  • **Power Bore Sleeves are not available below 4.07" bore size** Texas Speed & Performance is proud to offer our Gen 5 LT1/4 resleeved aluminum GM engine block using state-of-the-art, American made dry sleeves! We are machining and installing Power Bore and Darton sleeves at our facility using new GM Gen 5 6.2L LT1/4 aluminum blocks using only the best CNC equipment available. Both sleeve brands have steps in them to alleviate the possibility of ever "dropping" a sleeve, which could be a problem with straight sleeves. We are using two different size sleeves that will allow for bore sizes from 4.00" all the way up to 4.185"! Both Power Bore and Darton sleeves offer a much higher tensile strength than standard GM sleeves, and you also get a much thicker sleeve that will not distort as much under extreme conditions such as boost or nitrous use. Both brands are 100% made in the USA for the best quality possible! Blocks have incredibly thin sleeves from GM, so the resleeved block is a great option for those needing thicker sleeves for more extreme builds. Resleeving the block before there is an issue is a great option that can save you money in the long run from a catastrophic failure.
