Detailed Description

The Rancho RS66102B-2 suspension kit is engineered for Jeep Wrangler owners who need a suspension upgrade that preserves steering integrity and geometry while adding room for larger tires. On listed Jeep Wrangler and Wrangler JK applications, Rancho uses application-specific components such as a forged pitman arm where needed, heavy-duty tubular front links where needed, and a fully boxed one-piece welded subframe where needed. The RS66102B-2 is also designed to work with stock wheels on most systems, making it a practical choice for trail use, work use, or daily driving.

This part number is box 2 of 2 and must be used with RS66102B-1. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
