About this item
The complete FASTACE suspension kit pairs our front fork and rear shock — both pre-tuned to your weight and riding style — for a single bike platform. Kit pricing is meaningfully better than buying the components separately.
Both components ship with matched damping curves so the front and rear behave consistently under braking, acceleration and impact. This is the package most of our race-team customers run.
Features
- FASTACE front fork + rear shock, matched damping curves
- Both pre-tuned to your weight, gear and primary terrain
- Direct-fit hardware included (no adapters needed)
- Set-up sheet with rebound, compression and sag baselines for your bike
- Free email tech support for the life of the product

Setup & install
Most installs take 40–60 minutes with standard moto shop tools. Full instructions ship with the product.
Install the front fork following the fork install procedure.
Install the rear shock following the shock install procedure.
Set front sag (25–30 mm) and rear sag (30–40 mm) with rider in full gear.
Apply the supplied baseline rebound and compression settings; ride 30 minutes on a familiar trail.
Adjust one click at a time per ride session — never change more than one variable at once.
Maintenance
- Service both components on the same interval to keep damping curves matched.
- Always re-check sag after a fork or shock service.
- Email support@fastace.bike with photos / video of any rebound or compression changes you can't dial in.
Frequently asked questions
Q01Why buy the kit instead of separate components?
Two reasons: kit pricing saves you a meaningful amount versus buying separately, and our factory matches the damping curves of the fork and shock as a pair.
Q02Can I install it myself?
Yes, if you've replaced a fork or shock before. Otherwise, any moto shop with basic suspension experience can install in under 2 hours.
Q03Do I get a setup sheet with the kit?
Yes — we include a printed sheet with rebound, low/high-speed compression and sag baselines for your specific bike model and weight class.
Q04Is the kit warranty different from individual components?
No — both the fork and the shock are covered by the same 24-month warranty as if you'd bought them separately.
