Differentials & Components

What This Collection Covers

This collection combines fifteen related differential and drivetrain categories, including diff braces, diff covers and gaskets, rebuild and overhaul kits, install kits, seal kits, bushings, mounts, housings, dropouts, spider gears, yokes, complete differentials, and final drive gears.

Product Types in This Collection

Shoppers will find billet differential braces for high-horsepower RWD platforms, nodular iron and aluminum diff covers, master overhaul kits, differential-to-cradle bushing kits, and limited-slip differentials.

Differential Braces for High-Horsepower Platforms

Differential braces reinforce the differential housing and cradle mounting points to reduce flex and axle movement under high torque loads. This collection includes braces specifically built for the Jeep Grand Cherokee Trackhawk, Dodge Durango Hellcat, and Dodge Charger, Challenger, and Chrysler 300 V8 and Hellcat models.

Diff Covers, Rebuild Kits, and Install Kits

Diff covers add capacity and protection to the differential housing, while rebuild, overhaul, and install kits supply the bearings, seals, and shims needed to service or rebuild a differential. This collection includes coverage for Dana 60 and 61, Chrysler 8.25 and 9.25 inch, GM 8.2 and 8.5 inch, and Ford 10.25 and 10.5 inch housings.

Matching the Correct Housing

Diff covers, gaskets, and rebuild kits are housing-specific rather than vehicle-specific in many cases, so confirm the exact differential housing and ring gear size before ordering.

Differential Bushings and Mounts

Differential bushing and mount kits reduce unwanted movement between the differential cradle and body, improving power delivery and reducing wheel hop, with dedicated kits for the Jeep Trackhawk and Dodge Durango and Chrysler 300 platforms.

Limited-Slip Differentials and Locking Differentials

Limited-slip and locking differentials improve traction by controlling power delivery between the left and right wheels, with applications available for Subaru WRX and STI and classic Datsun and Nissan Z platforms.

Vehicle and Housing Coverage

This collection spans Jeep Grand Cherokee Trackhawk, Dodge Durango, Charger, Challenger, and Chrysler 300, RAM 2500 and 3500, Jeep Wrangler, Subaru WRX and STI, and classic Datsun and Nissan Z platforms.

Confirming Fitment

Always confirm the exact year, make, model, and differential housing before ordering, since many parts are specific to a particular axle housing rather than universal across a vehicle line.

How to Choose the Correct Differential Component

• Confirm the exact year, make, model, and differential housing
• Identify the ring gear size and housing type for diff covers and rebuild kits
• Decide whether you need a full differential, a rebuild kit, or supporting hardware
• Confirm front or rear application for braces, bushings, and mounts
• Verify gear ratio compatibility for final drive gears

Common Questions

What does a differential brace do?

A differential brace reinforces the housing and cradle mounting points to reduce flex under high torque, helping maintain consistent pinion angle and reduce drivetrain stress.

Do I need a rebuild kit or an overhaul kit?

Overhaul kits typically include a fuller set of bearings, seals, and shims for a complete rebuild, while rebuild kits may cover a more limited scope. Check the kit contents against your service needs.

What is the difference between a limited-slip and a locking differential?

A limited-slip differential allows some speed difference between wheels while transferring power to the wheel with traction, while a locking differential forces both wheels to spin at the same speed when engaged.

Will a diff cover fit any vehicle with the same axle brand?

Diff covers are matched to the housing and ring gear size rather than the vehicle brand, so confirm the exact housing designation before ordering.

Do differential bushing kits require special tools?

Many differential bushing and mount kits require a press or specialized tools for removal and installation and are often best handled by a professional shop.

Do these products come with a warranty?

Yes. Differential components include the applicable manufacturer warranty. Terms vary by brand and product line.

How long does shipping take?

Most in-stock orders ship the same day. Delivery typically arrives in 2 to 5 business days.

Can I install these parts myself?

Diff covers and gaskets are suited to an experienced DIYer, while rebuild kits, gear sets, and bushing replacement are typically best handled by a professional drivetrain shop.

What is the return policy?

Unused parts in original packaging can be returned within 30 days. Installed parts and gear sets are non-returnable once fitted.

Do I need to change differential fluid after installing a new cover or gears?

Yes. Any differential service that opens the housing requires refilling with the correct gear oil and following the proper break-in procedure for new gears.
