Collection: Classic Performance

Who Classic Performance Products is

Classic Performance Products, often shortened to CPP, is based in Placentia, California. It calls itself the industry's "go-to" specialist in steering, brakes and suspension products for classic cars and trucks. Its part finder covers Chevrolet, GMC, Ford, Dodge, Buick, Pontiac, Chrysler and Jeep, plus Mustang II style front suspensions, and its catalog leans toward classic GM cars like the Bel Air and Nova and the 1973-87 squarebody trucks. Lower HQ is not a CPP dealer and has no relationship with the brand.

We have 115 Classic Performance parts live. Most titles give the part type and part number, and the vehicle is in the listing details.

Classic Performance lines we carry

We also list a few CPP brake line kits, hubs and bearing kits, which are not suspension parts but often go in during the same front end rebuild.

Fitment coverage

Many CPP part numbers start with the year range they fit. For example, 5557 parts are listed for 1955-57 Chevrolets and 6774 parts for 1967-74 Chevrolets. Use that as a guide, then confirm the model in the listing details, since one year range can cover several GM bodies. The vehicles our listings name most:

• 1955-57 Chevrolet (Bel Air, 210, 150): control arms, steering linkage, idler arms and a high-clearance sway bar.
• 1958-64 Chevrolet: tubular arms, rear trailing arms, lowering coil springs.
• 1962-67 Chevy Nova: tubular control arm kit and front subframe kit.
• Chevrolet and GMC trucks: 1955-59 drag links, 1961-72 lowering blocks, a 1976-87 lowering kit and brake line kits for 1960-66 and 1967-70 trucks. See C10 lowering kits.
• 1967-74 Chevrolet and 1970-74 Pontiac: tubular and stock-type arms, steering linkage kits.
• 1963-74 Dodge and Plymouth: stock-type upper control arms.

How to choose CPP parts

Stock-type or tubular arms

Stock-type arms are for a correct restoration or a driver at stock height: new metal, bushings and often ball joints in the original shape. Tubular arms are stiffer and are aimed at lowered and performance builds, where the stock arms' geometry and rubber bushings hold the car back. If the car will be lowered, tubular is the more common pick. Compare arms from other brands on our control arms page.

Lowering springs, a lowering kit or coilovers

Lowering coil springs are the low-cost way to drop a classic car or truck a couple of inches. A complete lowering kit adds the rear parts, such as blocks or leaf hardware, for an even stance. A dual adjustable coilover conversion costs more but lets you set the height and damping, which is worth it on a car that will be driven hard. Our coilovers vs lowering springs guide covers the trade-offs.

Steering linkage first

On a 50 or 60 year old car, worn idler arms, tie rod ends and drag links cause most of the wander people blame on the suspension. A complete steering linkage kit is often the best money you can spend before any handling upgrade. See tie rods.

Classic Performance vs alternatives we carry

• Detroit Speed aims higher, at pro-touring builds, with caster camber kits, anti-roll bars, a coilover kit and a steering rack. Our CPP range is bigger and covers more stock-style rebuild parts. See Detroit Speed.
• Belltech is the deeper choice for lowering later GM trucks, with complete kits sold with or without shocks. See Belltech lowering kits.
• QA1 sells coilovers and shocks if you want a different damper brand. See QA1.

What else you'll need

• Ball joints if your control arms don't include them. See ball joints.
• Shocks matched to ride height when you lower a classic.
• An alignment after arms, springs or steering parts, set for radial tires.

Control arms, springs and steering linkage are home-garage jobs with a spring compressor and the right tools. Subframe kits, leaf spring relocation and some coilover conversions are better left to a shop. Warranty terms are set by each brand.
