WHAT IS SULASTIC RUBBER SPRINGS?

 

Sulastic is a suspension system designed to improve a vehicle's ride quality and handling, particularly in pick-up trucks and heavy-duty vehicles. The key component of the Sulastic suspension system is the Sulastic shackle, which replaces the traditional leaf spring shackle found in many suspension systems.

The primary purpose of the Sulastic suspension system is to reduce the transmission of road vibrations and shocks to the vehicle chassis and cabin. This helps provide occupants with a smoother and more comfortable ride and reduces wear and tear on the vehicle’s components.

The Sulastic shackle typically consists of a central pivot point with elastomeric elements on either side. These elastomeric elements act as shock absorbers and allow for a certain degree of movement and flexibility in the suspension system, improving the vehicle's ability to absorb road imperfections and providing a more controlled and comfortable ride. 

Sulastic suspensions are often used in pick-up, heavy-duty trucks, RVs, and other commercial vehicles where ride comfort is important. They help reduce driver fatigue and improve overall vehicle stability. 

 

FEATURES & BENEFITS: 

  • Reduce Vibration and Shocks 60-80%
  • Improve Stability 20-30%
  • Reduce Braking Distance 10-20%
  • Stops the Bed Bouncing
  • Reduce the impact harshness over potholes & broken pavement
  • The joints at the concrete roads produce picky noise, this noise is gone when you install the sulastic.
  • Smooth out the ride by just replacing the OEM shackles.
  • Load and towing Capacity Not Affected
  • Improves Handling and Control of the Vehicle
  • Quality ride improvement in rainy, cold & hot weather
  • Requires no maintenance.
  • Set includes 2 sulastic shackles per axle.

Lasted 11 years... Time for a new set.

Originally installed in 2012 and the GMC Sierra 2500HD rode much better.   Noticed lately the bed jumping around quite a bit.   The rubber bushings have worn out and the shackles are sitting on the over rotation stops.   Time for a new set.   Worth it to make the 2500 ride a little better.

These did not disappoint.  Night and day difference for me. I look forward to driving that truck now.
