HPI Baja Clutch Bell Alloy BJ613 by GPM  [BJ613]

Aluminium clutch bell matched to HPI Baja

The BJ613 alloy clutch bell is an aftermarket replacement that fits HPI Baja RTR models and aims to give stable engagement for off-road applications. The component suits hobbyists working on 1/5 scale driveline maintenance and tuning.

Made from aluminium alloy as noted in the product title, this bell can replace aged steel or cast items to help maintain consistent shoe contact and reduce heat transfer to adjacent parts. The pack contains the mounting screw and lock nut called out in the title to fasten the bell securely to the clutch assembly.

Fitting is straightforward for those familiar with clutch work: remove the stock bell, inspect clutch shoes and bearings, install the BJ613, and secure it using the supplied screw and lock nut. Ensure the bell runs true and spins freely before reassembling to avoid premature wear of gears.

Swapping to an alloy bell will affect thermal behaviour and wear slightly, so consider it as one variable in a broader clutch setup review with springs, shoes and bearings. Regular inspection and correct lubrication will lengthen service intervals.

For NZ-style maintenance routines, the BJ613 provides a durable replacement option for HPI Baja clutch assemblies and pairs well with a full clutch inspection.
