DescriptionThe whole story

Rooted in circuit-bred engineering, the Spider Racing fork preload lock for 14 mm hex adjusters brings race-division rigour to your suspension set-up. Machined from high-grade aluminium with the precise tolerances Spider Racing are known for, this set of two locks is designed to hold your fork preload setting exactly where you put it — lap after lap, without drift.

Key Features

  • Universal fitment for all fork systems using a 14 mm hex preload adjuster
  • Prevents unintended preload movement under the sustained shock-loads of track use
  • CNC-machined from premium aluminium for an excellent strength-to-weight ratio and long service life
  • Developed specifically for professional motorsport applications — race-proven design
  • Fast, tool-free installation allows quick fitment during paddock set-up
  • Supplied as a pair — one lock per fork leg

Design, Finish and Heritage

Spider Racing have built their reputation supplying suspension accessories to racers who demand components that look as purposeful as they perform. The fork preload lock 14mm Hex (part number 90.72) carries that same design philosophy: clean CNC geometry, a refined aluminium finish, and compact proportions that sit flush and unobtrusive against the fork top cap. There is no unnecessary bulk, no raw edges — just the kind of considered detail work that earns trust in the pit lane and translates directly to confidence on circuit.

Performance on Track

Fork preload drift is a subtle but consequential problem. As vibration accumulates through a race stint, an unlocked adjuster can creep away from its set position, altering geometry, chassis balance and corner-entry feel in ways that are difficult to diagnose trackside. The Spider Racing preload lock eliminates this variable entirely, clamping the 14 mm hex adjuster securely so that the suspension tune agreed on the data stack remains intact from the first apex to the chequered flag.
