Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.

About this product
Precision pinion replacement for MAXX diffs
This 4-piece pinion gear set is intended as a direct replacement for TRAXXAS MAXX MONSTER TRUCK differential pinions. The TXMS1201S/G2 gears are produced to hardened steel #45 material standards to improve resistance to wear compared with typical softer pinions, providing a firmer and more repeatable mesh under load.
When installed in the front, centre, or rear differential carriers these pinions reduce clearance between mating gears, which can help stabilise the mesh and improve differential reaction. Confirm bearing tolerances and set mesh precisely to avoid excess preload or premature wear.
Packing includes
- Pinion Gear – 4pcs
Original Name / Part No:
8982
Specifications
- Item Differential pinion gear set
- Material Hardened steel #45
- Model Number TXMS1201S/G2
- Compatibility TRAXXAS MAXX MONSTER TRUCK
- Quantity 4 pcs
- Part Type Front/Center/Rear differential pinion gear
Recommended for hobbyists seeking a precision hardened replacement to reduce backlash; set mesh and check bearings during fitment for best results.
This item is compatible with
- TRAXXAS-1/10 MAXX MONSTER TRUCK-89076-4
- MAXX W/WIDEMAXX MONSTER TRUCK-89086-4
What tolerances should I check after fitting?
Verify axial play on the pinion shafts and radial bearing clearance, then set gear mesh so teeth contact evenly without binding.
Is any break-in required for hardened steel pinions?
A short running-in period under light load can help mating surfaces settle; inspect mesh after the first few runs and retighten diff hardware if necessary.
Can these pinions be paired with aftermarket gears?
They are designed to match TRAXXAS MAXX differential geometry; if using non-standard crown or spider gears, verify tooth profile compatibility and mesh before final assembly.
What maintenance extends life of these pinions?
Maintain clean gear oil or grease in the diff, check bearing condition regularly, and avoid sustained overheating or debris ingress. Write Product Review Please sign in your account before you can write any review.
