Replaces OEM 8990/A style ball bearing. This bearing will fit will fit all models as front & rear outer cam bearings. Note: The MoCo has redesigned the Twin Cam rear outer cam bearing from ball to a roller bearing style in 2001. This was done to help prevent failing ball bearings on, specifically, rear (=driveside) cams that are heavier loaded. This 01-up roller style bearing is a 3-piece design that is more heavy duty than the roller bearing. No other parts changed during the bearing changes. The early 99-00 style ball bearings will still fit all 99-06 models front & rear. Using front & rear ball bearings present no issues on cam driven gears.
Fits: > 99-06 Twin Cam (excl. 2006 Dyna) (NU)

When still present it is advised to replace the low cost OEM needle bearing in 92-99 Evolution Big Twin models marked 'INA SCE 138 USA' with a 'full needle' bearing to increase reliability. Especially important when using higher lift cams, which increases stress in the camshaft bearing.

Cam lifts in Evolution heads (1.65:1 rocker ratio) are higher than in S&S Panhead or Shovel heads (1.5:1 rocker ratio). This results in an approximate 9% lower valve lift in S&S Shovel or Panhead engines. Spring spacing required.
