Direct replacement for the OEM shock spring. Mounts on the existing Ultra Bee rear shock body — no shock replacement, no linkage modifications. Spring compressor required for installation; if you don't have one, we can install it for you in the shop. Select color at checkout.
The 500 lb shock spring is the middle ground between the OEM spring and the heavy-rider 550 lb rate. It's calibrated for riders in the 170-190 lb range riding with a normal-to-moderately-aggressive style. If you're in that weight range and feel like the stock spring is bottoming out on bigger hits or compressing too much in corners, this is the right step up.
Who this is for: most adult riders in the 170-190 lb range. Standard recreational riding, occasional jumps, varied terrain. If you're heavier than 190 lb or you ride very hard, jump regularly, or do drop-offs, look at the 550 lb version instead. If you're lighter than 170 lb and ride conservatively, the stock spring is probably fine for you.
The spring is made from 55SiCr alloy steel — a high-carbon spring steel commonly used in motorcycle suspension. Stronger than the stock alloy, more consistent rate across the spring's working range, and resistant to the sag that happens to OEM springs after a season of hard use. Available in Black or White anodized finish.
Installation requires a spring compressor and disassembly of the rear shock — it's an advanced job. If you don't have the tools or experience, we'd recommend having a shop install it (we offer this service if you're local). After installation, you'll need to reset your sag for the new spring rate — typically 30-35% of total travel.
