Eibach 35140.31 27mm Front Anti-Roll Kit for 13-19 Focus ST

Vehicle Fitment

• 2013-2019 Ford Focus ST (2.0L Turbo I4)

Fitment Notes

• Front sway bar only - not the rear bar and not a full front+rear kit
• Worth flagging directly: this "35140" part number prefix is shared across several different Eibach products for the Focus ST platform - 35140.140 is the Pro-Kit lowering springs, 35140.310 (this part) is the front anti-roll bar, 35140.312 is the rear anti-roll bar, and 35140.320 is the combined front-and-rear anti-roll kit. Confirm the full suffix carefully before ordering, since these are not interchangeable parts despite the similar numbering.

Product Description

The Eibach 35140.31 is a 27mm front anti-roll bar built specifically for the Focus ST, aimed at reducing body roll and sharpening turn-in without touching ride height or spring rate on its own. It's a handling-focused upgrade rather than a stance upgrade - pair it with Eibach's Pro-Kit springs (35140.140) if lowering the car is also part of the plan, since this bar alone won't change ride height.

By stiffening resistance to body roll specifically (rather than stiffening the springs themselves), an anti-roll bar like this reduces the load transfer between inside and outside wheels through a corner without sacrificing ride comfort when both wheels move together over bumps - that's the functional difference between an anti-roll bar upgrade and a spring upgrade.

Given how many similarly-numbered Eibach parts exist for this exact platform, the most important thing before ordering is confirming you're getting the front bar specifically and not the rear bar, the springs, or the combined kit - all of which share the same "35140" prefix but are different products with different part suffixes.
