Product description

The Weaver Oversize (OS) Short Control Core Kit is the ultimate "save" for worn-out oil control valve bodies on older in-ground lifts. When a standard valve core becomes too loose in its bore due to years of friction, the resulting internal bypass leads to cylinder drifting that standard seals cannot fix. This kit, referencing OEM number S-11116OSC, features an intentionally oversized aluminum core designed to create a tighter fit within a worn valve block. By using an OS core, shop owners can avoid the massive expense of replacing the entire cast valve manifold. This SVI International solution is a favorite among professional lift restorers working on Weaver and Rotary systems. It is manufactured in the USA with precision tolerances to ensure that even a veteran lift can operate with modern safety and stability.

Product highlights

• Problem Solver: Specifically engineered for valve bodies where the internal bore has become enlarged through decades of use.
• Restores Synchronization: A tighter core fit ensures that oil flow is accurately metered between cylinders for a level lift.
• Cost Effective: Allows for the repair of expensive control manifolds instead of requiring a full system replacement.
• Precision Machined: The S-11116OSC core is crafted in the USA by SVI to exact oversize specifications.
