KELFORD CAMS: Precision Valve Timing for Dominant Engine Performance
Camshafts are the "brain" of your engine's internal combustion process. They dictate when, for how long, and how deep your valves open, effectively managing the engine's respiratory cycle. New Zealand-based KELFORD CAMS has spent over half a century mastering the art of CNC cam grinding. By combining advanced valve motion software with premium materials, they produce camshafts that unlock hidden potential in almost any engine. ATOMIC-SHOP Ukraine is proud to be an official partner, delivering world-class valvetrain solutions to the local racing scene.
In Ukraine, where the tuning culture is highly diverse—ranging from professional drifting to high-stakes drag racing—KELFORD is a trusted name. Whether you are building a time-attack Mitsubishi EVO, a street-prowling BMW, or a high-revving Honda, KELFORD provides the volumetric efficiency required to outperform the competition. At ATOMIC-SHOP, we don't just sell parts; we provide the engineering backbone for your next podium finish.

The Science of Flow: Why Choose KELFORD?
Many novice tuners only focus on "max lift," but the experts at ATOMIC-SHOP know that "area under the curve" is what wins races. KELFORD's proprietary lobe designs focus on opening the valve as quickly as possible without causing instability. This increases the window for air and fuel to enter the cylinder, significantly boosting horsepower and torque. Their use of high-grade chilled iron castings or billet steel ensures that your camshafts can withstand the extreme spring pressures required in modern 1000+ HP builds.
Furthermore, KELFORD is a leader in Beehive valve spring technology. These springs, available at ATOMIC-SHOP, feature a smaller top diameter to reduce the weight of the retainer and the spring itself. This allows for higher RPM limits and prevents "valve float"—a condition where the valve fails to follow the cam profile, which can lead to catastrophic engine failure under high boost.

FAQ: ATOMIC-SHOP Insights on KELFORD Products
Is ECU remapping mandatory after installing KELFORD cams?
Yes. Since you are fundamentally changing the engine's volumetric efficiency, the air-fuel ratios and ignition timing must be adjusted. ATOMIC-SHOP highly recommends a professional dyno tune to ensure your engine runs safely and makes the most of the increased airflow provided by KELFORD CAMS.
What is the difference between "Drop-in" and "Race" cams?
Drop-in cams (Stage 1) are designed to work with your factory valve springs and ECU limits. Race cams (Stage 2 & 3) feature more aggressive profiles that require stiffer springs to keep the valvetrain in control. ATOMIC-SHOP can help you decide which path is right for your budget and goals.
How do I ensure long camshaft life?
Proper break-in is the key. Use a high-zinc break-in oil and follow KELFORD's specific start-up procedure. ATOMIC-SHOP specialists remind you that the first 20 minutes of a new camshaft's life determine its longevity. Always check your valve-to-piston clearances during assembly to avoid mechanical interference.
