The battery in your Mustang is one of the most important pieces and vital to your Mustang coming alive. This 1986-1993 Mustang 5.0 battery tray and cable kit will restore the components your battery needs to function and stay secure. This 5.0 Resto kit includes a new battery tray with hold down and hardware, positive battery cable, negative battery cable, and starter cable. These components will ensure your battery is powering your Mustang safely and securely.

Battery Tray Kit.
The battery tray in your Mustang mounts to the front fender apron and provides a safe place for the battery to sit while protecting the metal apron from the corrosion caused by the battery. It is extremely common for the plastic battery trays found in Mustangs to be completely rotten after years of abuse. Once your battery tray has reached this level of deterioration your Mustang is generally unsafe to be driven on the open roads and will probably not pass tech inspection at the race track. This kit includes a new tray, mounting hardware, and battery hold down clamp.

Battery Cables.
Just like the battery tray, the battery cables in your Mustang are vital to the operation of your Mustang. This kit includes new positive and negative battery cables. Over time, corrosion will deteriorate your battery cables which causes power loss, battery drain, and makes it unsafe to operate your Mustang. This kit includes new four gauge wires that are the correct length for a quick and easy installation.

The tray was removed and a penetrating catalyst was applied to the bolt.

Once the bolt was out of the way, I removed the speed nut from the frame rail provision; use a magnet to fish it out of the frame rail if it happens to fall inside upon removal.

Go ahead and support the front of the car with jack stands.
