Timbren Suspension Kits (SES Kits) are designed to enhance the suspension of your vehicle.
  • Easiest to Use: Rubber cushions absorb road shocks and automatically adjust to uneven loads or road conditions.
  • Easiest to Maintain: There are no airlines or fittings to allow leaks. Simply bolt the kit on and you are set for a lifetime of trouble-free suspension.
  • Easiest to Install:  There are no holes to drill, no airlines to route and SES Kits can be installed in a matter of minutes using basic hand tools.
The softer ride quality of today's trucks and the mediocre suspensions found on most trailers can cause excessive trailer sway, instability and suspension settling.

Timbren SES Suspension Enhancement Systems are highly recommended by professionals and governments for all snow removal equipment to get the job done...

How can Timbren offer you the best of both worlds...?

• Extra capacity when the plow is mounted
• A smooth ride at all times

When the snowplow is installed, powerful Aeon® hollow rubber springs progressively carry the additional weight, preventing spring sag and bottoming out.

The design of the Timbren kit and the progressive rate of the Aeon® spring mean that there is no interference with the normal activity of the suspension when the snowplow is removed.

  • Since the Aeon® hollow rubber springs carry most of the added load, your truck suspension will last longer.
  • Reduced maintenance costs and less downtime are particularly important to snowplow operators.
  • Eliminate the high cost and harsh ride caused by adding leaf springs or helper springs to carry rear mounted/top heavy spreaders.
  • Timbren has a complete line of front and rear suspension stabilizer kits.
