I have noticed a lot of you guys using the Girvin forks for rat builds. They look cool, almost like a triple clamp, have the large coil inside them if you are fortunate enough to get one of the newer ones without the elastomer bumper.

I went with the other 90s linkage fork, AMP Research. I first installed an AMP on my '56 columbia about 15yrs ago, called it modern springer technology. Now it resides on my Kona:

I think that is a F2 or F3 fork, not 100%, they did make another afterwards that had dual coil-over dampers on each side of the linkage that i think was the F4. I recently acquired two more. They are the earlier design using cromo lowers. The design is quite flimsy for off road use and i hear they tend to break if abused. One is mostly a parts fork, the other is near new! They have different steerer diameters, 1" and 1-1/8", so i want to keep both around in case i want to swap the steerer between the two. Not sure what to put the vood one on, i did see a sweet 90s Retrotec at Veloswap this year i wish i had the funds for. Anyways, here are the older ones

My question is if anyone here has utilized these forks in the past as i have for a rat rod, or if they have just been tossed aside for safety concerns or do people just prefer the look of the Girvin? Some of the older cruiser frames seem to get dwarfed by such a large fork, the AMP is a little less overwhelming in my opinion. Let me know what you think, and if you know of any builds that ran this fork could you please link it bere for me :) gotta get to work overhauling a vintage schwinn sidewinder or i could spend time searching myself!

That fork I used to run on a few MTB frames years ago. They are really a cool linkage design with a side-mounted oil damper, which typically had some failures such as air and oil leaks. I had no other problems with the ones I ran years ago. They are a bit more complicated of a design than the Girvin, but IMO better looking. I had no issues running them hard on my MTB's, and they were not flimsy or floppy in any way. FordSnake used one on his Salt Flats bike a few years ago. They swing up and backwards when compressed. Great forks for sure! 1" steerers as well..

I was going to use one on SaltHammer with a FloCycle, but it wouldn't fit right.
@fordsnake had one on one of his BO bikes a few years back.
The AMP forks remind me of the Shelby ShockEase forks alot.
