AF1 Racing Spring Rate Checking Service
Here at AF1 Racing, we're starting to see more and more spring rate variances on older bikes than we'd expect. To complicate matters further, many aftermarket fork springs and some rear shock springs are not marked at all.
If you have a front fork spring or rear shock spring that you'd like to know the precise spring rate on, please purchase this service, then send your spring (or springs) to:
AF1 Racing, Inc.
Attn: Spring Rate Check
9900 North Interstate 35

Turn around time is one day.
