2-1/16in C/S Oil Pressure Gauge 0-100psi

The 2-1/16in C/S Oil Pressure Gauge 0-100psi is an essential instrument cluster upgrade for any serious engine builder, hot rod enthusiast, or performance mechanic. This mechanical oil pressure gauge replaces factory warning lights with real-time analog readouts, giving you critical visibility into engine health during dyno pulls, street driving, or track sessions. Whether you're running a carbureted engine swap, a turbocharged build, or monitoring a freshly rebuilt motor, this gauge delivers the precision feedback necessary to catch oil pressure anomalies before they become catastrophic engine damage.

Engineered with a 2-1/16-inch case diameter, this oil pressure gauge fits most aftermarket dash panels, custom gauge clusters, and roll cage-mounted instrument arrays standard in street rods and race cars. The 0–100 psi range spans typical street engine pressures (40–80 psi at idle and cruise) while accommodating high-performance and forced-induction engines that may spike into the 60–100 psi range under load. The chrome steel case construction resists corrosion and vibration typical of engine compartments, while the mechanical Bourdon tube movement ensures accuracy without electronic interference—a critical advantage in vehicles with high-output ignition systems or extensive electrical modifications.

Mechanics and fabricators commonly install oil pressure gauges on LS swaps, small-block Chevy builds, vintage truck restorations, and any engine where factory instrumentation is absent or unreliable. Installation requires a simple 1/8-inch NPT sender connection at any open oil gallery or pressure line, making it compatible with virtually any engine platform. The compact 4.75 x 4.5 x 5.05-inch footprint accommodates tight dash openings, and the lightweight 0.87 lb design minimizes stress on mounting brackets. For those demanding transparent, real-time oil pressure monitoring—without relying on dashboard warning lights—this 2-1/16in C/S Oil Pressure Gauge 0-100psi delivers the dependable mechanical performance that separates informed builders from guesswork.
