Achieve seamless LS engine integration with the GM LS1/LS6 Torque Converter Adapter Sleeve Kit (TB-1070-BK), a black finish adapter sleeve designed to connect Gen III LS engines to a range of classic automatics. This direct bolt-on kit empowers you to pair LS1/LS6 power with TH350, 700R4, 200-4R, 4L60 and Powerglide transmissions without expensive modifications. Built for durability, it features double welded ring gears and is compatible with the factory LS starter motor for straightforward installation.

Designed for 1997–2007 GM LS1/LS6 engines (up to 2009 for LS2) and for 4.8/5.3/6.0 truck engines including L33, L59, LM4, LM7, LQ4, LQ9, and LR4, this sleeve adapts these engines to transmissions that originally paired with non-LS V8s. It supports both 10.75" and 11.066" (11.1") bolt-pattern torque converters, ensuring proper alignment and secure engagement. A key advantage is its direct bolt-on compatibility for Gen III LS engines with a short crank flange, simplifying installation and reducing the need for extensive fabrication.

Note: Some 1999–2000 LQ4 6.0 LS engines that used a 4L80E may not be compatible due to the tall crank flange. Always verify crank flange and converter compatibility before installation. Color may appear slightly different from photos due to lighting, and slight dimension variations can occur from manual measurements.
