If you have a seized engine, or are looking to overhaul or rebuild your engine, don’t forget to replace your crankshaft. Crankshafts rarely break, but considering that they are such a major component of your bottom end, they can cause a lot of damage if they do. At Rocky Mountain ATV/MC, we carry durable, quality crankshafts to get your engine running strong again in no time.
We carry full crankshaft assembly kits and connecting rod kits that are built to OEM specifications and designed to meet or exceed OEM performance. Our kits from Hot Rods and Pro-X are designed to last the lifetime of your ATV when properly cared for.
If you would like a stock crankshaft instead, be sure to check out the OEM section of our website to get the original manufactured crankshaft and any additional accessories that you may need. Check out our selection of crankshaft and connecting rod kits for your ATV today!

Make your YZ a true off-road weapon! I switched bikes from a KTM 300XC with a 6 Speed to a YZ. My only complaint was the YZ needed a 6 speed. I have a friend that changed the gears in his YZ and loves it so I changed mine. I no longer have any complaints with the Bike. This is not need for the MX track but for desert riding and racing it’s awesome!Read All Reviews
