When you lower a car the pinion angle changes, which can introduce vibrations in the drive shaft and or put the pinion angle out of it's optimal range depending on how much the car is lowered. You can also adjust pinion angle depending on the type of tire you are using at the track\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQuestion:\u003c\/strong\u003e What does double adjustable mean?\u003cbr\u003e\u003cstrong\u003eAnswer:\u003c\/strong\u003e Single adjustable arms have to be unbolted front one end in order to adjusted. Double adjustable means you can adjust the length while the arm is bolted into place.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQuestion:\u003c\/strong\u003e Why are your lower only single adjustable and not double like the uppers?\u003cbr\u003e\u003cstrong\u003eAnswer:\u003c\/strong\u003e Adjustable lowers are used to set the location of the rear end inside the wheel well. This is something that is normally done once and locked into place. Uppers are used to set pinion angle and that is something that needs to be adjustable on the car while dialing in your suspension or when changing to different types of tires.\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"UPR Products","offers":[{"title":"Pro-Series Adjustable Uppers\/Lowers fits 1979-1998","offer_id":54206885822827,"sku":"2001-100","price":626.99,"currency_code":"CAD","in_stock":true},{"title":"Pro-Series Adjustable Uppers\/Lowers fits 1999-2004","offer_id":54206885855595,"sku":"2001-100-99","price":626.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/9690\/4998\/files\/yhst-37354654005614_2271_233931380__21304.1511302091.1280.1280.jpg?v=1792771752","url":"https:\/\/www.raptorracing.ca\/products\/79-04-mustang-pro-series-adjustable-control-arms-package","provider":"Raptor Racing","version":"1.0","type":"link"}
