Prox Crankshaft Bearing Set for KTM SX-F 250 13-15 & SX-F 350 11-15

Prevent serious engine damage and bring your KTM SX-F 250 (2013-2015) or SX-F 350 (2011-2015) back to life with the ProX Crankshaft Bearing Kit. This complete crankshaft bearing and seal kit is specially developed for the 250cc and 350cc 4-stroke models from those years and is the ideal solution for a crankcase overhaul, bottom-end rebuild or preventive maintenance.

ProX Racing Parts supplies high-quality parts that often outperform original equipment. This set includes two precision crankshaft bearings (main bearings) from top manufacturers such as Koyo or NTN, plus all the matching crankshaft seals for a fully leak-free installation. The bearings are manufactured exactly to OEM specifications, offer excellent heat resistance and are built to withstand the high RPMs and heavy loads of these powerful 4-stroke motocross engines.

Worn crankshaft bearings quickly cause play, humming or rattling noise from the crankcase, vibrations and oil leaks. This can lead to costly damage to the connecting rod, piston and entire engine. With this ProX kit you can quickly install a tight, smooth crankshaft that produces less friction, runs better and significantly extends the service life of your engine.
