These type of batteries are not rated in cranking amps, But instead amp hours. The hawker is a 16 amp hour battery and the one that we are useing is a 20 amp hour. Also our battery price will be competitive. The battery you are looking at requires you to buy the posts for an addition $11 each also. We will be selling a complete ready to drop in assembly. You can mount them in any car and if you do not want the specialty-Z name will also supply them saying Dupree Racing or plain. We have been testing these out for close to 2 years with great success :)
