Overview

The Per4Mance Development DIRS-R is a differential brace designed to reinforce your differential case and improve your car's IRS operation and traction. This two-piece system attaches to the differential using main case bolts and lower case bolts, while the second part connects to the rear cross-member, adding a third, triangulated integration point. It is constructed from American-made, CNC-machined T-6061 billet aluminum with a hard anodized black coating and includes ARP fasteners or equivalent.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
