m&mv80 Posted April 13, 2009 Share Posted April 13, 2009 as the title says really, i have the chance to get a couple of 4.7series diffs and its got me thinking, im running a v8 in my 90 with 35 inch tyres and it could really do with the ratios changing as it struggles a bit pulling away and cant hold 5th on any sort of a hill, having seen the price of 4.1 ashcrofts i was wondering if you can strengthen series diffs as a cheaper alternative, maybe pegging them would help? i have heard people say they are not as strong but by how much? so can i just use the diffs as they are? will pegging help? swap the crown wheel and pinion into my origional housings? (i believe you need a spacer to do this) will my detroit locker fit if i change the ratios? keep saving until ican afford the ashcrofts parts? its only for playing not for competition, im quite sympathetic to the drive train and ive not broken a std 3.54 as yet (touch wood) thanks in advance martin Quote Link to comment Share on other sites More sharing options...
