Buying Guide: What to Look For in the Best Rear Shocks for Towing on the 2015 F150
When I started looking for the best rear shocks for towing on my 2015 F150, I quickly realized it wasn’t just about picking the most expensive option. It’s about finding the right tool for the job. Your truck’s factory shocks are designed for a comfortable ride when it’s empty. But hook up a heavy trailer, and they can feel overwhelmed, leading to sagging, bouncing, and a general lack of control. Upgrading your shocks is one of the most effective ways to reclaim that stability and safety.
The first thing I consider is the shock type. You have a few main choices. Monotube shocks are my go-to for serious towing. They dissipate heat better than twin-tube designs, which is crucial because heat is the enemy of shock performance. When you’re hauling a heavy load for miles, your shocks get hot. If they overheat, they fade and stop working effectively. A monotube shock handles this much better, giving you consistent damping when you need it most. Twin-tube shocks can be a good budget-friendly option for lighter loads, but for heavy-duty towing, I lean towards monotube.
Next, I look at the valving. This is the internal system that controls how the shock fluid flows, determining how firm or soft the ride is. For towing, you want a shock with firmer valving. This controls the suspension movement more aggressively, preventing the excessive bouncing and sway that can happen with a trailer pushing you around. Some shocks are adjustable, which is a fantastic feature. You can dial in the firmness for when you’re towing and then back it off for a more comfortable ride when you’re unloaded. It’s the best of both worlds.
Finally, don’t forget about the physical construction. A larger bore diameter generally means more fluid and more consistent performance. I also check what the shock body is made from; a hardened, polished steel body resists pitting and corrosion from road salt, which is important for longevity. The goal is to find a shock that’s built tough enough to handle the constant stress of towing without wearing out prematurely. Getting the right set of rear shocks for towing on your 2015 F150 makes a world of difference, turning a white-knuckle drive into a confident, controlled journey.
Frequently Asked Questions
Do I need to replace my front shocks when I replace the rears for towing?
While your primary focus for towing improvement is on the rear, I highly recommend replacing the front shocks at the same time if your budget allows. Your truck’s suspension works as a complete system. Worn-out front shocks can contribute to nose-diving during braking and overall instability, which is only magnified when you have a trailer attached. For the most balanced and controlled handling, a full set of four matched shocks is the way to go.
Can I install new rear shocks myself, or do I need a professional?
If you’re comfortable with basic hand tools and have a safe way to lift and support your truck, installing rear shocks is a very doable DIY job. You typically only need a socket set and some penetrating oil to loosen the old hardware. However, the bolts can be seized from rust, which is the biggest challenge. If you’re not confident or run into a stubborn bolt, there’s no shame in taking it to a professional mechanic. The job is relatively quick for them, so labor costs shouldn’t be too high.
Will upgrading my shocks increase my truck’s towing capacity?
This is a crucial distinction to make: no, upgrading your shocks will not increase the official maximum towing capacity of your 2015 F150. That rating is determined by the manufacturer based on the engine, transmission, frame, brakes, and axle. What better shocks do is dramatically improve your truck’s ability to handle weight within its rated capacity. They control the suspension, reduce bounce, and improve stability, making towing much safer and more comfortable up to your truck’s limit.
How often should I replace the rear shocks on my F150 if I tow frequently?
If you do a lot of towing, you’ll be putting extra strain on your shocks, and they will wear out faster than on a truck that never tows. While there’s no single mileage number, I start paying close attention to how my truck feels after 40,000 to 50,000 miles of mixed use with towing. Signs you need new shocks include excessive bouncing after a bump, a shaky feeling in the rear end when towing, or visible fluid leaks on the shock body. It’s not a bad idea to have them inspected annually if you’re a heavy tower.
What is the difference between standard and “load-adjusting” shocks?
Standard shocks have a fixed damping rate. Load-adjusting shocks, like some air-assisted or progressive-valve models, are designed to change their characteristics based on the weight they’re supporting. As the load increases, they automatically become firmer. These can be an excellent choice if your towing or payload weight varies significantly from trip to trip. They help maintain a more level ride height and consistent handling whether you’re empty or hauling a heavy load, making them a smart pick for finding the best rear shocks for towing on the 2015 F150.
