That's a different link. The original link shows this:

What thread size did you need for those bolts. I contacted Wilwood and they said nothing was needed to mount the caliper, but apparently a couple bolts need to be purchased?

I anti-seize or Loctite nearly every thread no matter the material since both exclude moisture. I've taken apart hardware I installed thirty years ago on bikes, trucks etc with zero problems. Electrical parts like starter cable studs get dielectric silicone grease.

Marine anti-seize with copper or high temp anti-seize with nickel are more expensive but a container lasts years.

Just about to hit the buy button on a single left caliper for 03 sporty.
Anyone know of issues with wire / non cast wheels (stock 883 Hugger) ?
Stock brake reservoir good to go ?
And why didnt anyone reuse the bolts from the caliper you removed ?

As far as I know, it should just bolt up fine. Cast or spoke, no difference at brake caliper.

Please report your installation and results. If you need to purchase additional hardware, please list it for size/thread/etc. The stock M/C should work just fine. I've got a Magnum Shielding brake line ready to go, just need to pull the trigger on the Wilwood caliper sometime.

Good luck, I look forward to your report.

It was a couple of years ago. I am still very satisfied with the upgrade. The stock caliper has outside dimensions that are a little different than the Wilwood caliper.

At least I think mine did. Just took a couple of depth measurements and made a trip to Lowes. Common sizes. Don't make the mistake I did originally and buy SS bolts. A member here picked it up in the first pic I posted. The sheer strength isn't adequate for this application. Buy grade 8

You go from 1 sliding pin 1 3/4 piston to 4 pistons the same size. I did use DOT 5 fluid since that's what the manual called for. I put on a new line and the new caliper so there was no worry about flushing the system.

I’m going to quote myself. Summit and or Jegs run sitewide discount sales frequently. I don’t know if that discount code is active. If not, just check the websites, there’s a new code and sitewide deal every week.

Currently with code FALL100 you get $20 off (and free shipping).

I saw that price earlier this summer, with similar sitewide discount, but then acquired the used Wildwood caliper.

Summit wants a lot more for the polished version. Jegs has the polished for around $221, but only $10 sitewide discount.


I would have just installed a used four piston Dyna caliper with a bracket I bought, but it rubbed on a wire spoked wheel.

If you have a 9/16 bore master cylinder (the size is cast into it, look at the outside underneath) you will be fine. I went from almost no free travel and a “hard” lever, to about 1/3 travel before it firms up with good braking feel and better braking action.

I’d recommend a stainless brake line with the swap.
