SuperSprings Rear SumoSprings for Silverado/Sierra 2019-2025 (New Body Style) — 1000 lb Capacity, Progressive Polyurethane

If your New Body Style Silverado or Sierra 1500 feels lower in back when towing or hauling, these rear SumoSprings offer a maintenance-free way to regain ride height and control without compressors, airlines, or complicated hardware. Designed to replace the factory bump stop location, the one-piece closed-cell microcellular polyurethane springs compress progressively as load increases, delivering extra support up to 1000 lb at 50% compression while smoothing impacts and reducing sway.

How do SumoSprings help when I tow or haul heavy loads?

SumoSprings add progressive resistance as weight is applied, which limits rear-end sag and improves tow angle and braking balance. Because they compress gradually, they provide support only when needed, preserving normal ride quality when the bed is empty.

• Supports up to 1000 lb at 50% compression for trailer and cargo loads
• Reduces rear squat to help keep headlights and hitch alignment correct
• Dampens impact and minimizes trailer sway for steadier handling

Are these complicated to install or maintain?

Installation is straightforward: SumoSprings seat where the factory bump stop sits, so no airlines, compressors, or wiring are required. They are a plug-and-play upgrade that needs no ongoing adjustment or seasonal maintenance.

• Installs in the rear bump-stop location — simple bolt-in fit
• No air system, seals, or compressors to monitor or repair
• Lifetime warranty and weather-resistant material reduce upkeep

Will these change ride comfort when I’m not carrying weight?

Because SumoSprings are progressive, they compress minimally with light loads and remain soft at rest, preserving factory ride comfort on everyday drives. Comfort only gives way to firmer support as payload increases, so you get a balanced ride in most conditions.

• Microcellular polyurethane remains compliant with light or no load
• Progressive compression provides a smooth transition to firm support
• Helps control body roll and harsh bottoming under heavy loads

What makes these SumoSprings durable for long-term use?

Constructed from closed-cell microcellular polyurethane, SumoSprings resist moisture, UV, corrosion, and extreme temperatures that commonly degrade suspension components. Their solid design eliminates moving parts and air leaks, delivering consistent rebound and long service life backed by SuperSprings' lifetime warranty.

• Closed-cell polyurethane resists water, salt, and UV damage
• No metal-on-metal wear points or compressors to fail
• Engineered to maintain support and rebound mile after mile
