About This Product
S&S drive and idler gear shims for circuit breaker setups. They are .050-inch thick. These shims fit 1936 to 1969 Big Twin models. Use them to set end-play and gear tolerance in the timing assembly. A few thousandths matter. They keep the drive and idler gears spaced right and stop premature wear. Fit them during a timing chest refresh or engine build.
Manufacturer part number: 33-4221.
