Torsion Bar Set - '90-'97 Isuzu Pickup (2WD) & Trooper (4WD)
SKU 1566
Category: Isuzu Torsion Bars
The heavy-duty front suspension upgrade for the classic Isuzu Pickup and Trooper. These solid 25mm torsion bars are engineered to replace the lighter factory units, providing a 20–30% increase in spring rate. This added stiffness is essential for vehicles equipped with heavy steel bumpers, winches, or oversized tires, as it eliminates "nose-dive" during braking and prevents the suspension from bottoming out on technical trails.
Performance & Fitment
Application: Front Torsion Bar Set Diameter: 25mm (Heavy-Duty Upgrade) Spring Rate: +20% to +30% over OEM
Isuzu Pickup (TF) 2WD: 1990 through 1997
Isuzu Trooper (UBS): 1990 through 1991 (Square body)
Note: Fits models utilizing independent front suspension (IFS). Always verify your bar length before ordering, as Isuzu utilized several different lengths across 2WD and 4WD configurations.
Premium Construction
Material: Solid 4340 aircraft-grade alloy steel, chosen for its exceptional fatigue resistance and "torsional memory."
Manufacturing: Centerless ground to a precise 25mm diameter to ensure a perfectly linear spring rate and remove surface micro-imperfections.
Heat Treatment: Through-hardened and shot-peened to maintain ride height and prevent the suspension from "settling" even under heavy loads.
Finish: Industrial-grade powder coating for superior protection against road salt and moisture.
⚠️ Critical Fitment Exceptions
Even if your vehicle falls into the year ranges above, you must ensure it does not fall under these exceptions:
❌ 4WD Pickup Models: This SKU is typically length-tuned for the 2WD Pickup geometry. 4WD models often utilize a different bar length (such as 39.31"). Measure your bar end-to-end to confirm.
❌ Pre-1990 Troopers: While the body style is similar, 1989 and older Troopers often used a different diameter or length bar. This 25mm upgrade is specifically valved for the late-model square bodies.
❌ Second-Generation Troopers: Will not fit 1992+ Troopers (UBS25/69), as they moved to a significantly longer and thicker torsion bar design.
