Peterbilt 375/377 Tilt, Trailer & Signal Handles

Frequently Asked Questions About Peterbilt 375/377 Tilt, Trailer & Signal Handles

What are tilt, trailer, and signal handles used for on a Peterbilt 375/377?

These handles are the interior control levers mounted on or near the steering column that operate the steering wheel tilt function, the trailer brake (hand valve), and the turn signal/multi-function switch. They are the parts your hand actually grips and moves inside the cab to control these systems, and they commonly wear out, crack, or break due to daily use.

Will these handles fit my specific Peterbilt 375 or 377 model year?

Fit can vary depending on the cab configuration, steering column style, and whether your truck has factory or aftermarket switch assemblies. Always check the listed year range and part number on each product page, and compare it to the handle currently installed on your truck before ordering. If you are unsure, having your VIN or the original part number on hand will help confirm compatibility.

Are these handles OEM parts or aftermarket replacements?

We carry both OEM and quality aftermarket options depending on the specific handle. OEM parts are built to match the original fit, finish, and feel of the factory component, while aftermarket handles are designed as a direct functional replacement, often at a lower cost. Each product listing will note whether the part is OEM or aftermarket so you can choose based on your preference and budget.

How difficult is it to install a replacement tilt, trailer, or signal handle?

Most of these handles are designed for straightforward replacement using basic hand tools, and many bolt or snap into place without needing to disassemble the entire steering column. That said, some signal handles may require disconnecting wiring harnesses or removing a steering column cover, so it helps to have a service manual or install guide on hand, especially if you are replacing a combined signal/multi-function switch.

What material and finish options are available for these handles?

These handles are typically made from durable plastic or chrome-plated components designed to withstand daily cab use. Chrome-finished handles are popular for both appearance and durability, while black plastic handles offer a factory-matched look. Check each listing for specific material and finish details, since options can vary between the tilt, trailer, and signal handle categories.
