"Ultimate Class" 350-XLT Kit - All Parts Required For Small Diameter Rotating Assemblies

"ULTIMATE CLASS" 350-XLT KIT, INCLUDES ALL PARTS REQ'D FOR SMALL DIAMETER (5.8") BILLET ALUMINUM ROTATING ASSEMBLY, (REQUIRES COAN FRONT AND REAR PLANETS SOLD SEPARATELY).

The Coan Racing 3SP‑1328100 “Ultimate Class” 350‑XLT Kit is a high-performance upgrade kit designed to transform your TH350 into a compact, lightweight powerhouse. Centered around a precision-machined 5.8‑inch billet aluminum rotating assembly, this kit eliminates excess internal weight between the pump and center support. Constructed with ultra-rigid materials, it ensures exceptional structural integrity and rapid hydraulic response, making it ideal for serious drag and bracket race applications. Although the kit contains all rotating assembly components needed for installation, the front and rear planetary gear sets must be purchased separately to complete the build.

This “Ultimate Class” kit reflects Coan's commitment to delivering elite-tier performance, offering racers a race-ready foundation for building a small-diameter TH350 that delivers quick throttle engagement, reduced internal inertia, and pro-level durability on the track.
