HD Race Drive - V1 LSA Project

Where to start!.. incredible product, incredible engineering & design.. and world class customer support! Greg helped guide me through the blower drive configuration on my build and recommended the HD Race Drive... and after the solid performance there is zero chance I’d recommend anything else for the LSA set-ups out there! I recommend it to EVERY person I know that is considering the LSA upgrade.. and to those running OE LSA applications. I could rave all day about LSX Concepts.. but I’ll just go ahead and recommend you experience the quality of the product first hand!!

Works very well

Used it on our LSA powered 1981 Trans Am and it works great. Excellent belt wrap and enough flexibility to run various pulley sizes.
