Installation Instructions
Before beginning installation, ensure the vehicle is turned off and the parking brake is engaged. It is recommended to wear appropriate safety gear, such as gloves and eye protection.
Tools Required:
- Wrench or socket set (appropriate size for 5/16-18 nuts)
- Wire brush (optional, for cleaning)
Step-by-Step Guide:
- Prepare the Battery Area: If replacing an existing hold down, carefully remove the old components. Clean any corrosion or debris from the battery tray and surrounding area using a wire brush if necessary.
- Position the Battery: Ensure the battery is correctly seated in its tray and aligned with the hold down points.
- Insert J-Bolts: Select the appropriate length J-bolts for your application. Insert the hooked end of each J-bolt into the designated slots or holes in the battery tray or vehicle frame. The threaded end should extend upwards, passing through the battery hold down bracket (not included in this kit, typically part of the vehicle or battery tray).
- Add Washers and Nuts: Once the J-bolts are in place and the hold down bracket is positioned over the battery, place a washer onto each J-bolt, followed by a nut.
- Tighten Securely: Hand-tighten the nuts first to ensure proper alignment. Then, use a wrench or socket to gradually tighten the nuts. Alternate tightening between the two J-bolts to apply even pressure across the battery hold down bracket. Do not overtighten, as this can damage the battery case or the J-bolts. The battery should be snug and unable to move.

Maintenance
Regular inspection of your battery hold down kit is recommended to ensure continued security and performance. Periodically check the following:
- Tightness: Verify that the nuts are still securely tightened and the battery is not moving. Retighten if necessary.
- Corrosion: Inspect the J-bolts, washers, and nuts for signs of corrosion. Clean any light corrosion with a wire brush. If components are heavily corroded, replacement may be necessary.
- Damage: Check for any physical damage to the J-bolts or nuts, such as bending or stripping. Replace any damaged components immediately.
