Care Guide:

DO:
Use soft microfiber cloth (included)
Clean with water + mild dish soap
Blow off dust with clean compressed air before wiping (if available)

DO NOT:
Use harsh solvents (e.g. acetone, brake cleaner, or alcohol — polycarbonate doesn’t mind,
but the ceramic coating will)
Use glass cleaners with ammonia
Pressure wash up close or hit with hot degreaser
Scrub with paper towels or abrasives
The UV and oil-resistant coating is tough, but not indestructible

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 upwards of 300° but exhaust pipes should be kept a minimum 6" away or have heat shielding to keep radiant heat from potentially damaging the polycarbonate. Not recommended for heavy towing.

Legacy Form USA is not responsible for damage from outside radiant heat sources.

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.
