Description
Product Overview
TORCH Off Road presents a premium square U‑bolt kit designed for demanding automotive applications. Each bolt is forged from high‑grade alloy steel (Class 10.9) and finished with a zinc coating to resist rust and corrosion. The 9/16‑inch thread size and 2.5‑inch width provide a strong, stable connection for axle and suspension components. The kit includes four bolts, measured 12.5 inches from inside the bend, ensuring ample coverage for most replacement scenarios.

FAQ
What vehicles are compatible with these U‑bolts?
The bolts fit most off‑road trucks, SUVs, and performance vehicles that use a 9/16‑inch thread and require a 2.5‑inch wide U‑bolt. Always measure your existing bolts to confirm fit.
Do I need special tools to install the square U‑bolts?
A standard socket or wrench that matches the square head size is sufficient. Ensure the bolt is fully seated before tightening to achieve optimal torque.
How does the zinc coating affect durability?
Zinc provides a protective barrier against moisture and road salts, significantly extending the bolt’s lifespan compared to untreated steel.
Is there a warranty on these bolts?
Yes, TORCH Off Road offers a lifetime warranty covering material and workmanship defects, backed by responsive customer support.
Can I use these bolts for non‑automotive projects?
While engineered for automotive axle use, the high strength and corrosion resistance make them suitable for heavy‑duty industrial or marine applications where similar specifications are required.
