What does '0.25mm oversized' mean for these bearings?

This means the bearings are manufactured to be 0.25mm larger in diameter than standard size. They are used when the engine's crankshaft has been machined (ground) down to a larger size during a rebuild to correct wear or runout.

Do these bearings come with installation hardware?

This set includes the main bearings only. You will need to reuse your original main bearing cap bolts or purchase new ones separately, as they are not included with the bearings.

What is the typical application for these high-performance bearings?

These bearings are intended for performance-oriented engine builds, such as those with forced induction (turbochargers or superchargers) or significant modifications that increase engine stress and heat beyond stock specifications.

Product Details

Already running a built SR20DE or SR20DET engine? This high-performance main bearing set from ACL is the next piece of the puzzle. These bearings are designed to handle the increased stress and heat that comes with a performance engine build, ensuring the crankshaft stays properly supported under demanding conditions. They are precision-made to meet the tight tolerances required for optimal engine function and longevity.

ACL has a solid reputation for making well-built engine components, and this main bearing set is no exception. Each bearing in the set is 0.25mm oversized, which is crucial if your crankshaft has been machined to a larger size during a rebuild. This specific sizing ensures a perfect fit and proper oil clearance, which is vital for reducing friction and heat buildup. Using the correct oversized bearings prevents premature wear and potential engine damage, especially when you're pushing the engine harder than stock.

When you're rebuilding or modifying your SR20 engine, using the right internal components is key. This ACL main bearing set is a popular choice for enthusiasts looking for reliable performance. Make sure to consult your engine's service manual for the correct installation procedures and torque specifications to ensure these bearings perform as intended.
