Ohlins STX Classic Rear Shocks For Harley Sportster If you've spent any time around a race track, you know the name Ohlins. As the entry level offering in the Ohlins line, the S36E provides a hugely improved ride over stock without all of the bells and whistles that drive cost up. The S36E rear shocks utilize a 36mm piston immersed in oil and controlled by a specially tuned shim stack backed up with a nitrogen charge. Good solid suspension with no frills. While you won't get the rebound and compression adjustments found on higher end shocks, the S36E offers the feel and performance of a premium shock without breaking the bank. If you are a set-it and forget-it type of rider who doesn't want to mess around with knobs and dials the S36E should be on your wish list! Features: Nitrogen charged emulsion shock absorber STX single tube design Built-in adjustable preload Precision CNC-machined components Low-friction piston rod and eyelets Serviceable and repairable 36mm piston diameter Includes preload adjuster tool Sold as a pair
