Stock YXZ drive shafts are known to have a couple issues, with the more serious ones being broken welds and stripped drive couplers that can leave you in front wheel drive mode...
The Avenger Motorsports driveline kit replaces all of that with a larger, stronger driveshaft made from higher quality materials, and a sealed CV joint that you'll never need to worry about.
When we decided to turn the power up big time on our YXZ this was one of our key driveline upgrades, and it has taken everything we have thrown at it (which is a lot...).
In addition to the durability improvements it also eliminates the majority of the lash in the stock driveline and reduces clunking during shifts significantly.
