Control Arms w\/ rod end \u0026amp; bushing 79-04 - 555-4101\u003cbr\u003e\n\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eWhenever you lower a Fox body or SN95 Mustang you are going to change your pinion angle in the rear suspension. Not only does this affect the driveline angle, but it can lead to driveshaft vibration, and a loss of rear grip \u0026amp; traction. The easiest way to remedy this is Steeda's double adjustable control arms. Serious drag racers, adjust driveshaft-to-differential pinion angle for maximum traction and solid launches. Steeda's double adjustable design lets you adjust the arm length without removing them from the car. Heavy duty steel construction virtually eliminates suspension deflection. The street\/strip arms use Steeda's exclusive 3-piece bushings with a hard center section to give excellent control, and softer outer bushings to prevent binding. Competition arms feature race-quality spherical rod-ends for minimum deflection. Our arms are also available with the bushings for the differential; something the \"other guys\" don't include with their upper arms.\u003c\/p\u003e\n\u003cp\u003eThis kit includes Diff Bushing kit \u003cstrong\u003e555 4100 BK\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Does not fit 1999-2004 Cobra\u003c\/p\u003e\n\u003csection\u003e\u003cstrong\u003eProduct Benefits\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eBetter handling, more stable cornering\u003c\/li\u003e\n\u003cli\u003eEliminates side to side \"sloppiness\" in the rear end\u003c\/li\u003e\n\u003cli\u003eWide adjustment range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/section\u003e\n\u003cp\u003e\u003cbr\u003e\n\u003cbr\u003e\u003c\/p\u003e","brand":"Steeda","offers":[{"title":"Default Title","offer_id":48145520656642,"sku":"SDA-555-4101","price":274.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/0618\/0354\/files\/555-4101_1.jpg?v=1785004185","url":"https:\/\/www.lethalperformance.com\/products\/steeda-double-adjustable-upper-rear-control-arms-spherical-diff-bushing-1979-2004-mustangs-555-4101","provider":"Lethal Performance","version":"1.0","type":"link"}
