Looking for rear shocks that help with towing.

Jeff Bryer · March 18, 2022

I used Monroe Shocks & Struts Load Adjusting 58654 Shock Absorber on a 2015 GMC not sure if same part number. Anyway looking online one article states these will work. But when search online they say they won't, not sure if they will fit. Like how they help with sag and add a extra inch to back height. Looking to find out of these will fit or another brand that made for help in towing/sag and possibly add a inch to rear height

Helper bags is all I ever suggest to people, they work so much better for heavy towing.

Understand but was really hoping to not go airbag. The load Adjusting shocks worked great on my 2015 GMC. Raised the back end up about 1 inch and much less sag truck stayed pretty level and handle well. I tow 4000 lbs 90% time and 7000lbs about 4 or 5 times a year.

The shock mounts aren't made for supposrting weight.

If you want more height use a block, add a leaf, or spring pack. If you want more load stability use a bag setup or something like Timbrens or SumoSprings.

I had 2 Air Lift bags with a compressor installed on my ‘21 Silverado. It came with a remote fob to adjust the air pressure. I tow a 32 ft RV and an open air car trailer. I love the system. It’s there when I need or just along for the ride when I don’t. $1500 installed which I didn’t think was too bad for the assurance I get. They really took care of any trailer away I had before the bags where installed.

I am using SuperSprings. They are like adding a leaf spring. They lift the rear end up and help with body roll. I tow about 8,000 lbs. all summer and winter. So far I am liking them. I did not notice any negative ride quality while not towing.

If your tongue weight is so much that you get sagging in the rear, you need a load equalizing hitch such as an Easy-Lift. Your owners manual should give you your tongue weight limit.

I've got an Equalizer hitch and only towing 4000 lbs and 350lb tongue weight and my back end sags. I have the tow package, and off road package . No adjustment on the hitch has been able to reduce it.

For squat I would go with a Deaver leaf spring pack. Airbags are another option if its in your budget. If you want to change the shocks, Eibach and Bilstein are your two best options.

My problem is not sag, I am get a seesaw effect when hooked to the trailer on roads with waves. I am looking for a strong shock to stop that effect.

Are you referring to porpoising? Yes, firmer shocks will help with that. Last truck, an '18, had Eibach Pro Truck Sport shocks installed in the rear. Huge difference! Not to expensive. There's probably better but they simply worked. New truck, a '23, is bouncing all over the place. We're on a camping trip right now but I'm replacing the OEM Ranchos as soon as we get home.

Are you using a weight distribution hitch? Some 'bounce' more than others

Yes, I am using an 'Equilizer' brand hitch. Formally pulled the trailer with a '19 RAM 1500 and did not have this issue, traded truck because it didn't have enough horses for this trailer. This Sierra 4x4 at stock height was 'porpoising' on it's maiden pull, would like to get this corrected, looking for recommendations.
