Collection: Speartech Canada - Authorized Dealer - My Parts Guy

Speartech specialises in wiring harnesses and control hardware for GM LS and LT engine swaps. Its stand-alone harnesses are built and labelled for a specific engine and transmission combination, so an LS3 or LT4 can run in a chassis it never came in without splicing into the donor body harness. The catalogue also includes neutral safety modules, transmission control modules, drive-by-wire pedal kits, gauges and the sensors a swapped powertrain needs to run closed-loop. Harnesses come tuned and terminated, which removes most of the guesswork from a crate powertrain install. My Parts Guy ships Speartech across Canada with CAD pricing.
