Bolaxin LT890 Heavy Truck Brake Spring Tool — Adjustable Steel Installer for Drum- Brake Return Springs, One-Hand Operation

The Bolaxin LT890 is a heavy-duty, adjustable truck brake spring tool designed to install and remove drum-brake return springs quickly, safely, and with one-handed operation.

Built as a direct replacement for LT890, LTI890 and 890 style units, this steel brake spring installer simplifies work on large commercial and heavy-duty truck drum brakes. The tool’s slotted tip and three-position adjustable holes keep springs at the correct angle and tension, reducing finger strain and wasted time while resisting rust and wear thanks to its durable steel construction.

How does the LT890 make brake spring installation faster and safer?

The LT890's slotted end captures the return spring securely and maintains the proper working angle so you don’t struggle with alignment. One-handed operation frees your other hand to support components or hold the drum, cutting installation time and minimizing pinch risk.

• Slotted tip preserves spring orientation for accurate placement
• Three adjustable hole positions let you control leverage and reach
• Single-hand use reduces need for secondary tools or helpers

What truck brake systems is this tool compatible with?

This tool is intended for heavy truck and commercial vehicle drum brake return springs and matches common LT890/LTI890/890 replacement part specifications. It works especially well on larger springs found in rear axles and air-brake drum assemblies.

• Fits standard LT890/LTI890/890 replacement part geometries
• Designed for large-diameter truck drum brake springs
• Useful for fleet, service-shop, and roadside maintenance

What features improve durability and long-term use?

The LT890 is forged from quality steel and finished to resist rust and corrosion, ensuring the tool remains reliable in shop and field conditions. Simple construction and a compact profile mean fewer failure points and easier cleaning after heavy use.

• High-quality steel resists bending under load
• Corrosion-resistant surface for longer service life
• Sturdy build tolerates repeated shop and roadside use

How do I use the adjustable holes and slotted end effectively?

Select one of the three hole positions to set leverage that matches spring tension and working space. Place the spring in the slotted tip, pivot the tool to stretch the spring into the mounting anchor, and release carefully while holding alignment.

• Choose hole position for desired reach and force
• Move dust cover away before beginning to avoid obstruction
• Keep tool tip engaged until spring hook seats fully
