Lisle 59560 Stretch Belt Tool for GM

The Lisle 59560 Stretch Belt Tool is a heat-treated, double-sided steel installer designed to position stretch-type serpentine belts on specific GM 5.3L, 6.2L, and 6.6L gas engine pulleys quickly and reliably.

If you work on late-model GM trucks and SUVs, installing stretch belts can be fiddly without the correct tool. The Lisle 59560 removes guesswork by providing two tab lengths for different pulley locations—one for A/C pulleys on 2014-plus models and a shorter tab for main drive pulleys on 2019-plus models. Built from heat-treated steel with a black oxide finish, it resists wear and maintains the geometry needed to seat modern stretch belts without bending or slipping.

How does this tool make installing stretch belts on GM engines easier?

The Lisle 59560 gives you a dedicated edge to stretch and hold the belt over the pulley while you align other components, removing the need for improvised prying tools that can damage the belt or pulley. Its dual-tab design adapts to the common pulley positions on specified GM engine years so you don't need multiple specialty tools.

• Double-sided design covers both A/C and main drive pulley locations
• Long tab fits A/C belt routing on 2014 and newer GM trucks
• Short tab suited for main drive belts on 2019 and newer GM vehicles
• Solid hold reduces slippage while seating stretch-type belts

What engines and vehicle years is the Lisle 59560 compatible with?

This tool is engineered for GM V8 gas engines including the 5.3L, 6.2L, and 6.6L families where stretch-type serpentine belts are used. The two tab lengths match the most common pulley positions introduced across recent GM truck and SUV model years, reducing fitment surprises in the shop.

• Compatible with GM 5.3L, 6.2L, and 6.6L gas engines
• Long tab for A/C pulleys on 2014 and newer GM trucks
• Short tab for main drive pulleys on 2019 and newer GM vehicles

What materials and finish are used, and why does that matter?

The Lisle 59560 is made from heat-treated steel to provide rigidity and resist bending when applying force to stretch belts. A black oxide finish helps protect the surface from corrosion while reducing glare and scuffing that can transfer to belt fabric during installation.

• Heat-treated steel for strength under load
• Black oxide finish for corrosion resistance and reduced marking
• Durable construction for repeated shop use

Will this tool work alongside other belt installation tools in my set?

The Lisle 59560 is meant to complement a mechanic’s existing toolset rather than replace generic belt tools. Because it targets stretch-type serpentine belts on specified GM engines, it’s especially useful when paired with tensioner tools and pulley holding devices during full front-end service.

• Designed to work with common tensioner and pulley tools
• Reduces the need to improvise with screwdrivers or pry bars
• Slim profile fits tight engine bays where leverage space is limited

Who this is for: The Lisle 59560 Stretch Belt Tool is aimed at professional mechanics, independent shops, and DIY technicians who service late-model GM trucks and SUVs with 5.3L, 6.2L, or 6.6L gas engines. If you regularly replace or route stretch-type serpentine belts on 2014 and newer GM A/C pulleys or 2019 and newer main drive pulleys, this compact, dual-tab tool streamlines installation and protects belt materials during seating.
