NOTE: For the 2001 model year, Porsche replaced the intermediate shaft's roller-type (duplex) chain with a tooth-type chain. This listing is for the later tooth-type chain and is not compatible with earlier engines equipped with the roller-type chain.
While unlikely, it's possible that an earlier engine may have been rebuilt and upgraded to use the newer chain design. For this reason, Design 911 strongly recommends confirming which type of chain your engine uses before placing an order. To assist with identification, our product images include a helpful comparison between the roller-type (duplex) chain and the tooth-type chain.

OEMatch IMS Ancillary Parts — Fit, Function, Confidence
OEMatch IMS ancillary parts for Porsche models support maintenance and rebuilds of the flat-six intermediate shaft and its related systems. This selection covers bearings, seals, flanges, tensioners and housings used to maintain lubrication, alignment and timing. OEMatch supplies a broad catalogue of over 4,000 part numbers and more than 8,700 original-equipment cross-references, with over 100 new products in development.
Available Types
- Bearing kits for intermediate shafts
- Seals and o-rings
- Flanges, housings and spacers
- Tensioners, guides and related fixings
Understanding OEMatch IMS Ancillary Parts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original IMS ancillary parts.
OE (Original Equipment) refers to parts matching original specifications for the IMS ancillary parts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM IMS ancillary parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The intermediate shaft transmits drive and timing loads between the crankshaft and camshafts; its bearings, seals and mountings maintain alignment, control oil flow and absorb rotational forces. Correct selection of these supporting parts is essential to keep timing consistent and to limit wear under high rpm and thermal stress.
Benefits Include
- Restores correct camshaft and crank alignment
- Reduces risk of oil leaks and contamination
- Maintains chain tension and timing stability
Why IMS Ancillary Parts Wear and Fail
- Bearing wear or corrosion leading to misalignment
- Oil contamination that accelerates fatigue
- Hardened or cracked seals causing leaks
- Loss of tension from worn guides or tensioners
The Importance of Replacing with OEMatch IMS Ancillary Parts
Choosing suitable replacements for IMS ancillary parts reduces the risk of timing irregularities and consequential engine damage in Porsche flat-six engines. Replacing worn bearings, seals and guides during maintenance or rebuilds restores oil control and alignment, helping to maintain engine smoothness and reducing the likelihood of costly repairs.
Advantages
- Catalogue coverage for classic and modern Porsche engines
- Part numbers cross-referenced to original-equipment listings
- Options suitable for preventive maintenance and full rebuilds
