The Jeep Wrangler Rubicon 392 is what happens when Jeep drops the legendary 6.4-liter HEMI V8 into the most capable Wrangler trim. The result is a vehicle that completes 0-60 mph in approximately 4.5 seconds, tows 3,500 lbs, and can ford 32.5 inches of water - and it does all of this with a factory warranty. For Nassau County buyers who want the ultimate Wrangler, this is it.
Bottom Line: The Rubicon 392 is the no-compromise Wrangler for buyers who want maximum off-road capability and V8 performance without modification. It costs significantly more than a standard Rubicon, but it delivers factory-level V8 power that aftermarket conversions can’t match for reliability and warranty coverage.
- 6.4L HEMI V8 producing 470 hp and 470 lb-ft of torque
- Rock-Trac 4WD with 77.2:1 crawl ratio for serious off-road use
- Starting MSRP around $80,000 for base 392 trim
What Makes the 392 Different From a Standard Rubicon
The standard Jeep Wrangler Rubicon is already the most capable trail-ready vehicle Jeep makes at its price point. The Rubicon adds front and rear Dana 44 axles, electronic front and rear locking differentials, a Rock-Trac 4WD system with 4:1 low-range gear reduction, and disconnecting front sway bar for maximum articulation.
The 392 builds on that foundation by replacing the standard 3.6L Pentastar V6 with the 6.4L HEMI V8 from Jeep’s performance parts catalog. This isn’t a tuned engine or a high-output version of a smaller displacement powerplant - it’s the same 470-hp HEMI used in the Dodge Charger and Challenger R/T performance models.
The practical difference on Long Island’s roads is immediate: the Rubicon 392 pulls with authority from low revs, handles highway merges with reserve to spare, and produces a V8 exhaust note that’s genuinely distinctive. Off Long Island Expressway on-ramps or through tunnels, the sound is unmistakably different from the four-cylinder and V6 Wranglers.
Off-Road Capability That Exceeds Most Usage
The Rubicon 392’s off-road specifications exceed what most Nassau County and Long Island buyers will ever use. The 77.2:1 crawl ratio (Rock-Trac NV241OR transfer case x 4.56 axle ratio) is designed for technical rock crawling on trails that don’t exist in Nassau County.
For realistic Long Island use, the 392’s off-road advantage manifests in:
Beach driving access points where soft sand requires significant torque - the V8’s 470 lb-ft at low RPM is superior to the V6’s 260 lb-ft for maintaining momentum in loose surfaces.
Upstate New York trail use for buyers who use the Wrangler for weekend trips to the Catskills, Adirondacks, or Pennsylvania trails. The 392’s extra power handles mountain grades with loaded roof racks without the V6’s need to downshift aggressively.
Winter confidence on uncleared roads - the combination of all-terrain tires, locking differentials, and low-range capability makes the 392 one of the most capable vehicles available for genuinely compromised winter conditions.
"The 392 attracts a specific buyer who's done their homework - they want the HEMI, they want the factory warranty, and they don't want to compromise the Rubicon's off-road capability to get it. It's the Wrangler for buyers who want everything."

The Xtreme Recon Package
The Rubicon 392 Xtreme Recon Package adds 35-inch BF Goodrich All-Terrain tires from the factory - a significant upgrade that most owners eventually add to a standard Rubicon anyway, often at significant aftermarket cost.
What the factory Xtreme Recon includes:
- 35x12.50R17 BF Goodrich KO2 All-Terrain tires (or equivalent)
- 17-inch steel wheels with a Granite Crystal finish
- Raised suspension calibration to accommodate the larger tires
- Modified fender flares for the additional tire width
- 4.56 rear axle ratio (standard 392 runs 4.10)
The Xtreme Recon Package adds approximately $4,500-$5,000 to the 392’s price but delivers a factory-engineered tire-and-suspension package that maintains full warranty coverage - something pieced-together aftermarket builds cannot guarantee.
For buyers planning extensive off-road use, the Xtreme Recon is the configuration to request. For Nassau County buyers who want the V8 primarily for on-road performance and occasional capability, the standard 392 without the package is a more comfortable daily driver.
Fuel Economy and Operating Costs
The Rubicon 392 is not a fuel-efficient vehicle. EPA estimates are 13 MPG city and 17 MPG highway - figures that reflect the V8’s performance character and the Wrangler’s aerodynamic drag from its upright, boxy body.
At current fuel prices, a Nassau County buyer driving 15,000 miles annually will spend significantly more on fuel than a Rubicon V6 or 4xe PHEV driver. The 4xe (plug-in hybrid Wrangler) offers approximately 25 miles of electric range - enough for most daily Nassau County commutes - and its total fuel cost advantage over 3 years is meaningful for buyers who charge at home.
For buyers who make the 392 purchase, it’s typically because the V8 experience and sound are priorities that outweigh efficiency considerations. This is the correct way to evaluate it - as a performance vehicle with daily driver capability, not as a practical fuel choice.

For buyers considering the 4xe PHEV as an alternative, see how the two powertrains compare in a real-world cost analysis - the fuel savings over three years can be substantial for Nassau County commuters.
2-Door vs 4-Door 392
The Rubicon 392 is available in both 2-door (Sport) and 4-door (Unlimited) body styles. For Nassau County buyers, the Unlimited 4-door is the overwhelming choice - it has more rear legroom, a longer wheelbase for highway stability, and practical rear seating for passengers or cargo.
The 2-door 392 appeals to buyers who prioritize off-road agility above all - the shorter wheelbase improves the approach and departure angles in technical terrain, and the lighter weight contributes to better performance dynamics. For a street-and-trail balance, the 4-door is more practical.
The NHTSA safety ratings for the Wrangler reflect its body-on-frame construction - different from typical crossovers - and should be reviewed in context of the vehicle’s mission as an off-road capable truck.
FAQ
Is the Jeep Wrangler Rubicon 392 worth the price over a standard Rubicon? The 392 commands roughly a $25,000-$30,000 premium over a comparably equipped standard Rubicon. That premium buys the factory V8, factory warranty coverage for the engine swap, and the Xtreme Recon package option. For buyers who would spend $5,000-$10,000 on aftermarket V8 conversions anyway, the 392’s factory engineering and warranty make it the more rational choice despite the higher price.
How does the Rubicon 392 compare to the Jeep Wrangler 4xe? The 4xe prioritizes efficiency - approximately 25 miles electric range and significantly better fuel economy in hybrid mode. The 392 prioritizes performance - 470 hp and an unmistakable V8 sound. For Nassau County buyers who charge at home and use the Wrangler primarily as a daily driver with occasional off-road capability, the 4xe’s operating cost advantage is substantial over 3-5 years. For buyers who want the performance and sound character above all else, the 392 is the choice.
Can you daily drive a Wrangler Rubicon 392 in Nassau County? Yes - the Rubicon 392 is road-capable and comfortable enough for daily Nassau County driving. Seat comfort on the highway is adequate for commutes under an hour. The main challenges are fuel cost (13-17 MPG), somewhat rougher ride than a traditional crossover, and wider width with Xtreme Recon tires in tight parking situations. Buyers who have daily-driven previous Wranglers adapt quickly.
What trim packages are available on the 392? The Rubicon 392 is available in standard configuration and with the Xtreme Recon Package (35” tires, lifted suspension, 4.56 axle). Various option packages add features like Sky One-Touch power top, premium audio, and the Wrangler’s unique Easter egg design details. Ask Westbury Jeep about current configuration availability.
