Increasing Your Truck’s Towing Capacity
If your truck is rated to tow 8,000lbs. and you decide to sell your house, buy the biggest 5th wheel you can find and travel around the US with it, you may want to rethink that plan. That 5th wheel is going to be too heavy for your truck to tow. Yeah, it might physically pull the trailer down the road, but you’ll end up killing your engine and transmission, not to mention saying goodbye to any kind of decent gas mileage.
You just can’t increase the towing capacity on your truck more than what the manufacturer rated it for. There’s just no way to do that. From the engine and transmission to the frame and axles, these parts are there for a reason and are rated what they are to keep you safe. Half ton, three quarter ton and 1-ton trucks are all built differently. Different frames, suspensions, brakes, transmissions and a lot more critical components that are built with specifics in mind.
There are parts out there for towing that’ll help your truck out when pulling a load. There are beefy leaf springs you can add, air bag systems that’ll keep your rear end from squatting, heavy axles to hold the load better and big brakes to help you stop better. But these only make your truck’s job easier, they don’t make it possible to tow heavier loads than what it’s rated for.
What Could Happen?
So what could really happen if you pulled that too-heavy load? Well, nothing fun if that’s what you’re thinking. Pulling a giant boat with your half-ton truck? Yeah, may want to wear a life jacket when you back up into the water at the boat launch. Driving over 20mph pulling a too-heavy load? Hope you don’t need to stop in a hurry. You could literally kill someone.
There are only two solutions to towing a trailer or load that is heavier than what your truck is rated for: Get a bigger truck or pull a smaller load. Sorry to break it to you that way, but that’s the only safe way to do it. If you’ve got smart friends, ask the one with a degree in automotive engineering and physics and he’ll tell you. Don’t do it.
Ask you beer-drinking buddies (not automotive engineers) and they may tell you differently. The conversation would go something like, “Here’s what I did to my truck and I never had a problem”. Well, all we can say is, “just because it fits, doesn’t make is safe”. There are tons of ways to accessorize almost any aspect of a truck; whether it’s towing, lift kits or whatever category you choose. But are you willing to bet your life on taking advice from a non-professional?
If you do decide to take to life on the road with a big RV or camper, and your truck’s owner’s manual says it won’t pull that beast you want to haul, just go get a bigger truck.
