Try talking with Dan at Kershawdesigns.com. He may be able to help you with the drive shaft/axles that you need, or even make something up for you. Personally speaking plastic is just what it infers, and plastic toys were made for boys. If you want to beef up your truck by putting more power then was originally installed by the MFR, plus adding extended arms, offset rims, and such, then why try depending on plastic parts to drive the modifications? Once you modify the power plant or the drivetrain in any way you might as well take a very close look at the rest of the truck and anylize what you have done. Surely there will be more weak lincs that need to be modified/upgraded in order to truly make the vehicle Bombproof as you wish.

Bottom line, you can either purchase plastic parts and routinely replace them due to breakage or bad driving, or upgrade your vehicle engineering wise making good purchases up front ONCE, and enjoy having fun with your truck knowing that it will hold up to just about anything you throw at it. All of this is contingent upon your use of the vehicle, wheather you are ROAR racing or bashing your vehicle in yoru own backyard. How many real life size vehicles do you see using composit plastics in the drivetrain?? Size to weight ratio these vehicles are under the same stresses and should be engineered in the same manner. Sure you can use plastic driveline parts all day long and maybe it will hold up for a while, but in the back of your mind you are still going to be thinking about wheather or not it will hold up, which will affect your willingness to go full throttle and really push your truck the way you would like. RC Alloys.com also does custom drive shaft work on request. Have fun and good luck with your decisions. Spend your money wisely, but realize that this hobby is not cheap by any means. You are going to spend big money over the long haul no matter which way you go with this project.

I have to think you have something else going on here. What kind of "wear" did you see that made you concerned? Are the shafts rubbing on the arms? Did you change your rockers and pushrods to the correct ones for use with the extended wheel base arms? (you can't use the LT's with those, right?). You have a symptom that may or may not be resolved with higher priced CVD's, but you may also end up spending that money and still have the issue.

BTW: If you have seen any of Jerry's stuff, he has an extreme allergy to anything plastic!!!!

I have been running my revo with all its plastic day in and day out on 6S, and they have been holding up better than my metal CVD's did.
