What to Look For When Choosing the Best Shocks for Towing a Travel Trailer (Heavy Duty)?

  • Buy shock absorbers that can maintain the level height of your truck and has adjustable air pressure – preferably from 20 to 200 psi so that your truck can breathe easily. This adjustability is important because you can easily remove or add air according to your needs.

If it could maintain a ride height that could reach up to 1,100 lbs per pair, that is already exceptional.

  • With regards to the piston rod of the shocks, it should have a smooth chrome finish that is leak proof. It should be resistant to corrosion and also should be digressive and velocity sensitive. It reacts well to changing road and weather conditions but still gives you a smooth ride all the way through.
  • Your chosen heavy duty shocks should also offer full displaced valving which enables you to enjoy a smooth ride aboard your truck. It would also help if, for example, the shocks’ travel length is a little more than 9 inches, but it could have an extended length of up to 25 inches.
  • Its overall body diameter should be approximately 70 mm to show a robust look ideal for heavy loads and towing.

Overall, when all factors are considered, your chosen heavy duty shocks should have a long product life, have a consistent wear surface, and should also possess good seal lubrication.

  • Before buying heavy duty shock absorbers, be sure also that they are compatible with your own brand and make of truck. All the above features are a summary of ideal shocks for towing (heavy duty shocks).

Pro Tip:

Whatever heavy duty shocks you buy, make it a habit to always carry load or tow heavy
burden that’s UNDER CAPACITY of the maximum payload that your truck can carry. Even the best shocks for towing will break apart if you do not pay attention to the limits.

It’s very similar in features to the ACDelco 504-511 Air Lift Shock a Absorbers. They are both rear shocks but the 504-539 is $15 cheaper than 504-511. And both ACDelco shock variants appear in more than 2 million GM cars annually.

These shocks provide awesome handling for temporary situations, such as when your vehicle is towing a trailer or a boat or hauls a heavy load.

They also assist in the stabilization of the alignment angles, minimize suspension component wear, improve vehicle handling, and minimize the risk of bottoming out.

Do Heavy Duty Shocks Help With Towing and Heavy Load Duties?

Yes, they definitely do. Shock absorbers help with slowing down and controlling the movement of the vehicle. Keep in mind, truck’s rear leaf spring will have a key role under heavy loads or towing a trailer. Choose shocks that compromise between quality and price if you are on a budget.

Will Adding a Turbo Increase the Towing Capacity?

Putting in a supercharger turbo would help with towing by easing it and increasing the maximum amount that could be towed.

But it’s important that your truck’s drive chain could handle the extra load as well as your brakes.

So it’s also important that you elevate the braking abilities of your truck so it could handle the extra load.

But remember, an added turbo charge would mean something was added to the truck which was not designed within its specifications.

So, everything that will be affected by the increased load should be checked, not only the drive chain and the brakes. One thing that could happen is your engine could heat up from too much added pressure.

My Recommendation


This is hard. All the reviewed heavy duty shocks have their unique features. But it really depends on the brand and make of your truck because each of these shocks are not compatible with all brands. Take for example the 2 variants of ACDelco which are installed on almost all GM vehicles.

I like the fact that ACDelco advertises its 24 months, unlimited mile warranty. With this feature, it’s almost like advertising GM vehicles too.

I also admire those heavy duty shocks which could be inflated and deflated at will, depending on your requirements for your present load. All the brands, except for Bilstein are adjustable with air pressure in the heavy duty shocks. So choose among them.

Those shocks which have a distinctive difference between their collapsed length and full length have advantage over the other ones, because this would help a lot with heavy loads that the shocks won’t break because of the big allowance in compression. And Bilstein makes a big deal about this feature.

But what really stands out here is Rancho. It is a brand that doesn’t usually get recommended in regular size vehicles. But it gets a 5 star rating when it comes to heavy duty shocks.

Imagine, it’s the only nitrogen gas charged shocks in the group. They are not only self adjusting shocks but they also have reserve tubes which the other brands don’t offer.

I believe no other brand of shocks in the group offers this versatility.

So, the best shocks for towing are the Rancho RS999269 on my list, but check if it’s compatible with your vehicle. If your truck is a GM, go with ACDelco, because they’re trusted, partners.
