The Team Losi Racing Gear Differential for the 2WD 22-series of vehicles can provide another tuning aid in your arsenal. This low maintenance gear differential has been designed to drop right into the 22-series transmission cases, so there is no need hand-fit, modify or alter your car to make it fit. Besides providing improved performance on all types of surfaces, the gear diffs can be accurately and consistently tuned using diff fluid. Their cases are machined from 7075-T6 aluminum to balance out weight, durability and performance.
