Diff Sanding Tool (msrp $ 8.50)
Can be used for regular or D-style large diff rings or stealth diff rings - use this tool to sand your diff rings. IRS founder Dave Irrgang was instrumental in developing this technique for making your diff rings grip your diff balls better and making your diff smoother. R/C cars use a friction diff design and using the IRS Diff Sanding Tool has saved many a finger print from getting sanded off.
For 1/8" diff balls we recommend 400 grit paper, for 3/32" diff balls we recommend 800 grit paper.
