Need a better-performing transmission for your GM truck? Why buy a new transmission when you can rebuild and improve the one you have? Allison 5-speed transmissions were fantastic in their time with smooth shifting and some tough internal components. However, if you use your truck for heavy-duty hauling it can take its toll on any transmission no matter how tough it is. Get your Allison transmission feeling as good as new with SunCoast's Allison Rebuild Kits. Made with advanced friction materials and exact performance specifications you can be sure your transmission is going to feel better than the first day you drove it.  Put some reliability, performance, and longevity back into your truck so you can tow, race, or just drive to work with fantastic peace of mind.
