ICON Tubular UCA with Delta Joint PRO — 2024+ Tacoma / 4Runner / Land Cruiser / GX 550
The ICON Tubular Upper Control Arm Kit with Delta Joint PRO (58452DJ) gives you ICON's flagship articulation joint in a heavy-wall DOM tubular steel arm — the more accessible entry point into ICON's UCA lineup compared to their range-topping billet components. The result is a full suspension upgrade with the same Delta Joint PRO performance at a price that's more accessible for builds that don't need the additional camber/caster adjustability of the billet arm's Heim joint system.
Additional caster is built into the arm geometry — no shims needed to correct front-end alignment on a lifted Tacoma, 4Runner, Land Cruiser, or GX550. The Delta Joint PRO eliminates bind through the full range of travel, allowing performance coilovers to use their complete suspension stroke. The frame pivot bushings are Heavy Duty Dual Stage units in precision-machined housings — greaseable and rebuildable, and notably more responsive than the soft OEM rubber bushings they replace.
Tubular vs Billet — Which Should You Choose?
-
Tubular (this listing, 58452DJ) — $849.95 — Heavy-wall DOM steel, built-in caster correction, Delta Joint PRO, dual-stage bushings. Best choice if you want ICON's Delta Joint PRO and caster correction without the cost premium of the billet arm.
-
Billet (58552DJ/GDJ) — $1,399-1,479 — 6061 billet aluminum H-beam, FK Rod End Heim joints, on-vehicle double adjuster sleeve for camber and caster tuning, lighter weight. Best choice if you want maximum adjustability and the lightest possible arm.
If your build is primarily about correcting geometry and unlocking full travel with a quality ball joint, the tubular arm delivers. If you want the ability to fine-tune alignment on the vehicle as your suspension evolves, the billet arm's Heim joint system is worth the premium.

Delta Joint PRO
-
90° total articulation — 14% more than ICON's original Delta Joint; bind-free through the complete range
-
56% more bearing surface — improved load capacity and longevity
-
Fully rebuildable — any component replaced individually; anodized billet aluminum dust cap protects the grease fitting
-
Chromoly ball and shaft — bearing surface hardened to Rockwell C 55
-
Graphite-impregnated sintered metal races — metal-to-metal bearing interface, precision machined
DOM Tubular Construction
- Heavy-wall DOM (Drawn Over Mandrel) tubing — consistent wall thickness, clean internal surface, tighter tolerances than standard welded tube
- CNC formed and fixture welded — precise geometry, repeatable quality
- Multi-stage semi-gloss black powder coat finish

FAQ
What's the difference between this and the ICON Billet UCA (58552DJ)?
Both use the Delta Joint PRO. The tubular arm has built-in caster correction but fixed geometry — no on-vehicle adjustment. The billet arm adds FK Heim joints and a double adjuster sleeve for on-vehicle camber and caster tuning, plus lighter weight from the 6061 aluminum H-beam construction. The tubular is the better value; the billet is the more flexible option.
Does this have built-in caster correction?
Yes — additional caster is built into the arm geometry. You don't need shims or additional hardware to correct front-end alignment on a lifted vehicle.
Are the frame pivot bushings replaceable?
Yes — the Heavy Duty Dual Stage bushings are greaseable and rebuildable. ICON designed them to be serviceable in the precision-machined housings rather than requiring full arm replacement when bushings wear.
What is DOM tubing?
DOM (Drawn Over Mandrel) is a manufacturing process that produces tubing with consistent wall thickness and a clean internal bore. It has tighter tolerances and higher strength than standard electric-welded tube — important for structural suspension components where wall consistency affects strength predictability.
Do I need a wheel alignment after installation?
Yes — always required after any UCA swap.
