Stellar 1099 Bobalee Seal Kit for 2.00-Inch Hydraulic Cylinders

If you’re unsure whether this part is compatible with your truck or equipment, please contact us to confirm fitment before purchasing.

The Stellar 1099 Seal Kit is a genuine OEM hydraulic-cylinder repair kit designed for compatible 2.00-inch Bobalee cylinders used on Stellar equipment. It supports cylinder part numbers 3783, D0773, C4789, C5421, 19507, 51344, and 51819.

If the cylinder leaks hydraulic fluid, drifts under load, loses pressure, or operates inconsistently, the Stellar 1099 provides the replacement sealing components required to rebuild a compatible cylinder. Installing new seals can restore hydraulic performance without replacing the complete cylinder when its structural components remain serviceable.

What This Part Is Used For

The Stellar 1099 seal kit replaces worn internal seals in compatible 2.00-inch Bobalee hydraulic cylinders. The seals help contain hydraulic fluid, maintain pressure, and prevent internal bypass during cylinder extension and retraction.

Common Reasons For Replacement:

Hydraulic fluid leaking around the cylinder rod
Cylinder drifts or will not hold position
Loss of lifting or holding power
Internal hydraulic bypass
Jerky or inconsistent cylinder movement
Seals damaged by heat, age, or contamination
Cylinder requires rebuilding during scheduled service
