Timbren GMRTT15S is a rear SES severe-service suspension enhancement kit using Aeon rubber springs to help manage load-related sag, sway and body roll.
How it works
- Progressive spring resistance increases as the load grows, adding support when it is needed.
- Rubber spring system does not require air-pressure adjustments.
- Single-convoluted severe-service springs provide firmer support for top-heavy loads such as truck campers.
