The stock Genuine BMW front "upper" control arms (31126855741 & 31126855742) are great for standard daily driving and occasional spirited driving, but they tend to fall flat on the track due to the soft hydrobearing bushings causing excess deflection, creating undesirable handling characteristics.

In order to address this issue, Turner now offers new Performance Front Tension Rods with upgraded FK Spherical Bearings! These tension rods offer multiple benefits over stock control arms, helping to keep your BMW under control and on the track.

The biggest upgrade over the stock control arm is the replacement of the rubber bushing with JMX hardened Teflon-lined low-friction FK Spherical Bearings. This allows for smooth control arm articulation, without the standard mushy feel you'd expect from rubber bushings. As a result, you get a more responsive feel that inspires confidence lap after lap! The PTFE liner is chemically bonded to the inner diameter of the race. The liner offers a very high load carrying capacity and has greatly increased dynamic wear characteristics, offering robust reliability for both street and track use.

Another benefit of these Performance Tension Rods is increased caster adjustment, allowing precise alignment for optimal turn-in response and to compensate for variances between left and right caster.

Adjustable Tension Rod Features:

• Gun drilled and Blue Anodized 2024 Aluminum links to reduce unsprung weight
• Rotating 6061-T6 Aluminum Clamp design
• Hardened JMX high misalignment low friction 3-piece Teflon lined FK Heim joints/rod ends
• Stainless steel anti-dive spacers
• ASTM A574 socket head cap bolts are used for maximum articulation with a minimum tensile strength of 170,000 psi
• Sold as a pair.
• Made in the USA.
