When choosing RC repair tools & parts, the key question is whether you are fixing a focused drivetrain issue or refreshing a crawler's tire setup. XRAY's replacement caps and HOBBYSOUL's crawler tires are not interchangeable solutions, so the right choice depends first on the repair area, then on fit and price.
Quick verdict
Choose XRAY 305241 3.5mm Composite Drive Shaft Caps for a targeted repair involving compatible XRAY RC vehicles with 3.5mm composite drive shafts. Choose HOBBYSOUL 1.3-inch Griptrek Crawler Tires when the job calls for crawler tires designed for 1.3-inch beadlock wheels. The XRAY part is a small drivetrain replacement, while HOBBYSOUL is a complete tire-format change for a crawler setup.

Product notes
XRAY 305241 3.5mm Composite Drive Shaft Caps
A clear reason to choose XRAY 305241 is the narrowly defined repair role: composite drive-shaft replacement caps sized for 3.5mm shafts. Four caps are packaged, and the part number matches the product title, making it a straightforward choice when that specific replacement is needed. The factory-sealed packaging and New condition also suit a planned maintenance job. The limitation is scope. The title identifies caps rather than a complete drive-shaft assembly or a general-purpose repair kit, so this part depends on an XRAY RC vehicle using the stated shaft format. It addresses a drivetrain repair, not a crawler tire change.
HOBBYSOUL 1.3-inch Griptrek Crawler Tires
HOBBYSOUL is the more relevant choice for the wheel-and-tire side of an RC crawler project. The tire format is described as 72mm tall by 28mm wide, with the product title identifying a 1.3-inch Griptrek design. The soft, sticky compound and irregular triangular tread provide concrete reasons to consider it for the mud, loose dirt, and slick-rock situations named in the description. Its limitation is format specificity: the tires are designed for 1.3-inch beadlock wheels, and the stated 72mm by 28mm dimensions need to match the intended setup. This is a focused tire choice, not a replacement part for a drive shaft.
Final choice by use case
For XRAY drivetrain maintenance, choose XRAY 305241 3.5mm Composite Drive Shaft Caps. The $5.99 price, composite construction, and 3.5mm shaft reference align with a specific cap replacement. For a crawler tire refresh, choose HOBBYSOUL 1.3-inch Griptrek Crawler Tires; the $36.26 price reflects a different type of purchase, with the tire format and beadlock-wheel fit taking priority. Since the listed prices are $30.27 apart, compare the repair job rather than treating these as direct substitutes.
