Product Details

The Weld Racing RT-S S77 is a classic tuning fork design reimagined for modern muscle. Built with 3-piece forged construction using cold-forged outer shells and a forged 6061 aluminum center, the S77 delivers the proven strength and reduced weight that Weld Racing is known for — purpose-built for street and strip performance.

This wheel features a medium-pad mounting design that provides clearance for a wide range of brake packages, making it a versatile choice for street driving, drag racing, road course, and autocross applications. The conical lug seat style and 3.180-inch center bore ensure precise fitment, while the matte black anodized finish gives it an aggressive, track-ready look.

Key Features:

  • 3-piece modular construction with forged 6061 aluminum center and cold-forged rim shells
  • 18-inch diameter × 10-inch width with 5×4.75-inch (5×120.65mm) bolt pattern
  • 4.7-inch backspace — medium pad height for broad brake caliper compatibility
  • Matte black anodized finish on center; black outer shells
  • Load rating: 1,580 lbs. per wheel
  • Lug nut seat: 60-degree conical — requires conical lug nuts
  • Non-beadlock design
  • Does not accept 5/8-inch wheel studs
  • Center cap and valve stem included
  • Made in Kansas City, MO, USA

The RT-S S77 is sold individually and is manufactured in the USA to Weld Racing's exacting quality standards, carrying on decades of motorsport heritage into a street-ready package.

First time shopper, Great

great store to deal with shipping is a little high but good at keeping me updated on my order

Damn fast on the shipping and great price on the item a great place to shop

Great pricing, free shipping, and great product!!! What we got was better than OE for 1/5 the price! Thank you!

super easy checkout with amazon link! Let's you know if in stock or not, which is critical when ordering racing components.

Excellent price, quick shipment, and recommended to anyone! They have the cheapest prices on the web! Period!

They have great prices! The same item I purchased from autoplicity is on summit racing for triple the price! This is my first order and I am very happy, will order from again!

I appreciated the Amazon pay option.

easy to find what i needed and best prices on the internet.

An excellent combination of a terrific price on the Thule product I ordered and very fast delivery. My only regret is that I had to order the fit kit more my car from another vendor.

Quick and easy to use website. The part doesn't fit my 2005 Malibu even though the website says it does - have to return the part.

Found the best price on my High Rock 4x4 Overhead Rack. They even discounted the shipping for me. Quick to ship and provide tracking info. Very happy with the way this company operates.

It took a day or two for them to ship my order, but it arrived quickly once shipped. The price was by far the best available.
