A-Premium Ignition Distributor for Chevy & GMC V8 Engines - Black Cap, Direct-Fit for 5.0L–7.4L (1987–1997)

When an aging distributor causes misfires, poor idle, or hard starting, installing a correct-fit replacement saves time and keeps your truck or SUV running as intended. The A-Premium assembly includes a black cap and rotor, and it matches multiple OEM reference numbers so you can replace worn components without modifying wiring or mounting points. It’s designed for a wide range of Chevrolet and GMC vehicles — pickups, SUVs, vans and medium-duty trucks — covering popular V8 displacements used in C/K pickups, Blazers, Camaros, Suburbans, and Kodiak/TopKick chassis.

Which vehicles and engines will this distributor fit?

This unit covers many V8 Chevrolet and GMC applications from the late 1980s through the 1990s, including 5.0L, 5.7L, 6.0L and 7.4L engines. Check the model years and engine family in the compatibility list to confirm fitment for your vehicle. The part cross-references common OEM numbers so you can match it to your factory distributor.

• Fits Chevy & GMC V8s in trucks, vans and SUVs 1987–1997 (see detailed list for models and years)
• Compatible with C/K 1500/2500, Silverado/Sierra families, Camaro, Blazer, Suburban, Yukon and Kodiak/TopKick
• Designed for direct swap using existing mounting and vacuum advance connections

How does this replacement help solve ignition problems?

Replacing a worn distributor restores correct spark timing and distribution to each cylinder, reducing misfires, rough idle, and difficult cold starts. The included new cap and rotor eliminate corrosion, carbon tracking, and worn contacts that degrade spark transfer. You reinstall it like the original part, then fine-tune timing as required by your engine specifications.

• New cap and rotor remove common failure points like cracked insulators and pitted contacts
• Improves spark transfer and reduces chances of cross-fire or weak spark
• Works with existing vacuum advance and mounting hardware for fast installation

What specifications and cross-reference numbers should I check?

Match the distributor by OEM or aftermarket reference numbers printed in your service manual or on the old unit to ensure correct gearing and electrical fit. A-Premium lists many cross-reference numbers included with this assembly so you can verify compatibility before purchase. Also confirm engine displacement and model year ranges against the product’s fitment list.

• Listed cross-references include 110-3952, GM04, HEI652R and many GM OEM numbers
• Ensure engine size (5.0L, 5.7L, 6.0L, 7.4L) and vehicle year match your application
• Verify vacuum advance hookup and connector style against your old distributor

How difficult is installation and what should I expect during service?

Installation is straightforward for anyone comfortable with basic engine work; it usually requires removing the cap, rotor and hold-down, swapping the unit, and re-timing. Expect to set initial timing after installation and clear any trouble codes if present. If you prefer, a professional technician can install and set timing quickly.

• Typical installation: remove spark plug wires in order, unbolt old distributor, transfer any bracketry, install new unit
• Requires timing light and adherence to factory timing specs for final adjustment
• Replacement cap and rotor included to complete the ignition circuit renewal

Who is this for: This A-Premium distributor assembly is for DIY mechanics restoring late‑80s to mid‑90s Chevy and GMC V8s, fleet technicians keeping older trucks reliable, and anyone needing an affordable, correctly referenced replacement to resolve ignition-related drivability issues. Verify your vehicle’s year, engine displacement and OEM reference numbers against the listing before ordering to ensure a proper direct-fit swap.
