2017-2022 Ford F-250/F-350/F-450 Adjustable Sulastic Shackle for Rear Axle

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
