This is causing higher side loads for McPherson strut type suspensions. The 25 mm shaft upgrade provides a stronger strut construction with less flex when loaded. This decreases friction and extends its life span- Increased response time\u003cbr\u003eDue to the larger diameter shaft, the volume of oil displacement increases resulting in betterdamper response with small suspension movements. When using stiff springrates, which is the case on race cars, the amplitude of the damper is small with a high frequency. It isimportant the damper controls the movement of the suspension under these circumstances\u003c\/p\u003e\n\u003cp\u003e- Lifting force\u003cbr\u003eThere is a correlation between the shaft diameter and the nitrogen gas pressure resulting\u003cbr\u003ein a lifting force the damper creates. The lifting force pushes the tire on the road surface\u003cbr\u003ecausing the wheel to return quickly after hitting a bump. With the 25 mm shaft upgrade\u003cbr\u003ethis force is increased, resulting in a better handling car with more grip\u003c\/p\u003e","brand":"JRZ Suspension Optional","offers":[{"title":"Default Title","offer_id":45103817425155,"sku":"99-56-51-47","price":340.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.elite-performance.com\/products\/option-set-551675-select-2","provider":"Elite Performance","version":"1.0","type":"link"}
