CR 7075 Blue EHD Aluminum A-Arms – Slash, Rustler, Stampede, XO-1 & More

Cobra Racing EHD Blue 7075-T6 Aluminum A-Arms – See FULL compatibility list below!

If you’re sending your Slash, Rustler, or Stampede hard and want elite durability, zero flex, and flawless handling, it’s time to upgrade to Cobra Racing’s EHD (Extreme Heavy Duty) 7075-T6 Aluminum A-Arms. These arms are built to survive brutal bashing, high-speed hits, and everything today’s BL-2s and VXL systems can dish out.

This is a front + rear complete EHD arm set, CNC-machined from true aircraft-grade 7075-T6 aluminum, finished in a navy blue anodized surface with chrome highlights for a tough, aggressive look. Stronger, straighter, and far more rigid than composite arms, these A-arms transform the way your truck handles — both off-road and on pavement.

These A-Arms are part of our expanding line of Traxxas Extreme Heavy Duty (EHD) parts, designed to maximize durability, performance, and handling for your 1/10 & 1/8 RC truck.  Now also available in Black and Red.
