Arent you supposed to ask before you buy?

Yeah... I was just going off the quality of their other products.  I like the idea of the bearing... The "Shift Pro" doesn't look like it has a bearing.

Mine did not last the season! Just saying!

I did it to mine, so far so good it helped a decent bit works awesome with a modded shift star. pretty easy drill the old piece off and bolt that bearing on. not sure how this wouldnt last a season unless something else went wrong.

I have the shift pro kit and it is  a bearing. With the easy spring, modded shift star, and shift pro it shifts nice and smooth but it did make neutral harder to find. You get use to it though. I just rev it up and shift to neutral as the rpms are coming down.

I already have a modded shift star, and modded shift shaft.. I am going to use this to round out my shifting mechanism.. I like Mull parts and this was $20 cheaper than the Shift Pro.. I also heard that the lighter spring on the Shift Pro cause a popping out of gear condition? Is that true? The only issue I can see happening with this Mull kit would be if the bearing breaks up into pieces... I remember these bearings from my RC car days, they work awesome right up until they grenade! LOL With this 4mil i'm building i'm going to need all the shifting help I can get, and I don't want to cut my transmission. I'm also thinking about the billet 2nd gear set, and straight cuts form RDZ.

Good morning guys, I figured I would try to answer any questions on this kit.  The roller bearing that we use is a shielded type that helps prevent any debris from getting in the bearing.  There is very minimal radial load or rpm on thiss bearing so IMO, anything short of lifetime life, I would be suspecting that either something got in the bearing or possibly was assembled wrong. 

 

The attachment components use mechanical locking to prevent them from coming loose but probably a good idea to check on everything whenever thee clutch cover is off.  We did quite a few tests comparing the stock and roller bearing detents and you could certainly feel the difference. Smoothness was most notable. 

 

The shields on the bearing would also work to contain any debris from the bearing but in most any case, the bearing should just lock up and be harder to shift rather than exploding.  Remember that it is not constantly spinning, just glides over the star.

Shift pro has a bearing. It was the first to have one. We did the same conversion that mull does on my buddy's bike and it's nice. I found that their star definitely is a little nicer then a modded stocker.However with the stock shift star modded it tends to work better with a stiffer stock spring, the mull star works way better with the softer shift pro spring.

 

After hearing so many guys say stock springs work better with modded stars, I swapped my shift pro spring out for the stocker with my mull star. I went to the drag races just to get some holes or practice on my TT motor. Man, I was getting spanked by all kinds of shit missing shifts with the stock spring on the Mull star. Even neutral was a bitch to find I yanked the clutch cover and swapped the shift pro spring back on to it and god damn, my tranny was butter again.

 

So stock modded star, use the stock spring

Mull star, definitely a lighter spring.

You would be nuts to swap out for a 2nd gear set and not cut the tranny. That's a lot of tear down and messing with the tranny to swap a part you really don't need for your motor and probably could of spent that money toward a cut tranny that will be a performance increase you would definitely notice.

Maybe if you were 400lbs and launching it on mega paddles you could break 2nd, but really it's not worth your while. With the average 4 mil, I bet you would snap something in the crank before you mess up the tranny gears.
