Product Details

The Weld Racing RT-S S71 is a purpose-built forged aluminum wheel that brings proven racing technology to the street and strip. Part number 71LB8100B77A is an 18x10.0-inch wheel finished with a black anodized center, featuring a 5x4.75-inch (5x120.65mm) bolt pattern, 7.7-inch backspace, and approximately +56mm offset — ideal for applications demanding an aggressive rear stance with deep-dish clearance.

Key Features:

  • 3-Piece Welded Construction: Forged billet center and cold forged rim shells are assembled via a unique welded process, delivering a superior strength-to-weight ratio over cast alternatives
  • Low Pad Design: The low mounting pad height is engineered to clear drum brakes, early disc brake systems, and dedicated aftermarket drag racing brake packages
  • Black Anodized Center: Durable anodized finish resists corrosion and maintains a clean, race-proven aesthetic
  • Forged Aluminum Construction: Manufactured from primary forging-grade aluminum alloys for maximum strength and durability under demanding conditions
  • FEA & Destructive Tested: Each wheel is validated through Finite Element Analysis and in-house destructive testing to meet and exceed SAE J2530 aftermarket wheel standards
  • Wide Size Range Available: The S71 line spans wheel widths from 4.5 to 18 inches and diameters of 15, 17, 18, and 20 inches
  • Conical Lug Nuts Required: This 18-inch diameter wheel requires conical (tapered) seat lug nuts (not included)
  • Center Cap & Valve Stem Included
  • Made in the USA: Manufactured in Kansas City, MO

Specifications:

  • Diameter: 18 in.
  • Width: 10.0 in.
  • Bolt Pattern: 5x4.75 in. (5x120.65mm)
  • Backspace: 7.7 in.
  • Offset: +56mm
  • Pad Height: Low
  • Finish: Black Anodized Center
  • Construction: 3-Piece Welded Forged Aluminum
  • Beadlock: Non-Beadlock

The Weld Racing RT-S S71 is the go-to choice for performance enthusiasts who demand race-proven engineering on the street, drag strip, road course, or autocross. Valve stem and center cap are included.

fast easy

Fast shipping cheapest I could find, easy to deal with, great product

Prices are great on this site. The layout and checkout process are easy to use; Google checkout is definitely a plus. Shipping could be a little faster, especially if they had drop ships from their supplies for items not currently in stock. Overall good service and no problems.
