650 Performance Long drive spindles – The long drive is as it sounds, longer than the shorty and designed to ultimately seat into a 3rd bearing support. This comes with everything you need for immediate and simple installation. The stock sport size is 625. Use the 650 for faster outta-the-hole performance or hilly terrain versus the larger 800 drive. This is a knurled steel spindle not that cheezy stock replacement spindle that quickly wears down. (Long Drives do not fit GEO SPORTS but Shorties do!)
