Product Description

The SPL Parts SPL TR G8X Front Tension Rod Kit is engineered to maximize front suspension geometry and steering precision for the 2021-2026 BMW G8X M3 and M4. By replacing the factory rubber-bushed tension rods with precision PTFE-lined FK spherical bearings, the kit eliminates bushing deflection and delivers more direct steering feedback, improved braking stability, and enhanced front-end response.

The lightweight CNC-machined aluminum turnbuckles provide a wide range of caster adjustment while allowing easy on-car alignment changes. Stainless steel spacers also enable anti-dive geometry tuning for optimized suspension performance on both street and track. Manufactured in the USA using premium motorsport-grade materials, the SPL TR G8X kit is designed specifically for rear-wheel-drive G80, G82, and G83 chassis and is not compatible with xDrive models.
