What is included in a tow package?
In short, a tow package typically bundles the essential hardware and electronics needed to pull a trailer: a hitch assembly, trailer wiring, and a brake controller, with optional upgrades like enhanced cooling or suspension. The exact contents vary by vehicle and trim level.
What a tow package typically includes
Manufacturers assemble tow packages to prepare vehicles for trailer towing. Below are the components most commonly found across many pickups, SUVs, and crossover models. Some items may be standard, optional, or dealer-installed upgrades depending on the brand and model year.
- Hitch receiver and mounting hardware (commonly Class III or IV with a 2-inch receiver)
- Ball mount and hitch ball, plus a hitch pin and clip
- Trailer wiring harness and connectors (4-, 5-, or 7-pin, depending on needs)
- Towing electrical system including taillight converter and ground wiring
- Trailer brake controller (integrated into the vehicle or mounted as a portable/aftermarket option)
- Trailer stabilization features such as trailer sway control on supported models
- Engine and/or transmission cooling upgrades (e.g., transmission cooler) for heavier towing
- Upgraded suspension, springs, and/or shocks to better handle tongue weight
- Enhanced electrical capacity (e.g., higher-capacity alternator or battery protection) on some models
The exact mix varies; fewer basic packages may focus on the hitch and wiring, while higher-tier packages add braking, cooling, and suspension enhancements to support heavier loads.
Expanded options and factory vs. aftermarket differences
Some manufacturers offer modular tow packages or optional equipment like a dedicated engine cooling system, four‑wheel-drive towing modes, or a factory-installed trailer sway control. Others may rely on dealer-installed add-ons or aftermarket components. Always verify what's included for your exact vehicle and model year using the window sticker, the build sheet, or by asking the dealer.
How to verify what your vehicle’s tow package includes
To avoid surprises, confirm the precise contents of your tow package by checking official documentation and your vehicle's VIN-based build data. Below are the practical steps most buyers and owners take.
- Check the original window sticker or build sheet for towing equipment codes and options
- Review the owner's manual and the vehicle's multimedia interface for trailer integration features
- Ask the dealer or manufacturer for a detailed equipment list for your VIN
- Inspect the hitch area for a hitch receiver, wiring harness, and brake controller
- Test the trailer brake controller and have the wiring harness tested by a professional to ensure correct operation
Understanding your exact tow package helps you plan for compatible trailers, tongue weight limits, and any required maintenance or upgrades.
Why tow packages matter for towing performance
Tow packages aren’t just about pulling a trailer; they’re about maintaining control, braking power, and reliability under load. Vehicles with factory tow packages typically better handle tongue weight, offer safer wiring for trailer lights, and provide braking that compensates for trailer momentum. Always observe towing guidelines in your owner’s manual and consider professional installation for aftermarket additions.
Summary
A tow package standardizes the essentials for towing—hitch hardware, trailer wiring, and braking capability—with variations that can include upgraded cooling, suspension, and other support systems. The exact contents are model- and year-specific, so verify with the dealer or build documentation to ensure compatibility with your trailer and towing needs.
