  • 【Superior 1,400 lbs Load Support】 Eliminate rear end sag and bottoming out when hauling heavy cargo or towing a trailer. This rear suspension helper spring kit provides up to 1,400 lbs of additional load support, leveling your vehicle and restoring proper suspension stance. Designed for heavy duty use, it ensures your 4Runner or GX460 maintains stability and control under maximum load capacity without compromising the factory ride quality.
  • 【Maintenance-Free Microcellular Urethane】 Unlike air bags that require compressors, airlines, and are prone to leaks, these helper springs are completely maintenance-free. Constructed from durable, closed-cell microcellular urethane, they are puncture-proof and impervious to harsh elements. This solid construction guarantees reliable performance for the lifetime of your vehicle without the need for adjustments or upkeep.
  • 【Progressive Spring Rate for Comfort】 Experience a smooth, comfortable ride whether your vehicle is empty or fully loaded. The advanced SumoSprings material features a progressive spring rate that compresses gradually. It acts as a dynamic bump stop, engaging only when needed to absorb harsh road impacts and vibrations, then recovering with full memory rebound to return to its original shape.
  • 【Direct Bolt-On Replacement】 Simplify your suspension upgrade with a straightforward installation. This kit is a vehicle-specific, direct bolt-on replacement for your original rear bump stops. All necessary hardware is included, allowing for a quick installation with basic hand tools. No special drilling or modifications are required to fit your specific Toyota or Lexus model.
  • 【Enhanced Towing and Hauling Control】 Regain confidence when towing your boat, camper, or tackling uneven terrain. By reducing dangerous body roll and trailer sway, these suspension enhancements significantly improve handling and braking response. The increased stability provides a safer, more controlled driving experience in all scenarios, from daily driving to heavy duty hauling.
