Extended CV Axles - Lets talk about them

I have done a deep drive into the Extended CV Axles needed when doing a lift on the 3rd Gen tundra. Here is what I found. What are they? There are two sets of front CV axles that come stock on the 3rd Gen Tundra. The TRD Offroad packages and the TRD Pro Tundra come with a red set that are over all longer and stonger built for offroad. These upgraded Axles handle more weight and flex than the standard OEM Axles. What is the Difference? SpecStandard CVTRD / Extended CV Length~24.5–25.5"~25.5–26.5" Shaft Diameter~26–28 mm~30–32 mm Joint SizeSmallerLarger Plunge Travel~1.5–2.0"~2.5–3.0" When do you actually need them? This is on a case by case bases but most trucks do not need these extended axles. When using the standard size axles you may get a clicking or CV binding noise when at full flex. Full flex happens most often when you are offroad and you may have one wheel completely off the ground and the other side completely stuffed into the fender. At this point is where you will see the limitation of the CV axle. But 95% of the Tundra on the road today will not see the limitation as also the UCA becomes a binding point before the CV axle does. Other Options Now other than the OEM red TRD axles there are others on the market that are also extended that may fit your needs.

It's not cheap, but in my opinion the Alu-Cab Contour Canopy might just be the best option for bed cap. It's lightweight and durable enough to handle anything I throw at it. What are you running?
