Boonville, Ind. - AFCO Racing Products is proud to announce the launch of our new 75-78 Series 1/2" Shaft Steel Mono-tube Bulb Shocks. Targeted at the open wheel modified racing market, this shock program promotes better feel and improved grip. The smaller 1/2" (12.7 mm) shaft displaces less oil when compressed, giving the shock an added advantage of less rod pressure gain, thus improving driver feel.
