ACL Race не мягкие, а наоборот более твёрдые чем DuraGlide.
Плюс у них немного другая форма, которая обеспечивает лучший масляный клин на высоких оборотах.
Итого если ставить Race то коленвал сильнее пострадает от частиц в масле(они не войдут в твёрдый верхний слой).
Для дэйлидрайвен лучше брать DuraGlide.

Цитата:
Technically they're both tri-metal. The tensile strength of each bearing is the same. Perhaps this is where the confusion is coming from causing many to refer to the Race series as Tri Metal. ACL has three lines. The AluGlide are a bi-metal bearing. This is a stock replacement type bearing. The DuraGlide are a tri-metal design with higher tensile strength. They retain the excellent embedability characteristics and are excellent for use in modified engines. The next step up is the race bearing but they arent the best for all builds. The two biggest differences are embedability and eccentricity. When your oil gets contaminated with particles, they will become embedded in the softer top layer of the duraglide bearing where they cannot damage the crank. When this happens with a Race bearing, the particles will stay within the film layer which will gouge the bearing and score the crank. The increased eccentricity of the Race series allows for better oiling at higher RPM's and helps prevent "pinching" and distortion of the housing bore.
Each bearing has it's place. All of our street engines get the DuraGlide bearings unless the customer requests the Race bearings.
