Disclaimer: I don’t own the MFC RCV axels. And I have a 2inch lift on my 2017 KL. Not for a mechanic like yourself but for everybody else. The aftermarket axels that MFC sells are only for the front. The CV axels that are most likely to wear out even quicker after a lift are the rear axels. They are shorter, especially passenger, and after lift are immediately subject to more extreme angles. I am hoping that one day there will be a full four piece set for all four CV axels. CV axels break/wear when they are stressed beyond their design and as long as they are at extreme angles they are more likely to break. Keeping the sway bar connected can extend the life of these axels off-road as they prevent extreme angles. CV axels are also likely to break when the wheels are turned, see extreme angles, so if you’re gonna thrash it you’ll want to keep the wheels straight. In the RCV’s case the splines on the ends have stripped on occasion which apparently haven’t been covered by the “break” warranty. This is from the more hardcore community however. Don’t get me wrong, I’d buy them if I could, but not only are they currently sold out, the shipping time when in stock seems to average 6 months. They are better designed than the stock CVs for extreme angles and are made of a stronger material. Jeep likely learned about these issues for the KL when they built their 2014 concept Dakar KL with custom fenders, 33inch tires, custom control arms to fit custom Fox Shocks, and had custom (RCV?) CV axels.
Yeah I've heard about axle problems. I have a Jeep cherokee kl and can't wait to lift and put tires on. They do look a lot better decked out. I just wish they made a better engine. Mine has the 3.2 V6 engine, with bigger tires and all the other stuff it needs a more powerful engine
Pablo at the tire garage lifted my KL but it’s non trailhawk . I’ve got the tiger shark 4 cylinder . I often have it on 3 wheels and performance is surprisingly good . I think you’ll be impressed how well you do with the 6cylider as is and a Dobinson lift . Sand dunes a LOT more fun and worry free now.
If you go past 2 1/2 inch lift, you risk stressing the axles unless they are replaced with a MFC ones. Pricey, but better than snapping an axle offroad haha
I got a lift on my jeep with a 2 inch around , and I think my axle start making noise, took it to the dealer and they blamed the lift and big tires , they want to replace both axle,Ball joint that it has to be replaced with the nockle, and the lower control arm , 6k for everything... insane !!
Just saw your channel tonight on the KL lift. Good stuff!
So what was fix for the rear CV axle noise? It does look nice tho.

Would MFC offroads axles fix that problem? They make theirs to be able to handle the angles.
Wonder if the stiletto rear control arms will help
They would but they don't have the RCV for the rear . For the rear , you'd need the subframe drop.
@@off-roadingexplained8417 couple of well place cuts and welds ought to fix it.

I agree w wanting more power but I think it's made to not compete w the Wrangler. Either way their very capable just like Will says

Lift kits look cool but the suspensions were out faster
