Traction And Strength for 2001 to 2010 GM Pickups
Off Road Unlimited installs a Yukon Grizzly locker and RCV Performance Pro 4 CV joints
Let's say you're an '01 to '10 GM truck owner who's found all the power you need. The next step is getting it to the ground-reliably. Off Road Unlimited in Burbank, California, showed us how to do just that by installing a Yukon Grizzly locker in the rear axle for traction and RCV Performance outer CV joints up front for strength.
Since the '88 model year, GM guys have been ridiculed for their independent front suspensions (IFS). Many truck enthusiasts are skeptical of CV joints and A-arms, as compared to the solid axle and U-joints that Dodge and Ford offer. The truth is, CV joints offer a strength advantage over U-joints because CVs offer six surface areas (steel balls) for transferring power, while U-joints only have two (bearing cups).
If your truck spends most of its life on the road, an independent front suspension (with CV joints) offers an advantage over a solid axle because IFS is superior when it comes to isolating wheel movement. We've also seen these setups excel during sled pulling, drag racing, and off-road racing, so their reputation of being weak is starting to fade. Still, those who swear by solid front axles for their ruggedness and off-road capability can also benefit from RCV Performance CV joints by replacing their old U-joints with RCV parts, too.
