About Hot Cams
Hot Cams has been a cornerstone of the powersports performance community since 2001, built from the ground up by enthusiasts who actually ride. Part of the C&L Companies family of powersport brands, Hot Cams was founded by avid dirt biker Curt Leaverton with a singular mission: to give riders more power, more torque, and more confidence on the trail or the track. Every product in the Hot Cams lineup is designed by people who live and breathe powersports — and then tested on their own dirt bikes, ATVs, and UTVs before it ever reaches a customer.
Built for Performance, Proven on the Trail
At the heart of the Hot Cams catalog are their industry-renowned engine camshafts — the upgrade that started it all. Available in multiple stages, Hot Cams camshafts are engineered to improve intake and exhaust duration, helping your engine breathe more freely and produce meaningful gains in both acceleration and peak power. Stage 1 grinds are tuned for improved torque in the lower and mid RPM range, Stage 2 cams push upper-range horsepower, and Stage 3 profiles blend the best of both worlds for all-around performance. Each camshaft is machined from premium billet steel, case-hardened for durability, and dyno-validated at C&E testing facilities in the USA.
Hot Cams camshafts have been featured in leading dirt bike and ATV publications and have earned consistent recognition as a top-rated product in the powersports aftermarket. Their broad fitment coverage spans the most popular brands in off-road riding, including Honda, Yamaha, Kawasaki, Suzuki, KTM, and Polaris — making it easy to find the right cam for your specific make and model.
A Complete Valve Train Ecosystem
Beyond their signature camshafts, Hot Cams offers a comprehensive suite of valve train components that work together to maximize engine reliability and performance. This includes cam chains engineered with exclusive heat treatment for reduced stretch, mechanical cam chain tensioners that eliminate the start-up noise and timing-jump risk associated with OEM hydraulic units, and tappets built to exceed factory tolerances.
Precision at the valve level is just as important as cam profile, which is why Hot Cams also produces a full range of engine valve spring shims and engine valve adjuster shims — essential for setting exact valve clearances after a camshaft installation or routine engine service. With one of the largest shim selections available in the powersports market, Hot Cams makes dialing in proper valve clearance straightforward and precise. Riders looking to go further can also explore the brand's engine exhaust and intake valve kits, which pair seamlessly with a Hot Cams camshaft upgrade for a complete top-end refresh.
