Deluxe Seal Kit, NP246 Transfer Case | 1999-2007

Deluxe Seal Kit, NP246 Transfer Case | 1999-2007

The Merchant Automotive Deluxe Seal Kit includes every seal needed to overhaul the NP246 transfer case used in 1999-2007 GM 1500 trucks and SUVs. It covers the front input, front output and rear output seals, the speed sensor seals, the pickup tube seal, the O-rings and the transmission adapter gasket. Instead of ordering each seal separately, you get everything in one kit.

Key Features

• Complete seal kit for the NP246 transfer case
• Front input (A9), front output (A7) and rear output (A13) seals
• Speed sensor seals (A23) and 38-spline pickup tube seal (B30)
• Clutch lever pivot pin and detent plug O-rings
• Transfer case to transmission adapter gasket and snap ring hole grommet

Benefits

A leaking seal lets transfer case fluid drain out, and the NP246 depends on fluid level to keep the pump and chain lubricated. Once the case is apart, replacing every seal at once means no single old seal is left to leak and send the truck back in. Replace if worn or damaged. Commonly used with: Merchant Automotive Transfer Case Rear Output Seal Driver | 2001 - 2019.
