shift assist

Small flat bearing that goes under your secondary spring, it lets your secondary spring twist easier for improved upshift and downshift and less wear, I think its worth it. I paid something like 32.00 shipped i think,
It eliminates the spring binding and should help consistancy. Without it you might make a pull and hit 7900 RPM and then make a second pull and it 7700 RPM because the spring was binding. Cat put some plastic washers in there to solve the problem but the thrust bearing (shift assist) works much better.
I bought mine from Ganggreen (not sure if 1 or 2 g's in the middle) on here. $17 or $18 shipped. You will lose some peak rpm's after installing it because it upshifts easier. So you will need to drop some weight in your primary to compensate.
is this something that works with the rkt upgrade as well?
If your using the torsional RKT kit than no, if you are still using just a compression spring then it should work.
yah im running the torsional kit so didnt think it would help.. thanks
Every spring if not let to spin when compressed will belly. This lest the spring spin so the belly will not hang the shift. This will happen in the primary too so if you don't put in a friction shim you need to make the spider cup bigger so the spring can grow.
The cats are animals after you clean this up.

True Story what said above!
The way I look at it if you have one in there it should be good. The spring that is steel and the spider aluminum they tend to stick together and hang. With one shim in there the spring and shim are steel on steel and should spin abit.
I cut my spider open and run one shim.
Here is a before and after look. You can see how much the spring was digging into the spider cup.

Nice, clean job on the spring cup! Where do you get the friction bushing? would a Nylon washer work? I opened up my spring cup but would like to put something in there to cut back on the friction.
I get mine from comet and then have them turned down to 2.06" OD. They are thick like in the .060 range.
If you need a thick shift assist to take up room in the close ended helix here is the part numbers for a auto shop shift assist. You can get the washers in different thicknesses. This seems to let you run the goodwin performance Doo RER springs in the close ended helix.
Roller cage AXK4565-HLA and thick washers for the roller cage is LS4565 Any auto shop store should be able to get them. INA bearings Walzlager. Washers come in different thicknesses and these are cheap but well made.
I am not sure about a nylon bushing. You would then have three different materials in there. We all know how well the hard back one in the secondary worked.

www.hiperf.com sells a shim kit called Glide Washers. It was about $15 and you got 2 shims that had some low friction coating and were made of steel and 3-4 zinc plated shims to fine tune your spring.

Ya this year they have been on intergalactic back order. I think they will get caught up this summer.
Cheers Don.
Did anyone try this bearing/washer setup? Am I understanding this correct in that it is "thicker" than the shift assists you can buy because it also replaces that plastic tapered piece that centers the other shift assists?
