Speed Merchant SM39A-1 39 mm Fork Preload Adjusters, Black Anodized
Regular price $169.95 USD
Category:
Fine-tune your motorcycle’s front suspension with Speed Merchant SM39A-1 39 mm Fork Preload Adjusters. Designed as direct replacements for stock fork caps, these adjusters make it easier to set front-end preload without removing the original caps or cutting spacers. A simple turn of the adjuster lets you increase or decrease preload for a more controlled suspension setup.
Each adjuster provides nearly 1 inch of preload adjustment, giving riders practical control over front suspension response and ride feel. The CNC-machined 6061 aluminum construction offers a strong, lightweight solution, while the black anodized finish provides a clean, durable appearance suited to custom and performance motorcycle applications.
Speed Merchant includes the required O-rings, and the adjusters arrive ready to install. This kit is made in the U.S.A. and is designed for compatible 39 mm fork applications. Verify fork compatibility before installation to ensure proper fit and operation.
