1996-2007 GM Truck Camshafts

At Thunder Racing, we are proud to carry a broad selection of camshafts from the top manufacturers in grinds ranging from very streetable to all-out race. From mild to wild, we've got a camshaft in the power-range that you are looking for. If you are unsure which application would be right for you, please call our technical department at 225-754-7223 so we can discuss the different options that are available and make sure you get a camshaft grind that is best matched with your application.

For those looking for the ultimate in performance, Thunder Racing has select camshafts that utilize more aggressive lobes than standard "off-the-shelf" LS- series cams. The lobe profiles on these camshafts are engineered for maximum "area under the curve." This means that for a given duration and lift, the lobes on these cams will hold the valves open longer, translating into more power than a standard camshaft lobe in the same RPM range. Please call if you have any questions regarding these camshaft applications.   If you don't see what you are looking for below, please give us a call!

Thunder Racing takes the confusion out of ordering a camshaft for your engine by grouping the necessary items into packages.  If you need assistance with cam selection, please contact our sales department.

What are YOU looking for in a camshaft?


If you chose E, we'd like to introduce you to our newest line of Thunder Racing custom camshafts that are designed to do just that. We've tested these cams in everything from a daily-driven LS1 GTOs to 6.2L Corvettes, and the results have been impressive! These cams are designed for stock-stroke cathedral or rectangular port heads, and with 4 levels of power-making-idle-loping-tire-frying-daily-driver cams to choose from, we are sure there will be one to bring out the TRuTorq in your car too! If you are in the area, feel free to stop by our shop to hear the TRuTorq level 1 cam in Angie's G8.

Thunder Racing began designing LS1 camshafts in 1998, and our cams have proven to be some of the most reliable power-makers on the block.  Although camshaft sizes have gotten more aggressive over the years, these cams are tried-and-true in a variety of applications, with the perfect mixture of power and drivability.  If you need assistance with cam selection, please contact our sales department.

Thunder Racing's CheaTR series of camshafts were developed with the "stealth" factor in mind.  These cams provide broad-range power while still maintainging a stock-like idle and excellent street manners.  The versitility of these cams allow them to work great with stock manifolds or headers, and with or without a torque converter.  They also work well with forced induction and nitrous applications.  If you need assistance with cam selection, please contact our sales department.

Ready to race? Our lineup of max-effort power cams is a great choice for stock cubic inch combinations.  These cams will require gears, converter, and tuning,   If you need assistance with cam selection, please contact our sales department.
