Universal Bolt In Battery Box

Universal Mount Battery Box for Harley-Davidson – Fits YTX20 & YTX20L Batteries

If your oil tank doesn’t include a built-in battery box, this universal mount battery box is the clean solution you’ve been looking for. Designed to fit the most common Harley-Davidson style batteries, the YTX20 and YTX20L, this box provides reliable mounting in a compact vertical setup.

Typically mounted under the chassis in front of the rear fender, the box is built from durable mild steel and ships raw so you can finish it in paint, powdercoat, or chrome to match your build. The YTX20 series batteries are popular for their compact size and high cold cranking amps—more than enough to power even big bore and stroked motors.
