cherokee?
Yes. Vicrez offers a Demon Style widebody kit for the 2012–2021 Jeep Grand Cherokee SRT and Trackhawk. It’s made from polypropylene with 3D-scanned fitment. Shop it here.
Do Charger/Challenger widebody wheels fit the Grand Cherokee?
No. The Grand Cherokee uses a 5x127mm bolt pattern, while the Charger/Challenger use 5x115mm. You need Jeep-specific wheels. Vicrez offers widebody wheel styles in both bolt patterns.
What tire size works for a widebody Grand Cherokee?
305/35ZR20 on 20×10.5″ or 20×11″ wheels is the standard. The VCorsa VT101 in this size is specifically designed for the load demands of heavy SUVs like the Grand Cherokee.
Can I install a widebody kit on a non-SRT Grand Cherokee?
The Vicrez Demon Style kit is designed for SRT and Trackhawk models, which have different fender and bumper geometry than Laredo/Limited/Overland trims. Fitment on non-SRT models is not guaranteed and may require modifications.
How long does a Grand Cherokee widebody installation take?
Plan for 10-14 hours for the full widebody kit installation. The Grand Cherokee’s larger body panels and complex fender geometry add time compared to sedan applications.
Is the Trackhawk too heavy for aftermarket wheels?
Not if you choose the right components. The Trackhawk weighs approximately 5,400 lbs, which means you need wheels rated for the load and tires with reinforced sidewalls. The VCorsa VT101’s 107W load rating handles Trackhawk weight confidently.
