The Runnin4Tacos (R4T) Billet Aluminum Battery Tie-Down Bracket: Affordable Mod & Solution For Securing Larger Upgraded Group 31 Batteries
When it comes to electronics, the battery is often one of the last items to be upgraded. For those who are ready to perform that upgrade, it seems the only option is to upgrade the space it resides in. While many companies offer complete boxes for the popular Group 31 battery, they come with a formidable price tag and encase it in quite a bit of metal.
That complete cage is great for those who push their rigs to the limit. However, it’s a bit excessive for the daily driver, weekend warrior, or moderate overlander. The R4T billet aluminum battery tie-down is a simple and budget-friendly solution.

R4T Billet Aluminum Battery Tie-Down
Overview
The R4T battery tie-down is a solid piece of 6061 clear anodized aluminum that accommodates larger, flat-top AGM batteries. The embossed R4T logo is surrounded by a topographic design that complements the outdoor spirit most of us have.
The strong and lightweight billet aluminum easily keeps your battery secured on rough trails. It provides the closest guarantee of keeping it secured in its factory cradle without resorting to full enclosures.
This product will also work for other Toyota models (4Runner, GX, FJ Cruiser). Confirm your fitment before buying.
Why You Should Upgrade
While it may seem odd to upgrade just the tie-down, it’s a critical component in your overall power upgrade. The factory part is designed to only fit a group 24F battery, so upgrading to a Group 31 necessitates an upgrade.
The cheap metal most of these are made of will begin to flex over time when frequenting tougher trails. Rust and corrosion will also accelerate wear, making their reliability questionable. That’s not a concern with the R4T billet aluminum battery tie-down.
What’s Included
Included in the box are the block itself and two j-hooks, one shorter than the other. All hardware needed for installation is also provided.
There are no instructions included, but the installation is simple enough and outlined in this post.
Installation
Tools Required
- 10mm crescent wrench
- 11mm crescent or socket wrench
Installation of the billet tie-down is a simple process. You don’t even need to remove the battery from its cradle. Ideally, having electrically insulated tools is preferred as we’ll be disconnecting and working it.
Step 1. Disconnect Battery
The very first step is to disconnect the battery. Though we are not moving it, this is highly recommended as we are working around a live connection. Starting with the ground (black) terminal first, loosen the screws with a 10mm wrench. Next, disconnect the positive (red) terminal. Be sure the negative and positive cables don’t touch each other. Finally, move the cables to a safe place that’s out of the way.
Once the terminals are out of the way, unscrew the sole fastener from its J-hook with a 10mm wrench. When the fastener is fully removed, lift the factory tie-down away from its J-hook and remove both ends. This takes care of the smaller, attached hook on the tie-down.
Step 2. Assemble & Install Tie Down
With the old tie-down removed, attach the smaller J-hook to the rear-facing portion of the R4T tie-down. You can choose which side you want to face up, this won’t affect installation.
Next, fasten the j-hook with included fasteners, leaving around two threads exposed on top. This step is optional as you can place the hook into the hole by the battery without the main aluminum section but it does make the installation easier.
Insert the smaller J-hook into the rear hole behind the battery. There will be an eyelet that will be fairly difficult to see based on your lighting situation.
Once the smaller J-hook is secured, insert the larger J-hook into the front hole below the cradle. Attach the fastener to the larger J-hook and tighten both ends with an 11mm crescent wrench until the billet tie-down is firmly secured to the battery.
Finally, reconnect the terminals starting with the positive cable first and verify power is back in the truck.
Final Thoughts
Although the R4T billet aluminum tie-down is made to support a Group 31 battery, it will still accommodate smaller AGM batteries. R4T emphasizes that only AGM can be used for this tie-down and it’s best to heed that warning. They also say that it won’t work with Toyota factory batteries as the cells are raised and would not allow the tie-down to perform as designed.
As long as your aftermarket choice is AGM and a flat top, it will work. For example, I currently have a flat top Duralast 24F in my truck and this mod works perfectly. If you’re planning to upgrade your truck’s battery and don’t want to commit to an entire aftermarket enclosure, the R4T battery tie-down is a budget-friendly solution that I would easily recommend.
