Are you setting up a new unit or moving your treadmill and missing the essential assembly bolts?
The 2023–Current Spirit XT385 (SN 385823+) features a refined steel frame and the updated Safeguard 360™ structure. Because this generation uses specific metric threading and high-tensile hardware to support its 375-lb user capacity, using "close-enough" bolts from a hardware store can lead to frame squeaks or dangerous instability. Our Genuine Spirit XT385 Hardware Kit is the complete factory-spec package, organized by assembly step to ensure your treadmill is as rock-solid as the day it left the warehouse.
This kit is divided into labeled sections that correspond directly to the XT385 Assembly Manual, ensuring you have exactly what you need for each phase of the setup.
Upright & Stability Hardware: Includes the heavy-duty M8 x 60mm and 80mm Socket Head Cap Bolts required to anchor the massive steel uprights to the frame base.
Console & Handlebar Fasteners: Features the 5/16" and M5 Button Head Bolts designed for a flush, professional finish on the console mast and the new rocker-style handlebar controls.
Specialized Washers: Contains the essential Nylon Dished Washers and Star Washers that prevent bolts from backing out due to the vibrations of high-speed running.
Essential Assembly Tools: Comes complete with the Combination M5 Allen Wrench/Phillips Screwdriver and the M6 L-Allen Wrench, so you don't have to hunt through your toolbox.
The XT385 is a heavy machine (286 lbs). The integrity of the folding mechanism and the Lift Assist cylinder depends on the use of specific high-grade fasteners. This kit uses Grade 8 equivalent hardware with pre-applied thread-locking compound where necessary. Using non-OEM hardware can void your Lifetime Frame Warranty and lead to "shearing" under the stress of 12 MPH sprints. This kit ensures that every joint is tight, quiet, and safe
