Race Tech Gold Valve and Fork Spring Kit For Harley-Davidson 39mm Fork

  • Fork caps available separately
  • Detailed instructions are included

The factory suspension is a compromise for many styles and built to a price point. If you want the classic looks of a 39mm narrowglide fork but want to pack some heat "under the hood," Race Tech Gold Valve and Spring kits from TC Bros. are the complete solution. Especially if you're rebuilding a fork with a set of our fork tubes, why not improve the internals?

Race Tech's cartridge emulator kits are the benchmark for keeping stock appearance but ratcheting up the performance. The heart of the kit is the spring; Race Tech offers several options to ensure you get the appropriate rate for your scenario and preferences.

The Gold Valves, known popularly as cartridge emulators, offer tunability that the factory suspension can't. Conventional damper rod forks offer primitive damping control that's not very dynamic; it's difficult to make this type of suspension perform well at both high and low cycling rates. Coupled with springs that are often inappropriate, it's no wonder that a stock 39mm fork leaves something to be desired performance-wise. Cartridge emulators are how you convert your damper rod setup behave like a modern upside-down suspension—the valving responds to the speed of the tubes during their stroke. 

Don't swap your fork. Make the narrowglide you have be all it can with internals from Race Tech!

Quality and Functional
Color: Navy Blue, Color: Navy Blue
I was looking for a case that could rotate and includes a keyboard. I have the gen 5 Ipad Air and it fits just fine. The part that rotates is magnetic (pretty strong) so if i just want the part with the ipad, I can just take it off. Keyboard is magnetic and the touchpad is such a bonus. It was easy to connect and every key works (can also change light color). Im also really impressed with the quality of the case, its pretty thick and even the plastic is nice. The navy blue color is also super cute, wish they had a dark red color too.

ABSOLUTELY PERFECT - I LOVE THIS!!!
Color: Pink
I absolutely LOVE this case and the keyboard - it’s absolutely perfect in just about every way. If I had to get nit-picky and find something to give feedback on, I would say it is a bit heavy and it is a bit annoying that you have to move the keyboard forward when you want to use it and backward when you want to close up the case but I don’t care, I love it!

Quality Case

This is an All in Pne case. I really like the lavender color with sparkles. It is a little heavier than expected but I still love it!

Ok, but don’t use hand cream
Color: Black, Color: Black
I like the case for its ability to house the keyboard, the pencil and the iPad in one convenient place. I find that the magnetic closure and magnets holding the keyboard are not as strong as a previous case I had purchased. The keyboard is great, I like the touchpad and the backlight colors. The cover material is not hand lotion friendly! I’ve tried water and lens cleaning wipes, and neither gets this cover clean. I hesitate to use any chemicals because the material is the type that will get sticky and nasty, and I don’t like that. I’ve included a photo of what the cover looks like after using a lens cleaning wipe. If the magnets were stronger and the cover material easier to clean, I would buy again.
