Our catalog entry for this one is thin - it only turns up once, tied to 1974. Beyond that we don't have more detail on it, so we can't speak to spring rate, length, or which specific models it was fitted to.
If you're trying to match a rear shock for a 1974-era bike, give us a call with what's currently on the bike and we'll confirm fitment before you order.
