LS3 525hp TKX 5-Speed Manual Connect & Cruise Package



We at Pro Touring Store put the latest Tremec TKX 5-speed manual transmission in place of the T56 6-speed offered by Chevrolet Performance, so you get a more compact transmission for your classic ride!

The TKX transmission features internals similar to the T56 Magnum, so the shifts are smooth, and sustain higher RPM use (as compared to other 5-speeds). 
Additionally, the TKX 5-speed is super compact, fitting into muscle cars such as 67-81 F-Body, 64-72 A-Body, Chevy Nova's and others, without modifying your transmission tunnel. 

What do you get when you take Chevrolet Performance's aggressive ASA camshaft - developed for the high-rpm world of circle-track racing - and slip it into an LS3 6.2L engine? The answer is 525 horsepower in one of our most powerful production-based crate engines. We call it the LS376/525, and if take-no-prisoner performance is what you're looking for in your new Camaro or resto-mod Chevelle, this is it!!
