Great stuff!
Had a ls swap already utilizing corvette accessories. Wanted to add the LSA. Came across this page, browsed products. Called in and spoke with Greg. Got all the answers I need. Ordered the high mount AC, Race drive, AC compressor and some other small items to complete my install. Everything went great, products are made very well and nice quality. No belt slip, plenty of adjustments to go with different pulley combos. Overall very happy with my experience and with the products and I highly recommend them.

Fit is great easy to install all parts are very good quality helped belt slippage but did not totally eliminate it I believe mostly due to the small upper pulley (2.55)

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!!
