Panhard-Trac Bars
Shop Pan hard trac bars, bushings, and related rear suspension components for classic cars and trucks. Find adjustable configurations for Chevy and GMC trucks, Impalas, Bel Airs, Biscaynes, and other compatible applications.
Panhard Track Bars and Rear Axle Position
Lowering a vehicle can expose something easy to overlook: the rear axle doesn't always stay perfectly centered as suspension geometry changes. The Panhard bar controls that side-to-side position, which is why adjustable versions become especially useful on lowered and air ride builds.
That role is particularly relevant to 1960-72 Chevy and GMC trucks, where the collection includes standard and Deluxe adjustable designs for C10, C20, Suburban, and 2WD Blazer applications. The Deluxe C10 setup relocates the mounting arrangement between the frame and trailing arm, creating a different solution for modified rear suspensions.
Full-size Chevy applications follow their own path, with adjustable bars and rear suspension packages for Impala, Bel Air, and Biscayne models across several year ranges.
Polyurethane bushing kits complete the collection by addressing wear and deflection at the mounting points, covering classic Chevy/GMC trucks, Impala, and Camaro/Firebird applications.
FAQ
What does a Panhard bar do?
A Panhard bar helps locate a solid rear axle laterally under the vehicle. It connects the axle or suspension assembly to the chassis and controls unwanted side-to-side movement while allowing the suspension to move vertically. It is also commonly called a trac bar or track bar.
Why would I need an adjustable Panhard bar?
An adjustable bar allows its effective length to be changed so the rear axle can be positioned correctly for the vehicle's suspension setup. This can be particularly useful after lowering. POL's 1960-62 and 1963-72 Chevy/GMC truck adjustable bars are specifically designed to help center the rear end and work with lowered applications.
Are Panhard bars available for lowered Chevy C10 trucks?
Yes. POL carries several adjustable Panhard bars for 1960-72 Chevy/GMC trucks. The 1963-72 standard adjustable bar works with factory or lowered ride heights, while the Deluxe C10 version is specifically designed for lowered trucks and is identified by POL as an option for air ride applications.
What is different about the Deluxe 1963-72 C10 Panhard bar?
The Deluxe version uses a trailing-arm mounting arrangement and has a broad adjustment range. POL notes that it works with lowered trucks and air ride vehicles. It does not work with factory C20 trailing arms because of their reinforcement plates, and it is also incompatible with heavy-duty deep differential covers.
Are Panhard bars available for classic Chevy Impala models?
Yes. The collection includes an adjustable Panhard bar for 1959-64 Chevy Impala and another for 1965-70 Impala, Belair, and Biscayne models. POL also carries rear upper control arm and Panhard bar packages for several full-size Chevy year ranges.
Can I replace only the Panhard bar bushings?
Yes, for compatible applications. POL currently carries polyurethane bushing kits for 1960-72 Chevy/GMC trucks, 1959-64 Impala, 1965-70 Impala, and 1982-92 Camaro/Firebird. If the bar itself is still suitable for the vehicle, replacing worn bushings may allow the existing assembly to remain in service.
What should I check before ordering a Panhard or trac bar?
Confirm the vehicle year and model, then inspect the rear suspension currently installed. Check ride height, axle position, trailing arms, mounting points, bushings, and differential cover clearance. If the vehicle is lowered, uses air ride, or has modified rear suspension, compare those changes carefully with the individual bar's fitment requirements.
