Strong cranking power for large displacement engines Rated by PurSid on June 08, 2020
Summary: Excellent batter if you need more power. After putting in a 120ci Harley Crate engine the stock battery couldn't keep up with the higher compression. Replaced stock with this direct fit replacement and the engine fires up a lot faster.Well worth the additional cost over a stock battery.
Yes, I recommend this product.
