Every truck owner knows the struggle. You hook up a heavy trailer, and your rear end sags. Your headlights point skyward. Your ride turns rough, and braking feels unpredictable. Tow Assist Air Bag Kits solve all of that, fast, affordably, and without permanent modifications. 

At True Suspension, we have spent years perfecting air ride solutions for trucks, SUVs, and work vehicles. Our kits are trusted by thousands of drivers across the country. Whether you haul heavy loads weekly or tow a camper on weekends, our tow assist air bag kits deliver the performance and confidence you deserve. 

What Are Tow Assist Air Bag Kits?

Tow Assist Air Bag Kits are aftermarket suspension upgrades that add inflatable air bags (also called helper air springs) alongside your existing leaf or coil springs. When you load your truck or hitch a trailer, you inflate the bags to support the extra weight. When you're driving unloaded, you deflate them for a comfortable stock ride. 

These kits work on a simple principle: air pressure equals load support. More pressure handles more weight. It's adjustable, repeatable, and completely under your control.

True Suspension's tow assist suspension kits include everything you need: air bags, brackets, airline fittings, and in-cab controls. You get a complete system, not just parts. 

Metric	Data

Average sag reduction	90%+ elimination of rear end droop
PSI range for most kits	5 – 100 PSI adjustable
Installation time (average)	2 – 4 hours

Why Your Truck Needs a Tow Assist Air Bag Kit?

Most trucks leave the factory with springs rated for average loads. The moment you add payload or tow heavy, those springs hit their limit. The results are dangerous: 

• Rear end sag shifts weight distribution
• Headlights aim upward and blind oncoming drivers
• Braking distance increases under load
• Tire wear accelerates unevenly
• Steering feels vague and disconnected 

Our tow assist air bag suspension kits fix all five of these issues. You stay level, steer straight, brake safely, and protect your tires, all with a kit that installs in your driveway.

How to Choose the Right Tow Assist Air Bag Kit?

Selecting the right tow assist air bag kit comes down to four factors: 

1. Your Vehicle Year, Make, and Model

Our kits are vehicle-specific. A kit built for a 2015 F-250 4WD won't fit a 2010 Ram 2500 2WD. Always confirm your exact year and drivetrain before ordering. 

2. Your Suspension Type

Leaf spring trucks use one style of air bag mount. Coil spring trucks use another. True Suspension lists both options for all major platforms. 

3. Your Load Requirements

Light haulers may only need a basic helper kit. Heavy commercial haulers should look at our max-capacity kits for 2500 and 3500 HD trucks. 

4. Your Control Preference

Do you want in-cab controls, or will a manual Schrader valve fill point work for you? We offer both. Our in-cab air management systems are the popular choice for frequent towers. 

Universal Tow Assist Air Bag Kits for Any Build

Not every truck fits a vehicle-specific kit. That's why True Suspension offers universal towing assist air ride suspension control systems that work across multiple platforms. 

Our universal kits include: 

• Dual-switch control panels for independent left/right adjustment
• Single-switch panels for simple inflate/deflate setups
• Manual toggle valves for budget-conscious builds
• Air hose push-in fittings in 1/4" and 3/8" sizes
• Active fill valves with Schrader connectors 

These components let you build a custom tow assist system for classic trucks, hot rods, and commercial vehicles that don't have a dedicated kit. 

Installing Your Tow Assist Air Bag Kit: What to Expect

Most of our customers install their tow assist air bag kits in an afternoon. You don't need a lift or special tools for most applications. 

Typical installation steps: 

• Step 1: Remove the rear wheels and locate the leaf spring or coil spring
• Step 2: Install the lower bracket on the axle housing
• Step 3: Mount the upper bracket to the frame
• Step 4: Seat the air bag between the brackets
• Step 5: Route the airline from the bag to your control valve or panel
• Step 6: Mount the in-cab control panel (if included)
• Step 7: Inflate to 20–25 PSI and check for leaks 

Each True Suspension kit ships with detailed instructions and all hardware. If you ever have questions, our support team is ready to help. 

Real-World Performance: What Our Customers Report

Data from customer feedback and field testing shows consistent results across our tow assist air bag suspension kits: 

Performance Metric	Before Kit	After Kit
Rear sag at max load	3–5 inches of droop	Less than 0.5 inches
Headlight aim change at load	4–6 degrees upward	Less than 1 degree
Driver confidence rating (1–10)	5.2 average	9.1 average
Steering feel under load (1–10)	5.8 average	8.7 average
Ride quality when empty (1–10)	8.5 average	8.4 average (no loss)

Notice the last row. Tow assist air bag kits do not sacrifice your everyday ride. When you're driving unloaded, you simply deflate the bags and return to factory comfort. 

Combining Tow Assist Kits with Lift and Leveling Upgrades

Many truck owners pair their tow assist air bag kits with leveling or lift kits for a more capable build. A leveling kit corrects front-to-rear rake. Air bags handle rear sag under load. Together, they create a truck that looks great and hauls confidently. Learn more by reading our guide on lift kits vs. leveling kits: what truck owners must know. 

True Suspension carries both. Browse our full catalog of Pro Comp ES9000 nitro-charged shocks, torsion key kits, strut spacers, and lift blocks that pair perfectly with your air ride towing system.

Rubber Block vs. Air Ride, Making the Right Call

Some truck owners ask whether a rubber spring block insert is cheaper and just as effective. The honest answer: it's not. Rubber blocks offer a fixed resistance that you can't adjust to match your load. Tow assist air bag kits let you dial in the perfect pressure for every load. Read our full comparison in our guide on rubber block vs. air ride suspension, which is best for you. 

The choice is clear when you see the data. Adjustable air support wins on performance, flexibility, and long-term value. 

Maintaining Ride Quality After Your Kit Install

One concern we hear often: "Will my ride get rough after the install?" Not with our kits. Tow assist air bag kits from True Suspension are tuned to leave your empty-truck ride completely unchanged. When unloaded, run 5–10 PSI in the bags. Your stock springs carry the truck as they always have. For tips on keeping that factory feel, see our guide on the top 10 ways to maintain factory ride quality after installing a lift kit. 

Complete Your System with True Suspension Accessories

A great tow assist air bag kit deserves great accessories. True Suspension carries a full range of complementary hardware: 

• 1/4" and 3/8" push-in air hose fittings, for leak-free connections
• Active Air compact compressors, 1.3 HP, 100% duty cycle
• 4-corner air ride manifold blocks, for FBSS builds with 4 or 8 valves

Frequently Asked Questions 

Q1. What is a Tow Assist Air Bag Kit and how does it work?

A tow assist air bag kit installs air springs beside your factory springs. Inflate them when hauling to level your truck and increase load support. Deflate when empty for stock comfort. 

Q2. Will a tow assist air bag kit damage my factory suspension?

No. Our kits mount alongside existing springs without replacing them. They add support without removing or altering any factory component. Your warranty on OEM parts is unaffected. 

Q3. Can I install a tow assist air bag kit myself?

Yes. Most installs take 2–4 hours with basic hand tools. True Suspension kits include all hardware and instructions. No welding or cutting is required on most truck applications. 

Q4. How much weight can a tow assist air bag kit support?

Depending on the kit, our tow assist air bag kits can add up to 5,000 lbs of additional load-carrying support. Check your specific vehicle kit page for rated capacity details. 

Q5. Do I need a compressor or air tank to run the kit?

Not necessarily. Many of our kits are tankless. You fill the bags with a portable inflator or Schrader valve. Upgrading to an onboard compressor is optional for maximum convenience.
