Description
Description
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
