The ACL Bearings 6B2390H-.50 Race Series connecting rod bearings are engineered for high-performance and racing applications where durability and precision are critical. These bearings feature ACL's advanced Race Series construction, designed to withstand the extreme loads and temperatures encountered in competition engines.

Key Features:

  • Race Series construction for maximum durability under extreme conditions

Very pleased with my purchase and Autoplicity. Got the best price on the internet and received it very quickly. Product arrived just as discribed. I highly recommend Autoplicity for your on-line shopping needs.

Checkout was easy

Awsome service and prices,Thanks alot

Great prices and super fast shipping. Found my new online parts store!

I was a bit concerned buying from a online retailer I had not done business with before, but Autoplicity is now on my list of preferred vendors. I was sure there would be some problem, as the part I ordered was $73 cheaper than anywhere else online (too good to be true). Well, the part arrived super fast, and was exactly as I ordered. I did not hear from them immediately after ordering, but received confirmation and tracking info when the item shipped, which was two days after ordering. All in all, a great, money saving experience.<br><br>Update:<br>While I am still pleased with the service I received, I find it odd that Autoplicity emailed me and offered me a refund of $5 for writing a review. It has been a couple of weeks since I posted my review, and I have yet to see any credits on my credit card.

I found great prices and they shipped immediately. Best deal online.
