Choosing among RC repair tools & parts is easier when the repair comes first: gearing, fasteners, or crawler tires. A pinion gear cannot replace a driver set, and a tire package is a very different purchase from either. Start with the job, then narrow the choice using the stated pitch, bore, scale, tool sizes, or tire dimensions.
Quick take
The two pinion choices serve drivetrain work, the five-piece hex set serves bench maintenance, and the four-tire package serves crawler upkeep. Listed prices span $4.95 to $25.99, a $21.04 difference. Use that spread to frame the purchase, then let the part type and compatibility details decide rather than package count alone.

Decision matrix
Use this quick routing guide before comparing the individual choices:
- Drivetrain gearing: compare the Mod .8 32P 5mm Steel Pinion Gear with the NHX RC 32P 5mm Bore Hardened Steel Pinion Gears.
- Fastener work: the 5Pack 0.9mm-2.0mm Hex Screw Driver Repair Tool is the relevant choice.
- Crawler tire replacement: the 4PCS 1.9-inch RC Crawler Tires are the dedicated tire package.
- Mixed repair needs: separate the job into gearing, bench tools, and tires; none of these choices should be treated as a substitute for the others.
Product notes
Mod .8 32P 5mm Steel Pinion Gear
The Mod .8 32P 5mm Steel Pinion Gear is the direct drivetrain pick when a repair calls for a 32-pitch, 5mm-bore pinion for an electric RC setup. Each gear includes a screw, and the 1:8-scale applications named include buggy, drift car, monster truck, roller, and short-course truck. That makes the part's purpose easy to identify. The concrete limitation is the 5mm motor-shaft requirement: it is compatible only with that shaft. Choose it for a focused gear replacement when the pitch, bore, scale, and shaft details align; it is not a general bench-tool purchase.
NHX RC 32P 5mm Bore Hardened Steel Pinion Gears
NHX RC 32P 5mm Bore Hardened Steel Pinion Gears give drivetrain shoppers a hardened-steel choice with 13T, 14T, 15T, 16T, and 17T selections. The 5mm bore and 1:8 scale are the key fit cues, while the NHX6039 identifier helps distinguish the part in a parts drawer. The limitation is the tooth-choice window: a repair calling for a count outside 13T through 17T is not covered by the choices named here. Pick it when hardened steel and a defined tooth selection matter; the 1:8 scale and 5mm bore keep the choice focused on the matching RC setup.
5Pack 0.9mm-2.0mm Hex Screw Driver Repair Tool
At the bench, the 5Pack 0.9mm-2.0mm Hex Screw Driver Repair Tool is a clear match for fastener work. It is a five-piece CNC-machined metal screwdriver set for RC cars, boats, drones, helicopters, and other hobby models. The set includes 0.9mm, 1.27mm, 1.3mm, 1.5mm, and 2.0mm hex drivers. Its limitation is scope: the package is a hex screwdriver set, so it addresses screws rather than supplying a pinion gear, tire, or suspension component. Choose it when the immediate job is model assembly or repair and those included sizes match your hardware.
4PCS 1.9-inch RC Crawler Tires
The 4PCS 1.9-inch RC Crawler Tires belong in the crawler-focused lane. The package contains four rubber tires for 1:10 RC use, with Axial SCX10 ii 90046 and Traxxas TRX4 named in the compatibility details. The tires are black and measure 120mm in height, 50mm in width, and 48mm at the inner diameter. Its scope is the tire package itself, so a shopper needing wheel or suspension hardware would be looking for a different part type. Choose it when crawler tire replacement is the job and the listed scale, size, and compatibility cues match the vehicle.
Final recommendation by use case
- For a single 32P pinion purchase: choose the Mod .8 32P 5mm Steel Pinion Gear, especially when the 5mm motor-shaft detail matches.
- For a hardened-steel pinion with a defined tooth range: choose the NHX RC 32P 5mm Bore Hardened Steel Pinion Gears.
- For bench fastener work: choose the 5Pack 0.9mm-2.0mm Hex Screw Driver Repair Tool with its five included hex sizes.
- For 1:10 crawler tire replacement: choose the 4PCS 1.9-inch RC Crawler Tires, the only choice here centered on a four-tire package.
