2020-2022 GM Duramax 6.6L L5P Helper Springs
If you tow and haul on a regular basis with your 2020-2022 GM Sierra/Silverado, you may have noticed some rear-end sag long before you hit your max payload rating. To help compensate for the heavy-loads you haul around, you can add a set of premium aftermarket helper spring to prop up your rear suspension for improved performance and appeal. These helper springs easily install onto your GM 2500/3500 truck, keeping your truck level and in control at all times. GM Duramax Fitments: 2020, 2021, 2022 GM 6.6L Duramax.
