Product Details

The Rubicon Express RE4521 Extreme Duty Crossmember is an essential upgrade component for Jeep Wrangler JK owners installing long arm suspension systems. This heavy-duty front crossmember replaces the factory single-piece unit with a significantly stronger 3-piece bolt-together design that provides the structural integrity needed for proper long arm suspension performance.

Key Features:

  • 3-piece bolt-together construction for exceptional rigidity and strength
  • Direct bolt-on replacement for factory front crossmember
  • Textured black powder coat finish for corrosion and rust resistance
  • Includes 4 oversized bump stops to prevent suspension-to-frame contact
  • Engineered specifically for long arm suspension systems
  • Compatible with Jeep's Electronic Stability Control and factory electronic sway bar systems
  • Backed by Rubicon Express lifetime transferable warranty

This crossmember significantly reinforces the mounting points where long control arms attach to the frame, providing proper leverage for alignment and ensuring optimal suspension geometry. The heavy-duty construction withstands the increased forces generated by long arm suspension systems during aggressive off-road use. Installation requires moderate mechanical skills, and all necessary hardware is included for bolt-on installation.

What's Included: Long arm suspension crossmember (3 pieces), mounting hardware, and 4 bump stops.

Autoplicity had the best price by far on the item I was looking for. I paid for 2nd day air shipping and my order total was still less expensive than ordering from any other merchant. My item arrived the day after I ordered it. I will definitely buy from them in the future.

Best price fast shipping. will deffinitly order again

Best Price on the Net for K&N System for my 2012 HEMI RAM. My Order 18270 is shipping today and I can't wait to get it installed!

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

Best price on the Internet and quick shipping

Very fast and easy ordering system. My order was shipped the next day.

easy to use site, quick and easy, cant wait to get item. Coupon was a huge plus

So far so good! Just ordered the parts I needed for my car which I've been trying to find EVERYWHERE without success, until I arrived at autoplicity. Great price, and with a lifetime warranty I'm assuming great quality. I have faith that when the product arrives I will be highly satisfied.
