TRF420 TA-08 TA-07 Gear Diff Shim Set

The TRF420/419X/TA-07 Gear Diff Shim Set is a focused tuning set for oil-filled gear differentials in compatible TA07 PRO, TRF419 and TRF419X chassis. These large-diameter shims are inserted into the differential internals, where they adjust the position of the spider gear assembly and support a more exact internal setup during maintenance or rebuild work. The set provides 3 dedicated shim sizes for differential tuning: 5 x 15 x 0.3 mm shims, 5 x 15 x 1 mm shims, and 2.6 x 9.5 x 0.1 mm shims. That size spread allows fine changes to spacing rather than a single broad adjustment, which is useful when dialing in gear engagement inside an oil-filled unit. The larger outer diameter suits the intended differential application, and the mixed thicknesses give a practical range for setup work across compatible chassis. On the bench, this shim set supports routine differential service, rebuilds, and setup corrections when gear mesh needs closer adjustment. It also suits racers and builders keeping spare tuning parts ready for drivetrain maintenance, especially when reducing skipping is part of protecting the internal gears from avoidable damage.
