Kenworth T660 Shock Absorbers

Frequently Asked Questions About Kenworth T660 Shock Absorbers

Will these shock absorbers fit my Kenworth T660 without modification?

Shock absorbers in this category are designed to match the T660's factory mounting points and specifications, but fitment can vary depending on axle position (front or rear), ride height, and whether your truck has any suspension modifications. Always check the listed specifications, including length and mounting bushing size, against your truck's original equipment before ordering.

How do I know when my shock absorbers need to be replaced?

Common signs of worn shocks include excessive bouncing, uneven tire wear, a rougher ride than usual, visible oil leaking from the shock body, or a cab that continues to sway after hitting a bump. If you notice any of these symptoms, it is a good idea to have your shocks inspected and replaced if needed.

What is the difference between OEM and aftermarket shock absorbers for the T660?

OEM shock absorbers are built to match Kenworth's original specifications and are a safe choice if you want to replicate factory ride quality. Aftermarket shocks often offer a similar fit at a lower price point, and some are designed to improve durability or handling. The right choice depends on your budget, driving conditions, and personal preference for ride feel.

Can I install shock absorbers myself, or should I have a professional do it?

Replacing shock absorbers is a straightforward job for anyone comfortable with basic mechanical work and the right tools, including a torque wrench to properly secure mounting bolts. That said, if you are not experienced with suspension work or do not have access to a lift, having a qualified technician handle the installation ensures everything is torqued correctly and safely.

Should I replace shock absorbers one at a time or in pairs?

It is generally recommended to replace shocks in pairs (both front or both rear) at the same time, even if only one appears worn. This helps maintain even handling and ride quality on both sides of the truck, since shocks tend to wear at a similar rate once they have been in service for a while.
