WrenchConnected is an independent installation marketplace operating in partnership with Diesel Power Products.
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.

Colt Cams develops high-performance camshafts and valvetrain components for diesel enthusiasts who demand more from their engines. With a focus on performance-driven camshaft profiles for Cummins and Ford Powerstroke engines, Colt Cams combines extensive research and development with real-world dyno testing to create camshafts designed around the needs of today's diesel performance builds.
Rather than simply modifying existing camshaft profiles, Colt Cams has invested heavily in developing application-specific grinds. Their research has included dyno testing more than 50 combinations of camshaft durations, lobe separations, and installation centerlines to determine profiles that deliver meaningful improvements in airflow, efficiency, drivability, and performance.
Colt Cams offers performance camshafts for some of the most popular diesel platforms, including 5.9L and 6.7L Cummins, 4BT Cummins, 7.3L Powerstroke, and 6.0L/6.4L Powerstroke engines. Whether you're building a daily-driven truck, tow rig, work truck, or dedicated performance engine, Colt Cams offers profiles ranging from mild drop-in upgrades to aggressive competition-oriented camshafts.
Popular Cummins options include the Stage 3 "Big Stick," Stage 4, and Stage 5 camshafts. The Stage 3 "Big Stick" is designed to provide strong mid-range torque and horsepower while maintaining low-end response and drivability, while the more aggressive Stage 4 and Stage 5 profiles are designed for higher-performance applications.
A camshaft is one of the most important components in determining how an engine breathes and where it makes power. Colt Cams focuses on optimizing valve timing to improve the movement of air and exhaust gases through the engine. Depending on the application and camshaft profile, these improvements can contribute to better turbocharger response, reduced exhaust gas temperatures, improved efficiency, and increased power potential.
Colt Cams also pays close attention to durability. Their performance camshafts are engineered for demanding diesel applications, with profiles developed around the specific characteristics of each engine platform rather than relying on a one-size-fits-all approach.
