The shift from 3.06 ratio, 1st gear, to 1.63 ratio, 2nd gear, is a dramatic RPM drop that causes performance engines to fall out of their power band. The Sonnax 2.84 input carrier kit transforms the popular 4L60 series from an OE "wide ratio" 3.06/1.63 to a "close ratio" 2.84/1.55 for game changing acceleration on the track. This keeps performance engines in the optimal power band while allowing a longer pull in first and second gears, improving consistency and performance.Manufactured and engineered for outstanding durability, the carrier's gears are precision ground to OE standards, thrust washers feature highly wear resistant PTFE coated material and the captured bearing is thicker late design. Lube channels direct oil to the pinion pins, and the carrier can be disassembled for inspection and service.Keeps engine in power band on 1-2 and 2-3 shiftsDelivers longer pull in 1st and 2nd gearsSix pinion planet loaded with advanced durability featuresNo special tools or machining requiredFits 2006 and earlier reaction shafts onlyRequires OE bearing, 8642191 or 24217327, NOT included in this kit FREE SHIPPING on US Orders GOT QUESTIONS on your specific Year/Make/Model?
