1998-2016 F150-F350 & 2011+ GMC 2500/3500 SULASTIC SHACKLE FOR REAR AXLE

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.
