This 5 speed close ratio gear kit from Quaife features straight cut gears with dog engagement and is designed to fit the original 5 speed F13 or F15 gear casing used in various Vauxhall models such as Astra, Corsa, Nova & Tigra. This comprehensive kit comes complete with a replacement heavy duty end cover, selectors and a crown wheel and pinion with a choice of final drive ratios. The dog engagement used in this gear kit provides rapid gear changes and we recommend using in conjunction with the Quaife Gear lever and turret assembly to get the most precise gear changes.  *Note - Input shaft has 7/8" x 20 tooth spline   table.tableizer-table { border: 1px solid #CCC; font-family: Arial, Helvetica, sans-serif font-size: 12px;} .tableizer-table td { padding: 4px; margin: 3px; border: 1px solid #ccc;}.tableizer-table th { background-color: #104E8B; color: #FFF; font-weight: bold;} Ratios     1st2nd3rd4th5th 2.5401.7601.4201.1901.040
