Buying Guide
Key considerations when selecting an NP231 transfer case chain:
- Model compatibility: Confirm NP231, NP233, BW1350, and related variants before purchase. Some chains are narrow (1 inch) while others are wider (1.25 inches).
- Chain length and width: Match 31-link or other specified lengths. Verify width to fit your specific transfer case cover and sprockets.
- Manufacturing quality: Look for chains from brands with explicit quality controls, heat treatment, and tolerances to reduce wear and failure risks.
- Intended vehicle type: Jeep Wranglers, Cherokees, and older Dodge or GM 4x4s often use NP231 or NP233; choose a chain specified for these platforms if applicable.
- Installation and fitment: Some chains require precise timing and alignment with factory sprockets; improper installation can lead to failure.
How to Compare Chains Quickly
- Best for: Choose the option that explicitly lists your transfer case model as compatible.
- Better for: Chains that mention robust manufacturing and QC processes if you plan off-road use.
- Avoid this if: The chain width or length does not match your NP231/NP233 configuration.
