Heavy-Duty Steel Rear Leaf Spring 3300 lb – OEM 43-1261 (Truck / Trailer)

Overview

This rear leaf spring is a new aftermarket replacement available from Asia Parts Store. It is listed against OE reference 43-1261, so you can match it against the number on your existing part before ordering. It is aimed at owners of 4x4s, utes and light commercial vehicles who want to restore or adjust ride height and suspension support for New Zealand roads, tracks and work use.

Leaf springs carry the weight of the vehicle and its load on the rear axle of most utes and light commercial vehicles. Over time springs sag, crack or lose their arch, which lowers ride height, reduces load capacity and can cause the vehicle to bottom out. A replacement spring restores ride height and support.

Signs that leaf springs need replacing include a rear end that sits low or leans to one side, bottoming out over bumps, cracked or broken leaves, and leaves that have flattened out. Replacing worn springs restores ride height and helps the vehicle carry its load safely.

Fitment & Installation

Leaf springs are normally replaced in pairs so both sides sit at the same height. Fit new spring bushes and U-bolts where required, torque the U-bolts and spring eye bolts to specification with the vehicle at ride height, and have the axle alignment checked if the vehicle tracks unevenly.

Professional installation is recommended. In New Zealand, suspension and ride-height changes must still meet Warrant / Certificate of Fitness requirements, and larger modifications may need LVVTA certification — check with a certifier before fitting if you are unsure.

Before You Order

To make sure you receive the right part first time, send the Asia Parts Store team your vehicle's make, model, year, engine code and VIN or rego, along with the OE number from your existing part.
