3 Reasons to Upgrade to the 2009-16 Hyundai Genesis Sedan Main Bearing Set 5M1295H-.25 by ACL

Are you looking for engine bearings that can withstand the challenging demands of competition-level racing? Try the ACL main bearing set 5M1295H-.25. Unlike most factory-equipped engine bearings that feature just two layers of metallic alloys on top of their steel backings, this ACL set has more rigid tri-metal hardened steel backs. They do a better job of handling the intense heat and friction that the powerful engine of your 2009-16 Hyundai Genesis Sedan will deliver during high-speed driving or racing episodes. ACL has been designing performance engine bearings for more than half a century, and so it has [a great deal of experience in this field. In terms of pricing, the ACL main bearing set 5M1295H-.25 will cost you just $225.32. In this article, we will discuss the different benefits of this bearing set, but let us first look into the following:

1. What is the main bearing set?
2. What are three reasons to upgrade?
3. Why buy the ACL main bearing set 5M1295H-.25?

What is the main bearing set?

The main bearings make it possible for the crankshaft to rotate at high speeds within an engine block. These bearings have locating tags, oil holes, and grooves. They also come in two parts; the engine block holds one part while the other is secured in the crank cap.

What are three reasons to upgrade?

Better Lubrication

Your stock main bearings may not be able to cope with your car's upgraded engine output. In your boosted engine, the firing pressure that pushes the connecting rods down on the crankshaft is higher, and so your crankshaft is sure to rotate much faster. The higher rotation speed of the crankshaft will reduce the lubricating effect of the thin oil film between the main bearings and the crankshaft. The crankshaft may end up rubbing against your bearings more, causing intense friction that may tear apart your bearings. Worse still, it may even weld onto the crankshaft and cause catastrophic damage to your engine. These ACL's main bearings are fashioned with extended oil grooves and tapered groove run-outs that ensure a more substantial flow of oil, and they have also been fabricated with standard oil clearance for a stouter oil film. Therefore, you can count on them to keep providing ideal lubrication even with increased heat and friction levels that come with the increased horsepower.

Superior Seizure Prevention

The bearings that come with the ACL main bearing set 5M1295H-.25are far less vulnerable to bearing seizure than the OE bi-metal aluminum-alloy bearings in your 2009-16 Hyundai Genesis Sedan. These bi-metal aluminum bearings operate favorably within predetermined horsepower levels. They are likely to flake or peel under higher engine loads. In extreme cases, their aluminum alloys may soften and melt, and as a result, the crankshaft may seize them. These ACL main bearings have an extra lead-tin-copper overlay that delivers better wear and seizure resistance under high engine loads. Therefore, you will do well to get these ACL race series bearings for your car, especially if you plan to upgrade its performance significantly.

Guaranteed to Last Longer

The ACL main bearing set 5M1295H-.25 is also guaranteed to last longer. These performance engine bearings have tougher high-strength steel backings that will hold up to the pressures of high engine loads for longer. They also achieve increased crush heights that help to boost heat dissipation, delivering more dependable operation for longer.

Why buy the ACL main bearing set 5M1295H-.25?

• ACL has been producing engine bearings and several other automotive products for over eight decades. It has a lot more experience in this field than most of the other engine-bearing manufacturers in the market. The company also has a solid reputation for quality and dependability in the manufacture of all its products.


• The main bearing set 5M1295H-.25 is part of the ACL range of performance engine bearings. It will perform better than basic engine bearings in increased performance or higher horsepower applications.


• This main bearing set is developed at 4722 Danvers Drive, Grand Rapids, Michigan. So, it benefits from highly regulated manufacturing processes that promise high-quality products.
