GKTech Nissan 240sx/Silvia K-Frame/Tension rod mount weld in reinforcement kit - S14/S15

The GKTech K-Frame / Tension Rod Mount Weld-In Reinforcement Kit is designed to strengthen the front subframe (K-frame) in S14 and S15 Silvia chassis, specifically at the tension rod mounting points, which are prone to flexing and cracking under heavy loads. This is a critical area of the front suspension, and reinforcing it improves steering precision, braking stability, and overall chassis rigidity—especially under the demands of drifting, grip driving, or high-performance street use.

Laser-cut from high-tensile steel, these weld-in plates are shaped to fit the OEM K-frame perfectly, boxing in and reinforcing the tension rod pickup point for long-term durability and reliability.

Key Features:

• Reinforces Front Subframe: Strengthens tension rod mounts to prevent cracking and flex

• Improves Chassis Stability: Helps maintain consistent alignment and suspension geometry

• Laser-Cut Precision: Designed for an exact fit on S14/S15 K-frames

• Track-Tested Reliability: Built for aggressive driving and high-stress environments

Specifications:

• Material: High-tensile steel

• Install Type: Weld-in

• Install Time: ~2–3 hours (requires subframe removal and prep)

Compatibility:

• Nissan S14 Silvia / 240SX (RWD only)

• Nissan S15 Silvia (RWD only)
  Not compatible with S13 or AWD models.

What’s Included:

• (1) Pair of weld-in reinforcement plates (left and right)

• (1) Reference diagram for installation

Notes:

• Professional welding required – subframe must be removed for proper access and fitment

• Ideal when upgrading to adjustable tension rods or solid bushings

• Can be used alongside other GKTech chassis reinforcement products for maximum rigidity

Lock down the front end of your S14 or S15 with GKTech’s K-Frame Reinforcement Kit—engineered for strength where it counts and built to keep you in control.
