THE 2027 EQUIPMENT GUIDE · JEEP & RAM
New model year.
Which 4×4 system?
Shopping a 2027 Jeep or RAM? An automatic mode, low range and axle locks are three separate questions. Here’s what the documented examples tell us—and what still needs checking.
Inside this guide
01 / THE USEFUL ANSWER
2027 is a year. It isn’t an equipment list.
A newer vehicle can have different drivetrain equipment. It can also offer several systems within the same model year. Compare the installed system before treating a year change as a capability upgrade.
Our AWD-versus-4WD field guide explains the operating concepts. This companion answers a narrower shopping question: what should you verify when comparing a remaining 2026 vehicle with a 2027 Jeep or RAM?
The evidence does not establish a universal 2027 drivetrain change across both brands. It does establish useful examples of why a shopper needs more detail: Wrangler’s part-time and full-time choices, and RAM’s announced Rumble Bee application. The conclusion belongs to the specific configuration.
02 / THE EVIDENCE DESK
Three examples. Three different limits.
Choose a source-backed example. The distinction between a documented feature and an unanswered equipment question is part of the comparison.
OWNER’S MANUAL · EQUIPPED EXAMPLE
2026 already requires a system-specific comparison.
The cited Wrangler manual includes a five-position transfer case with 4H AUTO as well as other configurations. The cited RAM manual documents an equipped on-demand system. “Automatic operation” is not automatically a new-for-2027 feature.
It does not identify the equipment on a particular 2026 vehicle or prove that an entire 2027 lineup is unchanged.
Ask for the installed controls and the matching manual for both vehicles.
03 / 2027 JEEP WRANGLER
“Rubicon” still leaves a question.
Jeep’s 2027 capability information describes Command-Trac as part-time and Selec-Trac as an available full-time system. It also distinguishes standard part-time Rock-Trac on Rubicon and Rubicon X from an available full-time Rock-Trac configuration.1
That gives a shopper a concrete question to ask even after choosing a trim: which transfer case does this vehicle actually have? A desirable trim badge is useful context, but it does not replace equipment verification.
Command-Trac
Jeep lists a 2.72:1 low range. Check the installed system and its mode instructions.
Selec-Trac
Jeep describes automatic engagement. Confirm availability and equipment on the exact vehicle.
Rock-Trac
Jeep lists part-time and available full-time variants, with a 4:1 low range in its description.
These are system descriptions, not a complete order guide. They do not confirm every engine, transmission, package or trim combination. For a vehicle you are considering, pair the equipment information with its controls and applicable manual.
Compare the system within the trim—not just the trim within the year.
04 / 2027 RAM 1500
A new application isn’t a rule for every truck.
RAM’s official Rumble Bee announcement describes active full-time four-wheel drive with variable torque distribution, using a BorgWarner 48-11 transfer case. It also describes a separate rear-wheel-drive control.2
This is a useful 2027 example because it asks you to read the system’s purpose and controls. It does not establish that every 2027 RAM 1500 uses this architecture. Nor does the full-time description, by itself, establish low range.
Keep the announcement in its proper lane. It is manufacturer launch information, not a verified Bonham vehicle, delivery promise or owner’s-manual procedure.
Before comparing it with another RAM, confirm the exact model, equipment, current availability and applicable operating documentation. Do not transfer these features to a Tradesman, Laramie, Rebel or RHO without supporting evidence.
For the broader 2027 RAM 1500 range, we have not verified a complete U.S. transfer-case matrix against an owner’s manual or order guide. That remains an open equipment check. A blank in that matrix is a reason to ask for evidence.
05 / THE YEAR-OVER-YEAR CHECK
What can we actually compare?
| Shopping question | 2026 reference | 2027 reference / next check |
|---|---|---|
| Automatic mode? | The cited Wrangler and RAM manuals document equipped automatic-mode examples.3 | Jeep documents full-time choices. Confirm the installed system on each vehicle; do not assume a new benefit from the year alone. |
| Low range? | The cited equipped manual examples include low-range positions. | Jeep publishes low-range descriptions for named Wrangler systems. Verify the actual configuration; do not infer low range on an announced RAM application. |
| Axle locks? | Axle equipment is separate from the transfer-case mode. | Ask about the fitted front and rear axle equipment independently. An all-four-wheel-drive label does not answer this. |
| Better value? | Compare the actual vehicle, condition, equipment and written transaction terms. | Use the same requirements and price assumptions. Neither the badge nor the year establishes the better purchase. |
Give each candidate the same job description. For paved commuting, note the pavement-compatible mode. For genuinely difficult low-speed access, note the verified gearing, tires and clearance. For towing, perform a separate exact-vehicle loading and ratings check.
A useful conclusion can be “these vehicles have the same feature I need,” “this one adds a verified capability,” or “we still don’t know.” There is no need to invent a difference to justify comparing them.

07 / QUESTIONS, ANSWERED
Before the year becomes the deciding factor.
Is every 2027 4WD system different from 2026?
We have not established that. Compare documented equipment on the actual candidates. An announced 2027 application or a changed trim offering does not prove that every system changed.
Does a 2027 Rubicon always have full-time 4WD?
Jeep’s cited 2027 description distinguishes standard part-time Rock-Trac from an available full-time variant on Rubicon and Rubicon X. Confirm the exact vehicle’s configuration.1
Can I use a 2026 manual to operate a 2027 vehicle?
This guide’s 2026 references establish a baseline for comparison. Use the correct operating documentation for the actual 2027 vehicle and installed system; do not transfer shift instructions from a general comparison.
Does newer 4WD mean safer braking in bad weather?
A newer model year or drivetrain badge is not a stopping-distance guarantee. Tires, conditions, speed and spacing still matter. Review the limits explained in the main AWD/4WD guide.

RESEARCH & TRANSPARENCY
What we checked. What remains open.
Developed with AI assistance for research, drafting and layout, for Bonham Chrysler. This is a sourced shopping guide, not an instrumented road test or exact-VIN inspection. We have not verified a complete 2027 U.S. owner’s-manual/order-guide matrix. That evidence gap is stated explicitly; it does not prove the documents are unavailable.
