Yeah because it's a "body lift" with lifting blocks, the suspension all remains *roughly* at the same angles so theoretically your CV's and bushes shouldn't wear any faster.
Although you will find that they will wear faster anyway - due to the way the car is going to be driven from now on.
When you are driving around offroad (now that you have new found ability with your nice new lift kit) suddenly you are putting your CV's at much wilder angles than you ever have before when sticking to tarmac. This obviously puts more stress on your various bushes in the car and will cause them to wear faster.
As the others have said...once you start getting longer springs etc then your CV's will constantly be at wilder angles so naturally will wear even faster again.
I think it's a general rule these days that if you are going to build an offroading L series you need to develop a few $$ savings skills first, ie;
- learn how to swap driveshafts and rebuild CV joints
- build up a good little stock of spares
- develop your bush mechanic skills
- carry the spares with you at all times
- most importantly carry the tools required to install the spares at any given time!
Hm that ends up sounding pretty negative as far as getting a lift kit........
If you don't flog around offroad every day, and don't get airborne all the time - you shouldn't really have TOO many problems.
Just remember it isn't a monster truck
