:Ok so.... if i decide to buy a new 3rd mem for a 8" rear all i need to do is get the gears in it i want (373 to 391) and buy it with a street locker installed and for 28 spline. Now if i want to upgrade to 31 spline then i need to order it that way and get the new axles in 31 spline? as i assume the 31 spine will not fit in the 28 spline shaft rear? I am also assuming that if i get the gears in the new 3rd mem that its a drop and install job? thanks : : :David, you need some clearing up on the 3rd member info. :Presently at JEG'S and SUMMIT there offering in ratios are 3.55, 3.80 4.11 and 4.62. There are other ratios in between but would have to go to Perogie or another source. ..There are two or three after market traction loks and two factory units. Either way its difficult to lach onto a worth while set up inexpensivly. The after market 8" traction loks are in the range of $400 and gears around $180 plus setup hardware and gaskets, all 28 spline. The 8" uses the same spider gears assembly and clutch discs as the 9" so 31 spline could be fitted to an 8" unit by using 31 spline spider gears BUT the 31 spline 9" axles have to be custom worked for length and possibly bearing size to do this. CURRIE ENTERPRISE can help you with what ever you want. ..If your going to make a lot of power and drag launch at 4000, big slicks and all that, then go whole 9" setup. If not 8" is fine. Either way its going to cost to get what you want unless a tooth ferry visits. Ken |
