Detailed Description

SKF Speedi-Sleeve 99452 is used to restore shafts that have been scored, grooved, or worn at the seal contact area. Instead of regrinding the shaft, this sleeve creates a smooth outer sealing surface that supports reliable crankshaft seal performance. It is a practical service part for rear crankshaft repair on Chevrolet C2500, C3500, K2500, K3500, Express 2500, Express 3500, GMC C2500, C3500, K2500, K3500, and related diesel applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Rear crankshaft seal leakage caused by shaft wear
