If you're diving into the world of LS swaps, you know how crucial it is to get the right components to make everything work seamlessly. The Texas Speed Crank Adapter Sleeve is a game-changer for anyone looking to adapt a variety of torque converters, like the Powerglide or TH400, to fit LS and LT engines. This little piece of engineering magic—model number TSP00346—is designed for those who want to make their retrofits as smooth as possible.
What I love about this adapter is its versatility. It works with a whole range of transmissions, including the 4L80E, TH350, 2004R, 700R4, 4L60, and 4L60E from non-LS engines. So whether you're swapping in an LS engine from a classic ride or upgrading your daily driver, this sleeve has got you covered. Just keep in mind, if you’re working with a 6.0L engine from a 1999 or 2000 model, you won’t need this part, which is a nice little time-saver.
It’s a universal retrofit that fits models from 1997 to 2023, making it a solid choice for just about any project you might be tackling. The installation is straightforward, and once it’s in place, you’ll appreciate how well it bridges the gap between your torque converter and the LS flexplate. No more worrying about compatibility issues or awkward fits—this sleeve helps keep everything aligned and running smoothly.
In short, if you’re serious about your build and want to ensure top-notch performance without the hassle, the Texas Speed Crank Adapter Sleeve is definitely worth considering. It’s practical, reliable, and just what you need to get that LS engine purring like a kitten.
