KONI Classic Rear Shock Absorber (pair) – Holden HQ / HJ / HX / HZ / WB Commercials (Part # 80-2320)

Eliminate rear-end bounce and axle tramp in your classic Holden commercial with the KONI Classic series. Engineered specifically for the leaf-sprung rear ends of HQ through WB Utes, Panel Vans, and One Tonners, the 80-2320 delivers tunable hydraulic rebound control to stabilize heavy payloads and performance street builds alike.

Product Overview: Leaf-sprung commercial rear ends are notorious for harsh rebound, unladen axle chatter, and excessive bounce over uneven roads. The KONI Classic 80-2320 rear shock absorber is custom-valved to bring modern suspension manners to full-size Holden commercials, ensuring the rear axle stays firmly planted whether running unladen or under load.

Finished in traditional KONI gloss red with the authentic Classic wing logo, it retains a period-correct undercarriage appearance. Featuring off-vehicle adjustable rebound damping, you can precisely dial in firmness to match factory leaf packs, reset lowered leaves, or upgraded helper springs. Built with heavy-duty chrome-plated piston rods and a fully rebuildable internal design, it offers exceptional durability and serviceability.

Key Features:

• Adjustable Rebound Damping: Off-car adjustability allows you to calibrate rebound rates to suit standard leaf springs, lowered leaves, or heavy cargo payloads.

• Tamed Leaf-Spring Dynamics: Drastically reduces axle tramp, hop under acceleration, and the floaty, uncontrolled rebound common in commercial leaf springs.

• Period-Correct Styling: Signature KONI gloss red finish delivers an authentic, era-appropriate appearance for detailed underbodies.

• Heavy-Duty Construction: Features hardened chrome-plated shafts and robust sealing designed to handle commercial chassis loads and street punishment.

• Fully Rebuildable Architecture: Serviceable and re-valvable design ensures these dampers can be refreshed or re-tuned for future suspension changes.

• Direct Factory Fitment: Bolts straight into factory upper and lower leaf-spring shock mounting locations with no modification needed.
