WE DON'T SELL THE LIFESTYLE
WE LIVE IT

NHRA Records

Bobby Wood holds two NHRA national records. We didn't build a brand around speed — we built it because we are fast.

Made in the USA

Every Knight Prowler® cam is machined in the United States to Bobby's exact specifications. No offshore shortcuts, no compromise on tolerances.

Dyno Proven

Every spec is proven on the dyno before it goes on a bike. High torque, high lift, unmatched horsepower numbers — verified, not estimated.

Road Tested

Thousands of real road hours logged by Bobby himself. Every cam design lives in the real world before it ships to yours.

From the Riders

WHAT THE BUILDERS SAY

★★★★★

"I've installed a lot of cams over the years, but the Knight Prowler specs are something else. The torque hit right where my customer needed it. Couldn't be happier with the results."

Lee Bomar

Master Harley Technician · InDepth Customs

★★★★★

"Dropped these in my Twin Cam 103 and the difference on the highway is night and day. Pulls hard from the bottom and never stops. Bobby Wood knows what he's doing."

T. Kowalski

Street Rider · Chicago, IL

★★★★★

"I run the Mickey Cohen cams in my build shop now. Customers love the performance, and I trust the brand. When Bob Wood designed it, I knew it was legit."

R. Sandoval

Custom Builder · Phoenix, AZ

★★★★★

"Milwaukee-Eight cams from Wood Performance completely changed how this bike rides. More grunt off idle, more pull on the freeway. Best mod I've done to this bike, period."

D. Marcello

2019 Road Glide Owner

★★★★★

"Ran a dyno before and after. The Wood Performance cams added 18 lb-ft of torque to my Evo build. Numbers don't lie, and neither does how this bike feels under you."

W. Jackson

Evo Softail Builder

★★★★★

"Ordered the Twin Cam cams for a customer build. Shipped fast, quality is excellent, and the fit was perfect. Bob Wood has been doing this forever and it shows in every detail."
