Product Details

WAI DST1875 is a complete ignition distributor assembly designed for 1981-1986 Chevrolet and GMC vehicles with vacuum advance, including Chevrolet C10, C20, El Camino, G10, G20, K10, K5 Blazer, and GMC C1500, C2500, G1500, G2500, Jimmy, and K1500 applications. This part number also cross-references 1103464 and 1103465 for the same application. The distributor uses a melonized steel gear, aluminum housing, and pick-up coil design to support reliable ignition timing and consistent spark delivery in the listed GM platforms.

Part number DST1875 is a practical replacement choice when servicing older Chevrolet and GMC ignition systems that require a complete distributor assembly. It is also listed for Chevrolet K10 Suburban, K20 Suburban, GMC C1500 Suburban, GMC C2500 Suburban, and GMC K1500 Suburban applications with vacuum advance.

What It Helps Fix

• Hard starting caused by worn distributor components
• Misfire or rough running from inconsistent spark timing
• Ignition scatter related to distributor wear
• Weak or unstable ignition output from aging internal parts
• Cap and rotor wear in older Chevrolet and GMC ignition systems

Installation Notes

Verify engine application, vacuum advance setup, and gear compatibility before installation. The distributor is a direct-fit replacement for the listed vehicles, but ignition timing should be checked after installation to confirm proper engine operation. Use the included cap, rotor, and coil as supplied with the unit.
