SAJ-03F Adjustable Sulastic Shackle for Rear Axle

SKU: SAJ-03F
$990.00

The SAJ-03F adjustable sulastic model is:

- Flexible on load working range up to the truck’s GVWR because it can be adjusted on the limit stops by only using a wrench if it is required.

- Used when the truck is constantly under heavy loads and/or for long periods and/or the truck’s CURB weight has been modified by removing or adding weight to the bed as per example: camper, heavy tool boxes, compressors, etc.

- When the user is looking for a long-lasting part under extreme load and/or weather conditions.

- Best vibration and shock absorption because it has at least 2 times the mass of rubber than the preloaded model.

- Best lateral control because the forces are distributed on a bigger mass of rubber.

===SULASTIC IMPROVES: ===

- Smooths out the ride by just replacing the OEM shackle

- Reduce Vibration and Shocks Not Absorbed by the Leaf-springs

- Stops the Bed Bouncing

- Improve Stability

- Reduce Braking Distance

- Load & Towing Capacity Not Affected

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%

TEST DODGE AND CHEVROLET OEM SHACKLE

VS SULASTIC SHACKLE  

 

The following photo shows how the pick-up works without sulastic marked in blue and with sulastic marked in pink at the frame and the cab. This shows us that sulastic works within a range of plus or minus 0.2 average during the test time while the OEM shackle receives the direct impacts and is transmitted to the frame and the driver. If you want to see all the information, please visit our SULASTIC MEDIA REVIEWS

 

 SULASTIC SHACKLE VS OEM SHACKLE

The graphs show that the vibration is less in the sulastic shackle than in the OEM shackle. The SAJ-03F model has better vibration and shock absorption because it has at least 2 times the rubber mass of the preloaded model.
