Kam Ring and Pinions

Since fitting the Simex tyres I have found the gearing to be too high This means that I am going though clutches in about 2000 miles. It also made it fun to drive off road as the 1 st gear in low was still a bit too high. I needed to change my gearing to cope with this. So I changed from the 90 (3.5) gearing to the Series (4.7) gear ratios for the Diffs. This is because the extra gear the simex have given me is 28% , work on the fact that the original tyres supplied with the 90 from the factory were 205's. If you fit 4.7 ring and pinions it will take me down by 30%, so almost about right to the factory settings But the only problem is that the ring and pinions for a series diff are as strong as toffee. The only way around this is to get the Kam ring and pinions, which are stronger. They are mainly used for the racing boys in comp safari. As you can see from the pictures they are allot stronger and thicker than the original 3.5 These placed in the Diff along with the ARB and Maxi Drive shafts, should in my mine give me the strongest Land Rover axle I can get

3.5,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 4.75

 

The one on the left is the 4.75 as you can see it is quite a bit thicker

This is them made up into the Diff. On the right is a standard 90 3.5 diff . and on the left is a diff with An ARB locker and the Kam 4.75 ring and pinion. As you can see there is quite a bit of difference, and yeah they are heavier :-)
