Since 1990, an ever increasing number of cars, trucks & SUV's "get screwed" with Kenne Bell Twin Screw Superchargers and experience the unprecedented boost in power and torque. To celebrate our 10th anniversary, we are introducing our new "Get Screwed" T-Shirts. This high quality shirt is close knit 100% cotton with double stitching. Available in Large, XLarge and XXLarge in white with red, blue & black lettering, black with red, white & blue lettering and navy with yellow & red lettering. Offered with the popular "Get Screwed" front - or for our more conservative customers - a smaller version of the shirt back on front.
