The Grand Cherokee carries a genuine off-road pedigree that most Nassau County buyers never fully use — but should still understand. The difference between Quadra-Trac I and Quadra-Drive II isn’t marketing copy; it’s the difference between getting unstuck at a Hamptons beach parking lot and calling a tow truck.
Bottom Line: For most Long Island driving — snow, rain, gravel, and occasional beach access — Quadra-Trac II (standard on Limited and up) is more than sufficient. Quadra-Drive II with rear limited-slip differential is for serious off-road use.
- Quadra-Trac I: full-time AWD, no low range — great for snow and rain
- Quadra-Trac II: adds low-range 4WD and Selec-Terrain modes
- Quadra-Drive II: adds electronic rear limited-slip differential for true off-road
- Air suspension option (Overland+) adds 10” of ground clearance
The Three 4WD Systems Decoded
Jeep offers three distinct 4WD systems on the Grand Cherokee, each stepping up capability. Understanding which trim includes which system saves you from buying more (or less) than you need. For the full capability breakdown, see our complete Grand Cherokee guide.
Quadra-Trac I is the entry system, standard on Laredo. It’s a full-time AWD setup with a single-speed transfer case — no low-range gear, no driver-selectable modes. It handles rain, light snow, and slippery Nassau pavement effortlessly but cannot engage true 4-low for rock crawling or deep mud.
Quadra-Trac II upgrades to a two-speed transfer case, unlocking 4-low capability and the Selec-Terrain system. Standard from Limited trim upward, this system adds five terrain modes: Auto, Snow, Sand/Mud, Rock, and Sport. For Long Island’s occasional deep snow or North Fork vineyard back roads, this is the meaningful upgrade.
Quadra-Drive II tops the lineup on Overland and Summit. It adds an electronic rear limited-slip differential (ELSD) that can direct up to 100% of rear torque to a single wheel — the defining capability for serious off-road situations. Combined with Quadra-Trac II’s two-speed transfer case, it gives the Grand Cherokee genuine rock-crawling credentials.
| System | Trims | Low Range | Rear LSD | Best For |
|---|---|---|---|---|
| Quadra-Trac I | Laredo | — | — | Snow, rain, light unpaved |
| Quadra-Trac II | Limited, Altitude | ✓ | — | Most LI buyers, trails |
| Quadra-Drive II | Overland, Summit | ✓ | ✓ | Serious off-road, deep terrain |
Selec-Terrain: What Each Mode Actually Does
The Selec-Terrain rotary dial (Quadra-Trac II and up) adjusts throttle response, transmission shift points, stability control calibration, and torque vectoring for five distinct conditions:
Auto is the everyday default. The system continuously analyzes wheel slip and road conditions, seamlessly distributing torque without driver input. This handles Nassau’s wet roads and light snow without a second thought.
Snow reduces throttle sensitivity and shifts into higher gears earlier to minimize wheel spin. Engaged for Long Island winters, it prevents the unsettling rear-step that catches drivers on icy Hempstead Turnpike on-ramps.
Sand/Mud allows controlled wheel spin to maintain momentum through soft surfaces. The system tolerates longer slip events rather than immediately cutting power, which is what keeps you moving through Fire Island sand rather than digging in.
Rock locks the transfer case in low range, maximizes ground clearance sensors, and enables the hill descent control. Few Nassau County drivers will need this, but it’s there when a Catskill weekend gets adventurous.
Sport increases throttle sensitivity and delays transmission upshifts for a more engaged driving feel on twisty roads.
Air Suspension: The Ground Clearance Multiplier
The optional Quadra-Lift air suspension (available on Overland, standard on Summit) transforms ground clearance from 8.6 inches to 10.9 inches at maximum off-road height — among the best in the segment.
More useful daily: the suspension automatically lowers at highway speeds for better aerodynamics and can raise for loading and unloading. At the beach access ramp to Robert Moses State Park, a quick tap of the Off-Road 2 mode lifts the vehicle for the descent.
"People are surprised how capable these are even in street form. We get customers who use them at Jones Beach access points and the Pine Barrens — the standard Quadra-Trac II handles it without breaking a sweat."

Ground Clearance vs. the Competition
| Vehicle | Ground Clearance | Low Range | Terrain Modes |
|---|---|---|---|
| Grand Cherokee Limited | 8.6” | ✓ | 5 |
| Toyota 4Runner TRD | 9.6” | ✓ | 2 |
| Ford Explorer | 8.5” | — | 3 |
| BMW X5 | 8.7” | — | 5 |
| Grand Cherokee Overland (air) | 10.9” | ✓ | 5 |
Against the Ford Explorer — the most common family SUV comparison — the Grand Cherokee’s 4WD system is a generation ahead. The Explorer’s Intelligent 4WD offers no low range, one fewer terrain mode, and about 2 inches less effective clearance in rough terrain.

Frequently Asked Questions
Does the Grand Cherokee need special tires for off-road use? No — the standard all-season tires handle most Long Island terrain well. For true off-road use or frequent beach driving, all-terrain tires improve performance significantly.
Will the air suspension damage over time with regular off-road use? Air suspension is engineered for off-road cycles. Jeep’s Quadra-Lift system carries a standard warranty and has proven durable in real-world use. Avoid exposing air components to salt water immersion.
Can Laredo go off-road? Yes, Laredo’s Quadra-Trac I handles gravel, snow, and moderately unpaved roads well. It lacks the low-range and terrain modes of higher trims but is by no means road-only.
