Upgrade your truck’s performance with the RAS HD Suspension Kit—built for 1990–2024 Chevy Silverado and GMC Sierra 1500 models. Designed for drivers who tow, haul, and push their trucks to the limit, this heavy-duty system strengthens your factory leaf springs by up to 50% while delivering a smoother, more controlled ride.

Its progressive design provides added support under load while maintaining factory-level comfort when unloaded. Whether you’re towing an RV, hauling gear, or commuting daily, this 3-in-1 system improves stability, reduces squat, and enhances overall driving confidence.
