Fel-Pro Crankshaft Seal Kit for 1996–1999 Chevrolet K1500 - BS 40656, Front & Rear OEM-Matched Seals

This kit provides replacement crank seals that match the original equipment specifications and materials used for reliable sealing in older GM small‑block installations. Fel‑Pro designs its repair parts to meet fit, form, and function expectations for technicians and DIYers working on classic truck engines. The seals are validated for compatibility and durability to help prevent oil leaks that can lead to messy bays and wasted fluids.

How does this seal kit match the original parts on a K1500?

Fel‑Pro engineers the BS 40656 kit to the same dimensions and material properties that the factory used, ensuring proper seating and shaft contact. That reduces the risk of premature failure due to incorrect fit or wrong elastomer compound. The result is consistent sealing behavior across operating temperatures typical of late‑90s Chevy V8s.

• OEM‑matched diameters and lip geometry for correct shaft engagement
• Heat‑ and oil‑resistant elastomers suited to older GM engine oils
• Validated fit, form, and function to minimize installation adjustments

What should I expect during installation of these crankshaft seals?

Installation requires clean surfaces, the correct seating tools or press, and care to avoid cutting or rolling the sealing lip. The kit is designed for a direct swap where the crankshaft and housing are accessible; follow service manual torque and alignment specs. Proper installation avoids leaks and reduces the chance of accelerated wear on the new seals.

• Direct-replacement dimensions simplify removal and refit
• Use of a seal driver or gentle press ensures even seating
• Inspect shafts and housings for nicks, burrs, or excessive wear before fitting

Will this kit fit my vehicle and how do I confirm compatibility?

BS 40656 is specified for a range of GM and related vehicles from the late 1990s; always confirm fitment with your vehicle's year, make, model, engine, and trim level. Check any fitment notes or qualifiers provided by the seller and compare the OEM part numbers if available. If in doubt, reference your service manual or consult a parts professional to avoid returns or misfit parts.

• Check vehicle year, make, model, engine, and trim before purchase
• Compare kit dimensions and part numbers with original seals where possible
• Contact parts support for fitment clarifications when needed
