BMW S85 Comprehensive Timing Chain Replacement Kit - 11317833937KT

Product Information

Complete timing chain kit for your E60/E61 M5 or E63/E64 M6

This package provides the essential components to service both the primary timing chain system and the oil pump drive for the S85 V10 engine used in the E60/E61 M5 and E63/E64 M6. It includes chains, guides, tensioners, supporting hardware, and critical seals to restore proper timing accuracy and oiling performance.

Notes:
Fluids are not included. For a complete service, add engine oil, filter, and coolant as required. A dedicated timing toolkit is strongly advised for correct timing and alignment.

Why service the timing system?
The timing chain synchronizes the crankshaft and camshafts so valves open and close at precise intervals. Over time, chains can stretch and guides/tensioners can wear, causing noise, poor performance, or if ignored catastrophic engine damage. Proactive replacement maintains reliability and preserves engine health.

Common symptoms of timing system wear:

• Rattling or slapping noises at start-up or idle indicating chain slack or weak tensioners.
• Reduced performance, sluggish acceleration, or fault codes related to cam/crank correlation.

Assembled by GEMS autocraft:
This comprehensive kit has been curated by GEMS autocraft to provide all the mechanical, sealing, and hydraulic components needed to complete the job in one visit. The selection reflects the exact parts we use in our in-house workshop services, chosen for proper fit and long-term dependability.

Along with the primary components, we include supporting items that experience has shown are best replaced at the same time. This ensures a thorough service, preserves system integrity, and helps prevent repeated labor down the line.

Our approach removes uncertainty and streamlines the process. With every critical part included, the service can be completed correctly the first time.
