1960-87 Chevy GMC C10 C15 C20 Chassis Parts
Three generations of Chevy and GMC trucks fall within this year range, and each brings its own chassis layout and fitment requirements. A 1963 C10 may need a Panhard bar or driveshaft carrier bearing, while a later Squarebody can call for leaf-spring hardware, a C-notch, or different drivetrain supports. These chassis parts cover the mounting, clearance, axle control, and structural needs that change as the trucks and their suspension designs evolved.
From Coil-Spring C10s to Squarebody Chassis
The biggest chassis change across 1960-87 Chevy and GMC trucks happens underneath the rear of the truck. Early C10 and C20 applications use coil springs, trailing arms, and Panhard-bar axle location, while later Squarebody trucks move into a leaf-spring arrangement with completely different mounting and lowering hardware.
That transition changes what belongs around the axle. Earlier trucks can use adjustable Panhard bars, trailing-arm hardware, crossmembers, and two-piece driveshaft carrier bearings, while later C10/C15 builds bring leaf-spring hangers, shackles, C-notches, and traction bars into the picture.
Drivetrain hardware follows its own year breaks. V8 brackets divide between 1963-67 and 1968-72 applications, with transmission crossmembers, LT adapters, clamshell mounts, and other components supporting different engine and transmission combinations.
A few parts bridge those generations, including front shock relocation and sway bar systems, while others, such as the 1967-72 hidden hitch, belong to a very narrow chassis application. Across this collection, the rear suspension architecture and truck generation determine the starting point long before individual modifications do.
FAQ
What chassis parts are available for 1960-87 Chevy and GMC trucks?
POL currently lists 43 products, including engine brackets and mounts, transmission crossmembers and mounts, Panhard bars, C-notch kits, shock relocation hardware, leaf-spring components, traction bars, rear frame crossmembers, driveshaft carrier bearings, sway bars, and related chassis parts.
Do the same chassis parts fit every 1960-87 Chevy C10?
No. This range covers several generations and different suspension designs. Many components have narrower fitment ranges such as 1963-67, 1963-72, 1967-72, or 1973-87. Exact year and suspension configuration should always be confirmed.
Does POL offer an adjustable Panhard bar for Chevy C10 trucks?
Yes. POL currently offers an adjustable Panhard bar for 1963-72 Chevy trucks. It helps locate the rear axle laterally and provides adjustment for compatible suspension configurations.
Is there a C-notch kit for 1973-87 C10 trucks?
Yes. A bolt-in rear frame C-notch kit is available for 1973-87 Chevy and GMC trucks. It provides additional axle-to-frame clearance for applications where lowering reduces available suspension travel.
Are transmission crossmembers available for 1963-72 Chevy and GMC trucks?
Yes. POL lists a tubular transmission crossmember specifically for 1963-72 Chevy and GMC trucks. Match it to the vehicle, engine, transmission, and surrounding drivetrain configuration.
Does POL carry traction bars for classic C10 trucks?
Yes. Cal Trac traction bar kits are available for 1967-72 C10/GMC C15 trucks and separately for 1973-87 C10 applications.
How do I choose chassis parts for a 1960-87 Chevy or GMC truck?
Start with the exact year and model, then determine whether the rear suspension uses coils or leaf springs. Confirm the engine, transmission, rear axle, ride height, and any planned lowering or drivetrain changes before matching individual components.
