Gear Review · Suspension
All 10 suspension upgrades we've tested and ranked, springs, valving, linkage, and hardware to dial in your bike, sorted by rating. Prefer a full sag check first? Try our sag setup tool.
Fork and shock springs, valving kits, linkage, and hardware, most suspension parts are bike- and weight-specific, so confirm application before you buy.
Suspension
Drops into most conventional forks to replace basic shim-stack damping with genuine compression valving, the single most proven way to transform a harsh, underdamped stock fork without a full cartridge swap.
Suspension
Weight-matched fork springs are the highest-value first upgrade in suspension, full stop, stock springs are a compromise rate for an "average" rider, and most riders aren't average. Held to tighter rate tolerances than OEM.
Suspension
The rear-end companion to Race Tech's fork springs, pairs your bike's shock to your actual weight and riding style instead of the factory's one-size compromise. Use our sag calculator first to confirm you need a rate change before buying.
Suspension
Changes the rear linkage ratio to drop seat height without cutting into travel as aggressively as a spacer-based drop, genuinely useful for shorter riders who've felt unstable flat-footing a stock-height bike.
Suspension
A revised leverage-ratio linkage built from Pro Circuit's own race program, reshapes how progressive the rear end feels through the stroke rather than just changing ride height.
Suspension
Aerospace-grade titanium with rolled threads, roughly 45% lighter than the stock steel bolts they replace, a small, affordable swap for riders chasing unsprung weight savings at the swingarm.
Suspension
Worn wheel bearings show up as vague, notchy steering and premature tire wear long before most riders think to check them, this kit covers bearings, seals, and collars in one box instead of piecing it together.
Suspension
Air pressure builds in your forks as you ride and, left unreleased, makes them feel harsh over small bumps, these tool-free bleeders vent it with a single press instead of digging out a screwdriver trackside.
Suspension
Leaking fork seals are one of the most common suspension complaints, and usually the cheapest to fix, this kit covers both the oil seal and dust wiper so you're not ordering twice when one wears out.
Suspension
The one truly universal product on this list, sold by viscosity, not application, so it fits any bike. Fresh fork oil on schedule is the cheapest, most overlooked suspension "upgrade" there is.
