NP261 Rebuilt Transfer Case for 4x4 Van Conversions
The NP261 was built by New Process (New Venture) and is a reliable chain-driven transfer case used primarily in Chevrolet and GMC vehicles from 1999-2007. This unit has a left-side drop output and a low gear ratio of 2.72 to 1 with 2 high, 4 high, neutral, and 4 low.
The units we provide have 29 and 32 spline inputs and 32 spline outputs for both front and rear slip yokes. No core charge, 1-2 weeks build time. Timberline 4x4 GM conversions require a bit of clearancing on the T-case. If you provide your vehicle and conversion information by email when ordering, we will pre-trim your case for you free of charge.
-Case inspected, dismantled, solvent-based heated cleaning, smoothed and painted with high-build grey paint.
-Replacement of hard parts showing any signs of wear or potential failure, replacement of chain and any other hard parts needed.
-Replacement of gaskets, seals, and bearings with OE quality parts and Nachi/Koyo bearings

Note: Units are rebuilt with remanufactured cases. Cases may show small pockmarks, imperfections, and chips. We do our best to make cases attractive and more importantly reliable, but cosmetic imperfections may be present.
Why 261 notes: We have built G-series vans with 261, 241 and Magna 1225/1226 transfer cases. Nothing holds up as well as the 261 and runs as quiet when you're basically sitting on top of the transfer case with a hole down through the floor.
