Looking for the ultimate engine and transmission package for your next project? Look no further than Speartech for your complete, turn-key powertrain package!

We offer the latest GM crate engines and transmissions including LS3, LT1 (Gen 5), and LT4 (Gen 5). We set our LS3 packages up with the 6L80 transmission. Our LT1 packages can be set up with the 6L80, 8L90, or 10L80. Our LT4 packages are set up with the 8L90 or 10L80 transmission. Whichever combination you prefer, we can do it.

All packages are brand new and include all sensors, front drive accessories, programmed ECM, throttle pedal, front O2 sensors, and fuel filter. All engine packages include our Speartech wiring harness, built entirely on your engine for a precise fit, and we test run each one upon completion to ensure everything works perfectly.

If you prefer to come and pick up your engine package, you can watch it run!

Buy your next powertrain package from a company with years of experience setting these up the right way. We take all the guess work out of "will this work with that, or that work with this" and offer you a complete, turn-key, trouble free, start-up-and-go package!

Please call us at (765) 378-4908 to place an engine package order. We ship worldwide!
