What does 'standard size' mean for these bearings?

Standard size (STD) bearings are meant to be installed on a crankshaft that is still at its original factory diameter. If the crankshaft has been machined undersize due to wear or damage, you would need a different size bearing set.

Do these bearings come with new bolts?

This listing is for the connecting rod bearing set only. New connecting rod bolts are often recommended or required when replacing bearings, as they can stretch during installation. Please check your vehicle's service manual or consult a mechanic.

How do I know if I need standard size bearings?

You should use standard size bearings if your crankshaft journals are within factory specifications and have not been machined undersize. If you are unsure, it's best to measure your crankshaft journals or consult a professional mechanic before ordering.

About this part

Product Details

ACL has been making engine bearings for decades, and this connecting rod bearing set for your 2004-2006 Chevrolet Colorado or GMC Canyon is one of their staples. These bearings are critical for the health of your engine's rotating assembly. They sit between the connecting rod and the crankshaft, providing a smooth, low-friction surface that allows these high-speed, high-load parts to move together without seizing.

This set is a standard size (STD), meaning it's designed to fit a crankshaft that's still within its original factory tolerances. If your crankshaft has been previously machined or ground undersize due to wear or damage, you would need a different size bearing. ACL uses well-built materials and manufacturing processes to ensure these bearings can handle the demands of daily driving and occasional harder use. They are a solid option when you need to replace worn-out bearings during an engine rebuild or repair.
