Here is the left Gforce axle next to its OEM counterpart. But this is about more than just strength. According to Gforce, "GM developed the anti-wheelhop technology years ago and we have refined it to further eliminate wheelhop. This has been very successful for us in the GTO, CTS-V, G8, and Camaro markets. The left-hand axle is regular diameter, while the right-hand axle has an increased diameter. The design and material we use is what eliminates the wheelhop."
