Shopping for RC repair tools & parts gets tricky when one choice is a small drivetrain fix and the other is a complete crawler-tire replacement. The deciding question is not which item seems more useful; it is whether your repair starts at the drive shaft or the wheels.
XRAY 305241 is a focused replacement-cap package, while the 4PCS RC Crawler Tires set addresses a tire change. Here is how the two differ in price, application, and fit.
Quick verdict
- Choose XRAY 305241 for compatible XRAY RC vehicles using composite drive shafts and needing the named replacement caps.
- Choose the 4PCS RC Crawler Tires for a crawler tire job involving 1.9-inch wheels, with compatibility named for Axial SCX10 ii 90046 and Traxxas TRX4.

Where each product wins
XRAY 305241 wins for a targeted drivetrain repair
The XRAY part is the clearer choice when the damaged or worn component is a drive shaft cap. Its title and description identify a composite replacement cap with part number 305241, so the job is narrowly defined rather than centered on the vehicle's tires. The four-cap package also aligns with a repair that calls for multiple replacement pieces.
4PCS RC Crawler Tires win for a wheel-focused refresh
The crawler tire set is the natural match when the work involves replacing tires rather than repairing the drivetrain. It is described for 1.9-inch wheels and names Axial SCX10 ii 90046 and Traxxas TRX4 among its compatible vehicles. The four-piece format makes it relevant to a set-level tire change, while the listed 1:10 scale gives the application another concrete reference point.
Product notes
XRAY 305241 3.5mm Composite Drive Shaft Caps (4)

XRAY 305241 is the practical pick for a narrow repair brief: the description identifies a composite drive shaft replacement cap, part number 305241, with four caps packaged together. Its USD 5.99 listed price keeps the purchase focused when the named replacement part is all that is needed. The limitation is fit scope: the part is described for compatible XRAY RC vehicles using 3.5mm composite drive shafts, so it does not address a crawler-tire replacement. The new, factory-sealed packaging suits a parts-bin repair purchase, but the choice remains tied to that specific drivetrain component.
4PCS RC Crawler Tires for 1.9-inch Wheels

The 4PCS RC Crawler Tires set suits a crawler-focused tire replacement: the description specifies four tires for 1.9-inch wheels with a 90mm outside diameter, and compatibility is named for Axial SCX10 ii 90046 and Traxxas TRX4. At USD 21.00, it is the larger listed-price commitment in this comparison, so it makes sense when a tire-set job is the actual need. Its limitation is fit specificity: the 1.9-inch wheel reference and 1:10 compatible-scale attribute define its intended application. The tires are described as out of original packaging but never used, which may matter if sealed packaging is important.
Final choice by use case
For replacing a composite drive shaft cap on a compatible XRAY vehicle, choose XRAY 305241. It is the direct match for that repair category and keeps the scope to a defined replacement component.
For changing crawler tires on the named Axial or Traxxas applications, choose 4PCS RC Crawler Tires. The four-tire format and 1.9-inch wheel reference make it the more relevant choice for that job. The USD 15.01 listed-price spread matters only after the repair type is clear: the cheaper part is not an alternative to the tire set, and the tire set is not a substitute for the XRAY drivetrain component.
