Do all 700R4's have the same gear ratios, or do they come in different ratios?

These will have a 2.84 to 1 first gear, 1.56 to 1 second gear, 1 to 1 third gear and .70 to 1 overdrive ratio. This close ratio 700R4 gear set will have a 10.5% less RPM drop between 1st and 2nd than the wide (stock) ratio gear set. In other words the close ratio gear set will only have 89.5% as much RPM drop as the wide ratio gear set. This is what people have been asking for, for years.
http://www.transmissioncenter.org/700_raptor_700r4_700r4_transmiss.htmThis gear set is used to reduce torque multiplication / rotating speed in the transmission in first gear. This improves track applications that overpower the rear tires upon launch. This is common with numerically high final drive ratios. Now you will have a choice between the wide ratio or the new close ratio gear sets. In first gear this close ratio gear set has a 7.2% numerically lower final drive ratio. It has been reported that the 2.84 gear set could lower your quarter mile time as much as 4/10 of a second over the 3.06 gear set.
