Dual Row RND Roller Bearing IMS Retrofit kit


In stock

SKU: 106-08.4R

The only IMS roller bearing retrofit kit with true thrust control.

Cylindrical bearings provide great lateral load capacity, sacrificing their maximum load cap in thrust (axial movement). That’s why precise thrust control is crucial for bearing’s longevity and reliability. RND Roller Bearing IMS Retrofit kit is the only solution on the market that uses proper heat treated, 52100 bearing steel thrust surfaces on both sides.

Manufactured by RND Engines and distributed exclusively by SSF Auto Parts, RS Roller Bearing Kits sport 2-year/24,000 miles limited parts warranty provided by SSF Auto Parts with professional installation and proper IMS procedure pre-qualification. Recommended service interval 4 years or 50,000 miles.

Why do IMS bearings fail?

  • Lack of lubrication (sealed bearing was used)

  • Insufficient load capacity (factory single row bearing had high failure rate of 8% according to the Eisen class action lawsuit)

  • The factory did not supply a service interval, replacement, or tools for changing the original bearing out – bearing should have had a service interval!

IMS Retrofit as a preventative maintenance:

  • IMS replacement takes an average of 10-14 hours.

  • Typically coupled with clutch and other maintenance.

  • Engine rebuilds take 60+ hours and can cost tens of thousands of dollars.

  • Engines must be pre-qualified prior to bearing replacement.

What factory bearing does my engine have?

  • 1997-1999: This engine featured a dual row bearing IMS

  • 2000-2001: These engines came from the factory with either a dual row or a single row bearing IMS

  • 2002-2005: This engine featured a single row bearing IMS. Some late production 2005 models will have a non-servicable IMS.

  • 2006-2008: These engines were fitted with a larger bearing that is not serviceable without a complete teardown of the engine.

  • If the engine in your car has been replaced, it will have whatever IMS bearing was in production for that model year of manufacture for the replacement engine.

Use IMS Pro Toolkit part number 106-08.13 for installation. No oil system modifications required!
