GKTech Front Drop Knuckles for Nissan Silvia S15

GKTech Front Drop Knuckles for Nissan Silvia S15 Specifications

The GKTech S-Chassis Front Drop Knuckles are engineered to restore and optimize suspension geometry on lowered Nissan S13, S14, and S15 platforms, delivering improved steering feel, stability, and front-end grip for both drift and circuit use. Manufactured from lightweight 4130 chromoly steel and developed using CAD design, CMM measurements, and FEA testing, these knuckles are available in three dedicated versions: Grip, Drift/Grip, and Pro Drift. Each variant is tailored to a specific driving style, offering optimized roll center and bump steer correction while maintaining precise and predictable steering response.

The Grip version focuses on time attack and circuit performance with OEM steering geometry retained, while the Drift/Grip version combines improved drivability with up to 60 degrees of steering angle for versatile street and track use. The Pro Drift version is aimed at competitive drifting, featuring up to 70 degrees of steering lock, adjustable ackermann, and added caster trail for maximum front-end control. Across the range, the lightweight construction reduces unsprung mass while the corrosion-resistant E-coating ensures long-term durability in demanding motorsport environments.

NOTE

• Being that the Pro knuckles have inbuilt caster trail it is recommended to pair these with adjustable strut tops for best results and for an adequate amount of adjustment
• All the listed knuckles are best suited to be used with the adjustable lower control arms
• Some coilover manufacturers have a larger clevis that may interfere with the knuckle edge, if there is adequate room this clevis edge can be trimmed back to suit.
