Product Description

CPP NP271 AND NP273 TRANSFER CASE CHAIN & SPROCKET KIT FOR DODGE, FORD AND GM TRUCKS

Stop chain slap, slack and jumping under load. The CPP NP271 / NP273 transfer case chain & sprocket kit gives your 4x4 a fresh, tight drivetrain by replacing the worn chain and matched sprockets inside the NP271 or NP273 transfer case used in many Dodge/Ram, Ford Super Duty and GM heavy-duty trucks.

Features & Benefits

• Direct-fit NP271 / NP273 solution designed for common Dodge, Ford and GM 4x4 applications that use these transfer cases.
• Restores positive engagement by eliminating stretch and wear that cause chain skip, noise and vibration.
• Matched chain and sprockets help maintain correct pitch and tooth contact for long service life.
• Heavy-duty construction built to handle towing, off-road and tuned power levels better than tired OE components.
• Kit-based approach saves time versus piecing together individual chain and sprocket part numbers.

Cross-Reference / Alternatives

This CPP kit is designed as a replacement for worn OEM NP271 / NP273 chain and sprocket sets. It can be used when rebuilding your transfer case instead of buying individual OE components. If your case housing, bearings or planetary assembly are damaged, pair this kit with a complete master rebuild kit or a remanufactured transfer case.

Installation Notes

• Remove the transfer case and disassemble according to the factory service manual or a trusted rebuild guide.
• Inspect the case halves, bearings, planetary assembly and shift forks for wear or damage before reassembly.
• Pre-lube the new chain and sprockets with clean ATF or transfer case fluid before installation.
• Verify correct placement of snap rings, thrust washers and oil passages during reassembly.
• Refill with the correct transfer case fluid and check for leaks and proper 4x4 engagement after a short test drive.

Frequently Asked Questions

WILL THIS KIT FIT MY TRUCK?

This kit is designed for transfer cases that are clearly labeled NP271 or NP273 on the factory ID tag. These units are commonly found in Dodge/Ram 2500 & 3500, Ford F-250 & F-350 Super Duty, and some GM 2500HD & 3500HD 4x4 trucks. Always confirm the model number on your transfer case tag before ordering.

WHAT DOES THE CPP NP271 / NP273 CHAIN & SPROCKET KIT INCLUDE?

The kit includes a heavy-duty replacement chain and matched sprockets for the NP271 / NP273 transfer case, plus any small hardware pieces specific to this configuration. Refer to the product images and notes for the exact contents of the kit you are purchasing.

WHEN SHOULD I REPLACE THE TRANSFER CASE CHAIN AND SPROCKETS?

Common signs include rattling or grinding noises in 4x4, a feeling of slip or surge under load, metal shavings in the transfer case fluid, or visible stretch and wear on the original chain and sprockets during teardown. If you are already rebuilding the case, replacing the chain and sprockets is cheap insurance.

CAN I INSTALL THIS KIT AT HOME?

A skilled DIY mechanic with proper tools, a clean work area and a service manual can rebuild an NP271 or NP273 at home. If you are not comfortable with drivetrain teardown and reassembly, a professional driveline or transmission shop can handle the install.

DO I NEED ANYTHING ELSE TO COMPLETE THE JOB?

Most rebuilds will also require a transfer case master rebuild kit with bearings, seals and gaskets, along with fresh fluid. Inspect your yokes, u-joints and driveshafts while everything is apart and replace worn components as needed.
