Default clutch upgrades???

I am putting a SH28(I think this is what I am going with) on my Savage 21. I am going with 17/49 gearing. What should I do about my clutch? Can it handle the extra power? What all parts of the clutch should I change? Shoes? Flywheel? Please help!

Hi there, i can recommend the Mugen allu clutch, it's very hard wearing, and gives great performance.

If you buy the Mugen clutch, you will also need to buy springs seperately, or you can use the stock clutch springs, i use 1.0 springs in my trucks, also it's best to use the Mugen engine nut, as this will allow the springs to seat properly.

I have three 4.6's, and i run them all with this set up, and no complaints, i have the part numbers if you need them?, but i'm off to work right now.

I run the Mugen shoes in my SH.28 and Collari.32 with no complaints. I tried the 1.1 springs but found they were too heavy for bashing.

I have the Nova Racing aluminum clutch shoes and have been pretty pleased with them, I also use the stock springs.

I hear that the Werks system is very good, but very hard to fit properly. Experience and extra parts are definitely a requirement for the job.

Rumor has it that OFNA wear down very quickly, due the type of aluminum they use for the shoes.

Mugen and Nova shoes seem to last pretty long. I got 3 or 4 gallons out of my last set of Nova shoes. They could have gone maybe a little longer, but I happened to have the clutch apart and a new set of shoes in my box, so I changed them out.

I had nearly zero break in time on both sets of Nova's I've used. The Mugens took a while to break in.

I currently have 1.1mm springs on one of my Savages, and 1mm springs on the other. I much prefer the 1mm springs.

When installing aluminum clutch shoes, the Mugen pilot nut and an OFNA shim kit makes the job much easier. Trying to get everything to fit properly without them, takes quite a bit of creativity and Dremel work.

I'm going to get the nova engine mount at the same time as the werks clutch so I can move the engine back slightly.

I prefer to make my own clutch shoes since i make them out of 6082 T6 aluminium and they last longer than the STD alu shoes you buy. I'm sure there are really good ones out there but i cant get my hands on them and this way i save myself the hassle of replacing CB shoes every weekend.

takes 3 hours to make

I have the Werks Racing power clutch, my #1 preference. Expensive, and a little tricky to get fitted up. Pass on the Werks clutch if you are new to clutching. I also like the Mugen MBX4 carbon setup. The best value, as far as clutching, doesn't bite as hard as the Werks, but cheaper, and bolts right on to the stock Savage flywheel. You need Mugen MBX4 shoes, either 1.0, or 1.1 springs, and the Mugen MBX4 clutch nut. I don't run aluminum shoes, as they beat the poop out of std. Savage clutchbells, and especially Ofna shoes are extremely soft, which need frequent de-burring, and make a filthy mess internally on your clutch.

Did you have any problems fitting the Werks clutch on your engine?
