Package Includes:

(1) HD Main Shaft (49 Spline Pump & 32 Spline Output)

- This Heavy Duty transfer case shaft fits New Process and New Venture 261 & 263 units that came behind 4L80e transmissions. You'll find HD transfer cases in Chevy and GMC trucks that came with gas engines. This main shaft has an output with 32 splines. Please count your output yoke splines to verify proper fitment.

- Our mainshaft comes precisely ground for stability and proper bearing tolerances. It includes an updated snap ring to replace your old stock ring. If your transfer case was run out of oil and a bearing seized on your stock main shaft, it is crucial you replace it with this upgrade.

- Rigid Axle is proud to offer our customers a full line of differential, transfer case, and transmission parts. We specialize in complete rebuild kits for domestic cars and trucks. Give us a call with your year, make, and model and we'll build you a custom kit for your build!
