2007.5-2010 GM Duramax 6.6L LMM Helper Springs
The 2007.5-2010 GM 6.6L Duramax LMM is certainly no slouch when it comes to towing and hauling, but even the toughest GM 2500/3500's will start to sag well before you hit it's GCWR or GCWR. When this inevitably happens, choose a set of premium helper springs to help keep your truck level in even the most aggressive situations. These helper springs are premium towing upgrades designed to help prevent rear-end sag, sway, body roll, and general instability when your truck is loaded down.
