Comp max lift BSR vs CHE

[ZOOMSS]

So I'm looking at a trunion upgrade for my car and I know CHEs have a solid reputation but recently had a guy recommend the max lift solid shaft system to me but I'm not familiar with solid shaft designs and what their benefits are. I was wondering if anyone had any experience with this and if they'd educate me a bit on them. I'm a bit leery of Comp considering their dip in general quality due to offshoring a good bit of their stuff, and was also wondering if these use needle bearings like their trunnion upgrade does, as those would be my two main concerns about it.

Not sure about the BSR, but I swapped out my Smith Brothers to the CHE's at 27k miles and am very happy with the CHE's. It actually made the valve train a lot quieter!!

I too am considering a shift to a shaft system when I do my 25k spring refresh, among other things. I am very curious to see how my CHE bushings have held up so far.

The latest version of the LS Comp Max Lift BSR system looks to be very nice, and it uses a BUSHED system instead of needle bearings, which is a win for me. The price also seems pretty good for an entry level shaft system. I haven't really seen any reviews on them yet though. BTR also has a shaft mount system, but they use needle bearings, which I want to stay away from - but they are nearly half the price of the Comp system. Another big difference between the two is the BTR setup re-uses your own rockers, while the Comp system comes with all new rockers.

Zoom, the main benefit of a shaft mount system is it greatly increases durability, rigidity, and reduces valvetrain flex, which in turn reduces friction. We want to keep that flex out of the valvetrain as it can cause loss of expected valve lift (ie, less power), increased valve sweep across the valve tip, and other instabilities.

Just keep in mind this is only one of the components of the LS valvetrain that can be improved on. It can get expensive very quickly.

Awesome stuff there brother!!
