Tech Tip: Easy Front Mount Installations
This battery is supplied with unique terminal hardware (2 spacers and 2 bolts for cable to terminal connection). This hardware is required for proper installation on certain applications. Other hardware may damage terminals and should not be used. The spacers are required for front mount cable installation only! The top mount position does not require the round spacers, use supplied bolts only. Torque bolts to 6 to 8 ft. lbs.

got here fast , fit just right
Good website, good service, battery starts my 03 Bonneville.
Battery shipped and arrived quickly, nice hardware included, easy installation. My bike fired right up!
It wasn't a drop in replacement. There are 3 prongs on the battery cable connectors that would not fit over the battery terminal. I bent 2 of them back on each connector with Vise Grips. Not a big deal and it fires right up. I can't comment on longevity yet. Happy so far!
This is the third big crank I’ve purchased. All 3 were for different vehicles/equipment. Always have been very pleased with the performance right out of the box and shipping is fast.
Great selection of batteries, and easy to find the exact size to fit my custom application (77 ironhead chopper). Looking forward to receiving my new battery, hoping it cranks right up. I will follow up if any issues..
Have had this battery for about a month, so far its great, it spins the crank up way quicker than the old Parts Unlimited Battery.
