Tamiya 54319 M-Chassis Lightweight Hollow Shaft Set OP-1319 - Compact weight-saving upgrade  [54319]

Lightweight hollow shafts built for M-Chassis tuning

The Tamiya 54319 Lightweight Hollow Shaft Set provides a straightforward upgrade path for M-Chassis racers and track-day hobbyists. These hollow stainless steel shafts replace the standard 5x40mm and 5x21mm parts to cut rotating mass without major chassis work.

Real benefits from lighter shafts

Swapping to hollow shafts trims roughly 6 grams from the drivetrain, which can improve throttle response and cornering feel. For racers chasing small gains or club racers wanting crisper handling, the weight reduction is a simple, effective change.

Fits a range of M-Chassis platforms

This shaft set fits several M-Chassis variants, including the M-03, M-04, M-05, and M-06, making it a flexible option for hobbyists who own multiple kits or want an easy parts upgrade across their fleet.
