Archive’s Stealth HD U-bolt flip kit fits stock 60mm (2.375″) to 2.5″ wide springs max, bolts are kept tight to pack to prevent your leaves from rotating out of alignment.
This kit allows you to remove bumpstops without removing the U-bolts and U-bolt plates.
Option 3 is our best option, Archive Speed bumps are 100% designed by us for:
1) soft engagement
2) max bump travel
3) slowing weight down over more distance & progressive feel
4) no center hole in bump to fill up with water
5) two tough 3/8″ bolts to hold bumpstops down.
(note: yellow color fades to amber over time)
Note: For Option 2,4 & 5, spring center bolt threads must be trimmed to a max height of 1/2″ above the spring
