Rimac Spring Tester 0-500lbs 2lb Increments

The PROFORM Rimac Spring Tester 0-500lbs with 2lb Increments is a precision analog valve spring tester designed for automotive engine builders and performance technicians who need accurate compression and tension measurements during valve spring assembly and validation. This specialized diagnostic tool delivers reliable readings across a 500-pound range, making it essential for verifying spring specifications before installation on any engine platform.

The tester's 2-pound increment graduations provide the measurement resolution required to catch out-of-spec springs that could compromise valve timing, cam lobe contact, and overall engine longevity. Whether validating OEM springs during stock rebuilds or confirming high-performance upgrade specifications, the analog gauge delivers immediate visual feedback without battery dependence. The robust construction—weighing 21.5 pounds with substantial footprint dimensions of 15 x 13 x 20 inches—ensures stable mounting and consistent readings across repeated test cycles.

Valve spring testers are non-negotiable for serious engine work. Under-compressed springs can allow excessive valve float at high RPM; over-compressed springs accelerate wear on pushrods, rocker arms, and cam followers. This PROFORM unit is engineered for machine shops, restoration facilities, racing programs, and dedicated enthusiasts who understand that accurate spring force measurement is the difference between a reliable engine and a catastrophic failure. The 500-pound capacity accommodates both light-duty and high-lift performance applications.

PROFORM's reputation in the automotive service equipment market rests on mechanical precision and durability. This spring tester reflects that heritage—no digital circuits to fail, no calibration drift, just honest analog engineering that functions reliably for decades if maintained properly. For engine builders who demand transparency in their validation tools, this represents a time-tested standard in the industry.
