Timbren Industries GMRCK35MA SES Suspension Enhancement System - Kit

The Timbren Industries GMRCK35MA SES (Suspension Enhancement System) is a heavy-duty rubber spring suspension upgrade designed to provide progressive load support for trucks during towing and hauling operations. This bolt-on system replaces traditional bump stops with hollow rubber springs that engage gradually under load, delivering a smoother ride quality compared to air bags or leaf spring helpers.

Key Features:

• Hollow rubber spring design provides progressive load support that engages automatically when needed
• No maintenance required—no air lines, compressors, or adjustments needed
• Installs in place of factory bump stops using existing mounting points
• Reduces body roll, sway, and rear-end squat when loaded or towing
• Improves steering control and braking performance under load
• Constructed from durable Aeon rubber compound for long-lasting performance
• Lifetime warranty against defects in materials and workmanship

The SES system works by compressing progressively as load increases, providing support exactly when and where it's needed without affecting unloaded ride quality. When not under load, the hollow springs remain inactive, maintaining factory ride comfort. Installation typically requires basic hand tools and can be completed in approximately one hour without drilling or modifications.
