H&R Sway Bar Kit – BMW 335i & 335is (E90/E92/E93, N54/N55)

OVERVIEW

H&R's sway bar kit for the non-xDrive E9x 335i and 335is replaces the factory front and/or rear anti-roll bar with a larger-diameter tubular bar for increased torsional stiffness, reducing body roll and sharpening turn-in. Offered as a Front Only, Rear Only, or matched Front & Rear Set.

This kit is built for rear-wheel-drive E9x chassis only — the xDrive-equipped 335i xDrive uses a different H&R part number due to its different front subframe and steering geometry.

SPECS

• 27mm front bar / 20mm rear bar (per H&R and retailer spec sheets)
• Larger diameter than the factory bar for reduced body roll
• Includes H&R mounting bushings and hardware for the selected configuration
• Direct bolt-on to factory mounting points

PARTS INCLUDED

• Sway bar(s) for the selected configuration (Front Only, Rear Only, or Front & Rear Set)
• H&R mounting bushings and hardware
• Installation instructions

TECH RESOURCES

Additional Parts Required

• None. H&R includes the mounting bushings and hardware needed for installation with each configuration.
• A four-wheel alignment is recommended after installation (service, sold separately).

Installation

• H&R general technical & installation information (PDF, hosted on our Shopify) — H&R does not publish a sway-bar-specific install guide separate from this general technical document.

Notes

• Non-xDrive (RWD) fitment only. Confirm drivetrain before ordering — 335i xDrive requires a different H&R part.
• hrsprings.com's product catalog is JavaScript-only and could not be crawled directly; the part numbers below are confirmed against this SKU's own Shopify variant field and cross-checked against Turner Motorsport, ECS Tuning, and USP Motorsport listings for the same H&R parts.
