WARN 9790 Standard Manual Locking Hub with 19 Splines - OEM Fit

In this review the WARN 9790 Standard Manual Locking Hub is evaluated as a direct OEM replacement for older 4x4 trucks that use 19 spline axles. The bottom line: it is for owners who need a reliable, durable pair of internal mount hubs that match factory fit and function without extra frills. The review focuses on fitment, materials and real-world use, and finds the hubs deliver strong value because of their precision cast body, hardened 4140 steel clutch ring and inner gear, and the lifetime limited warranty that backs them.

Key Features

• OEM fit: Designed as a direct OEM hub replacement to simplify installation and maintain original vehicle geometry.
• Durable materials: 4140 steel clutch ring and inner drive gear resist wear under heavy use for long service life.
• Precision casting: The precision cast hub body provides consistent tolerances for reliable engagement and smooth operation.
• Lifetime limited warranty: Coverage from the manufacturer reduces long term ownership risk and confirms build confidence.
• Pair included: Supplied as a set of 2 internal mount hubs so both sides are matched for balanced performance.
• 19 spline compatibility: Specifically made for use with 19 spline axles to avoid fitment guesswork on compatible vehicles.

Who It's For

The WARN 9790 is aimed at owners of classic and late 20th century Chevrolet trucks and SUVs who need a direct replacement for worn or damaged manual locking hubs. It suits DIY mechanics and restoration shops that prioritize correct OEM fit, robust steel internals, and long-term coverage with minimal modification.

Those who should look elsewhere include owners who need a sealed, low-maintenance automatic hub or vehicles with splines other than 19; this model is an internal mount, manual hub intended to replicate factory behavior rather than add new electronic features.

Pros & Cons

Pros

• Solid OEM-level fit that customers report matches well and installs without hassle.
• High-quality 4140 steel components deliver dependable engagement and long wear life.
• Lifetime limited warranty provides peace of mind for extended ownership.
• Sold as a matched pair so both sides share identical performance.

Cons

• Manual internal mount hubs require occasional intervention versus sealed automatic hubs.
• Fitment is limited to 19 spline axles and compatible vehicle models, so incorrect axle spline will prevent use.
