Fill Plug: No Fill Port

A crystal-clear view into one of Chrysler's longest-running rear axle platforms.

Formed from rugged .187" thick polycarbonate and finished with a high-temperature oleophobic ceramic coating that helps repel oil for easier cleaning and lasting clarity. This cover delivers exceptional strength while putting the entire ring gear, differential, and gear oil on display. Whether you're inspecting your rear end, building a show truck, or just appreciate seeing the mechanical side of your drivetrain, nothing compares to a clear differential cover. Watch your gears in motion, inspect oil condition at a glance, and put your Chrysler/ZF 9.25" rear axle on full display.

Made in the USA – thermoformed in-house by Legacy Form USA.

Fits Chrysler and ZF 9.25" rear axles using the 12-bolt differential cover pattern.

Important: Not every vehicle listed above was equipped with a 9.25" rear axle. Multiple axle options were available depending on year, model, engine, drivetrain and configuration.

Before ordering, verify that your vehicle has a Chrysler/ZF 9.25" rear axle and compare your existing differential cover shape and 12-bolt pattern.

This cover is for the Chrysler/ZF 9.25" rear axle. It does not fit the AAM 9.25" front axle used in some Dodge/Ram trucks.

Care Guide

DO:

  • Use the included microfiber cloth

  • Clean with water and mild dish soap

  • Blow off dust with clean compressed air before wiping (if available)

DO NOT:

  • Use harsh solvents (acetone, brake cleaner, etc.)

  • Use ammonia-based glass cleaners

  • Pressure wash from close range or expose to hot degreasers

  • Scrub with paper towels or abrasive materials

The UV and oil-resistant ceramic coating is exceptionally durable but should still be cared for properly.

12-Month Warranty

Covers manufacturing defects for one full year from purchase date.

Heat control is important. Our clear differential covers are designed to withstand temperatures exceeding 300°F, but exhaust components should remain at least 6 inches away or be properly heat shielded to prevent excessive radiant heat from damaging the polycarbonate.

Not recommended for heavy towing.

Legacy Form USA is not responsible for damage caused by external radiant heat sources.

Made-to-order in small batches.

Please verify compatibility before ordering. See our Returns Policy page for details.

Typically ships within 7–10 days.

Ghost Cover FAQ

A: We currently offer Ghost Covers for Duramax, LS, and SBC engine platforms. As well as AAM 11.5/11.8 differentials. Cummins and other applications are in development.

A: Yes — they’re thermoformed from optical-grade, heat-resistant polycarbonate. Each one is coated with a ceramic barrier for added oil repellency and durability.

A: No noticeable yellowing has occurred in testing. Covers are made from UV-stabilized polycarbonate and ceramic-coated for additional protection. Long-term exposure testing is ongoing, but results so far are excellent.

A: They’re made to run. Durability has been tested under heat, vibration, oil exposure, and real-world driving conditions. They’re not indestructible, but they’re absolutely built for real engines, not just display.

A: Installation is straightforward — apply the provided clear RTV sealant, allow it to partially cure (per instructions), then lightly snug the included hardware. We provide 29 bolts for a 28-bolt install… just in case the engine bay eats one.

A: Each cover is handcrafted, and minor imperfections may occur — particularly in areas like the flange or edge. These do not affect performance or clarity when installed. We inspect every cover and only ship what we believe you’ll be proud to run. Expect show-stopping engine bay visibility, not lab-grade perfection under LED magnifiers.

A: Crazing is a fine, hairline cracking that can appear in the polycarbonate during or shortly after ceramic coating. It typically shows up in high-stress flange areas caused by the thermoforming process.
It doesn’t affect strength or clarity in the visible zone and is mostly cosmetic. We actively work to minimize it, but it’s considered a normal characteristic of coated thermoformed polycarbonate.

A: We don’t currently offer a DIY ceramic kit, and flame polishing is not recommended post-forming. All covers ship pre-coated and flame-finished at the factory. Reach out if you’re chasing something custom — we’re happy to talk shop.

A: No — stick to mild soap and water only. Solvent-based cleaners like isopropyl alcohol, Windex, or ammonia can degrade the ceramic coating over time or cause hazing. Use a soft microfiber towel and wipe gently.
