What RockJock does
RockJock 4x4, legally Rock Jock 4X4 and DBA RockJock 4x4 by John Currie, is a privately held, family-owned manufacturer and direct-to-consumer retailer of specialized off-road vehicle suspension and steering components headquartered in Corona, California. Founded by John Currie with the introduction of the Johnny Joint rod end in 1996, the company designs and markets a portfolio of branded product lines — Antirock sway bars, Currectlync steering systems, Johnny Joint rod ends, RockNuts, and integrated Suspension Kits — plus towing solutions, body panels, and a deep Parts Department of replacement hardware. Components are engineered from 4340 chromoly, forged 4140 steel, and DOM steel tube, with greasable/rebuildable articulating joints that deliver 30-40+ degrees of articulation. Products are engineered to fit Jeep platforms from 1976 through 2026 (CJ, YJ, TJ, LJ, JK, JL, JT, XJ, MJ, ZJ) as well as the 2021-Up Ford Bronco.
The company's go-to-market is dual-channel: a NetSuite-powered direct e-commerce storefront at rockjock4x4.com and a nationwide U.S. authorized dealer network surfaced through a Dealer Locator. Pricing is unit-based with quantity discounts, ranging from $2 hardware items up to ~$1,450 premium billet-aluminum kits, with complete kit systems typically priced $625-$1,595. Two customer segments are served: off-road enthusiasts and Jeep/Bronco owners (primary) who self-install, and professional custom builders/fabricators (secondary) who use universal weld-in kits and component hardware for bespoke chassis. Revenue is generated exclusively through hardware sales, with a mix of one-time kit purchases and recurring replacement-part revenue from the rebuildable Johnny Joint ecosystem.
RockJock is privately held with no disclosed institutional investors, funding rounds, or M&A activity; the firm operates at 11-50 employees with U.S.-only geographic reach. The company maintains CCPA and California Proposition 65 compliance posture and supports customers with an instruction manual library, a RockTalk newsletter, and organic social media. Sub-brands include the John Currie Performance Group (JCPG), which offers premium-tier versions of core products.
