These urethane performance bushings replace the stock rubber lower control arm bushings on the Mercedes W202 C-class, W208 CLK, and R170 SLK models. Stock rubber control arm bushings give a disconnected and mushy feel to the front suspension, especially when worn as the bushing deflects more than it should. You get sloppy steering, vibrations, and poor handling which makes the car feel unstable. These urethane bushings are stiffer than stock rubber and will not deflect as much. This helps keep the alignment in check with less variation. The car feels more planted and confidence-inspiring. And a limited lifetime warranty means you’ll likely never have to pay for another bushing ever again (applies to Street bushings only, see warranty page for complete info).Sold as a pair for the back bushings on the lower control arms (see diagram). Replaces Mercedes part #1703300107A.These work best when used with the Powerflex bushings in the front of the control arm (PFF40-601). Powerflex has carefully engineered the bushing materials to work together on this Mercedes front control arm to give you the right amount of precision withoutundue harshness or vibration.OEM Part Number: A2023305107 / A2023305207OEM Part Number: A1703300107 / A1703300207OEM Part Number: A2083300075 / A2083300175Installed in lower control arm:
