If you're planning to run at high RPMs and with big boost, you won't have to worry about fatigue, stress wear, or failure when using ACL's top - grade metallurgy. When ordering bearings, remember that engine bearings need proper tolerance measurement before purchase. If you're unsure about the bearing size for your engine build, consult a professional engine builder. We can't accept returns or exchanges for incorrectly ordered bearings or any engine internal components. When working on rods and pistons, it's a smart move to replace the rod bearings too.

Using these ACL rod bearing sets is straightforward. When you're replacing rods and pistons in your Nissan 350Z VQ35DE from 2003 - 2006, simply swap out the old rod bearings with these new ones. But here's the important part: before you buy, have the proper tolerance of your engine measured. If you're not sure how to do it, talk to a professional engine builder. This will ensure you get the right size bearings. As for maintenance, these bearings are built to last. Thanks to their special coating and high - quality metallurgy, they can handle tough conditions like high RPMs and big boost. However, keep an eye on your engine's performance. If you notice any strange noises or changes in how the engine runs, it might be a sign to check the bearings. Also, remember that we can't take back or exchange incorrectly ordered bearings, so double - check your order before finalizing it.
