Timing Components

This collection is the front of the engine: timing covers, timing cover seals and gasket sets, harmonic balancer bolt kits, serpentine belts and a belt tensioner. PRW, SCE Gaskets and Edelbrock supply most of it, with a few parts from Rugged Ridge and Roush.

Fitment leans toward classic Chevrolet and Pontiac vehicles: the Chevrolet Corvette, Chevrolet Camaro, Chevrolet Impala, Chevrolet Monte Carlo, Chevrolet Caprice, Chevrolet El Camino, Chevrolet Bel Air, Pontiac Firebird and Pontiac Grand Prix, along with the Chevrolet C10 Pickup, Chevrolet C20 Pickup and Chevrolet G30. Many of these shared engines, which is why a single part can list a long run of models.

Because of that sharing, buy by engine first and vehicle second. Timing covers are specific to the engine family and sometimes to the water pump: Edelbrock lists some covers in separate versions for a standard or a reverse-rotation pump, and a two-piece cover for LS1 and LS6 engines. SCE Gaskets sells the timing cover oil seal alone or as a timing cover set that includes the seal, listed by engine and displacement. If the cover is coming off anyway, the set saves a second order.

PRW harmonic balancer bolt kits replace the bolt that holds the balancer to the crankshaft. Kits are sold by part number for particular engines, so match the application on the product page rather than going by thread size alone. Rugged Ridge sells replacement serpentine belts for a few diesel engines, and Roush a heavy duty belt tensioner.

Each product page lists the years, makes and models it fits; use the vehicle selector to see only parts for your vehicle. For parts inside the engine, see engine internals; for the rest of the Edelbrock range, see Edelbrock. Priced in Canadian dollars and ships across Canada.

Timing chains and gear sets, belts, tensioners, guides, covers and timing cover seals — SCE Gaskets, PRW, Edelbrock and more, fitting Chevrolet, GMC, Ford and Pontiac vehicles.

Timing components are a maintenance interval rather than an upgrade. A stretched chain retards cam timing and costs power quietly before it fails loudly; a snapped belt on an interference engine bends valves and turns a service item into a rebuild. If an engine is apart for any other reason and the timing set is near its interval, it is nearly always worth doing.

Buy the set, not the part. Chains, sprockets, tensioners and guides wear together, and a new chain on worn sprockets wears to match them within a short time. Replace the cover seal at the same time — reaching it is most of the labour, and it is a common leak point once disturbed.

Most listings here carry verified vehicle fitment, so you can filter to your own year, make and model rather than guessing from a part number.
