SuperSprings SSR-204-40 SumoSprings Solo Rear Helper Springs (Pair) | GM Trucks & SUVs

SuperSprings International SumoSprings Solo (Part Number: SSR-204-40) are patented, maintenance-free rear suspension helper springs engineered to upgrade and replace factory bump stops on select General Motors full-size SUVs, trucks, and commercial vans.

Key Features & Performance Benefits

• 1,000 lb Load Capacity: Rated for 1,000 lbs capacity at 50% compression to level rear-end sag when towing trailers or carrying heavy gear.
• Maintenance-Free Design: Self-contained micro-cellular urethane units require zero air lines, zero compressors, zero monitoring, and will never leak or rupture.
• Progressive Spring Rate: Soft initial engagement retains plush factory ride unloaded, progressively ramping up resistance as loads increase.
• Enhanced Stability & Control: Drastically reduces vehicle body roll, sway, and lane drift in crosswinds or emergency maneuvers.
• Direct Bolt-On / No-Drill: Bolts directly into existing OEM bump stop cups or factory mounting brackets using included hardware.
• Complete Axle Kit: Sold as a complete pair (left and right sides).
