Product Description
SSR-207-47 Rear Helper Spring Kit for GM Heavy Duty Trucks
Stop Rear Sag, Eliminate Sway, and Tow with Confidence
Is your Chevrolet Silverado or GMC Sierra squatting dangerously low when you hook up your trailer? Do you feel every bump when your truck bed is loaded with gear? Factory suspension systems are designed for a comfortable ride when empty, but they often struggle under the heavy demands of towing and hauling.
The SSR-207-47 Progressive Rate Helper Spring is the ultimate solution for GM 2500HD and 3500HD owners. Unlike traditional steel add-a-leaf kits that make your ride harsh when empty, or airbags that require complex installation and maintenance, this micro-cellular urethane helper spring offers the best of both worlds: a smooth ride when unloaded and powerful, progressive support when you need it most.
✨ How It Works:
This unit replaces or supplements your factory jounce bumpers. When your truck is empty, the spring remains inactive, preserving your factory ride quality. As you add load and the suspension compresses, the SSR-207-47 engages progressively, providing increasing resistance to prevent bottoming out and maintain optimal ride height.
🌟 Key Features & Benefits:
Perfect Compatibility: Fits 2001-2019 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD.
Fits: 2001-2006 (GMT800), 2007-2014 (GMT900), 2015-2019 (K2XX) Heavy Duty Models.
Requirement: Must have factory leaf spring rear suspension.
Progressive Load Support: Provides variable resistance. Light loads = soft ride. Heavy loads = firm support. No more harsh, bouncy rides when the truck is empty.
Silent Operation: Made from advanced urethane compound that absorbs vibration and noise. Say goodbye to the metallic clunks and squeaks common with steel helper springs.
Built for Extremes: Impervious to road salt, mud, oil, and UV exposure. Performs consistently in freezing winters and scorching summers without cracking or degrading.
Safety First: Keeps your truck level, ensuring proper headlight alignment and balanced braking distribution when towing heavy campers, boats, or equipment.
🔧 Installation Overview:
Lift Vehicle: Safely raise the rear of the truck and support it on jack stands. Remove the rear wheels for easier access.
Locate Bumper: Identify the factory jounce bumper located above the rear axle on the frame or within the leaf spring pack.
Remove Old Part: Unbolt or pry out the worn factory rubber bump stop.
Install SSR-207-47: Position the new helper spring into the mounting location. Secure with provided hardware (or reuse factory bolts if applicable).
Test: Lower the vehicle and test with your typical load. You will immediately notice reduced sag and improved stability.
