Application Details

SKF designs seals with application-specific materials and construction to match the operating environment. The 15655 transfer case output shaft seal is intended for transfer case sealing service where maintaining lubricant inside the case is critical. This part cross-references Continental 49372 for the same application.

Compatible With 1969-1974 Chevrolet Blazer, N/A and Rear; 1967-1974 Chevrolet K10 Suburban, N/A and Rear; and 1970-1974 GMC Jimmy, N/A and Rear. These fitments include Spicer 20 transfer case applications, including Chevrolet Blazer and GMC Jimmy configurations noted without a 3-speed Saginaw transmission.

What This Seal Helps Address

• Transfer case fluid seepage at the output shaft
• Contamination entering the transfer case through a worn seal
• Lubricant loss that can lead to noisy or rough operation
• Seal wear from age, heat, and road exposure
• Service needs on classic 4x4 driveline components

Installation Notes

Verify shaft diameter, housing bore, and transfer case type before installation. Inspect the output shaft surface for grooves, pitting, or wear that could affect sealing performance. Clean the sealing area thoroughly and confirm the seal is seated squarely during installation. For best results, match the application to the listed Spicer 20 fitment details for Chevrolet Blazer, Chevrolet K10 Suburban, and GMC Jimmy models.
