Ferrari 348 TB Parts & Accessories

The Ferrari 348 TB was the original berlinetta variant of the 348 platform when it launched in 1989, replacing the 328 GTB with a significantly larger, more powerful 3.4-liter V8 and a new longitudinal transversale drivetrain layout that positioned the engine and gearbox end-to-end across the chassis rather than front to back. This transversale arrangement, indicated by the TB designation, differs in important mechanical detail from the later 348 GTB longitudinal models, meaning that transmission mounts, engine subframe hardware, and drivetrain-specific components are not interchangeable between the TB and GTB variants. Owners maintaining a 348 TB need to source parts specific to the transversale drivetrain configuration, particularly for anything related to the engine and gearbox mounting, cooling system routing, and suspension geometry calibration. The 348 TB remains a significant mid-engine Ferrari with strong performance and a character that rewards skilled driving.

Popular Upgrades

Timing belt replacement kits for the 3.4-liter V8 are the highest-priority service items on the 348 TB regardless of drivetrain variant, since the interference engine design makes belt condition critical. Bosch Motronic fuel injection components including fuel pressure regulators, throttle position sensors, and injector rebuild kits are the most common running quality service parts for aging TB injection systems. Suspension bushings, front and rear control arm ball joints, and rebuilt Bilstein or Koni shock absorbers address chassis wear that accumulates over decades of use on this platform. Brake caliper rebuild kits, Ferodo friction pads, and braided stainless brake lines are standard preparation items for track days and spirited mountain road driving.

Performance and Handling

The 348 TB's handling character generated debate among contemporary road testers, with the high polar moment of the transversale layout contributing to a tendency toward snap oversteer that caught drivers by surprise under aggressive mid-corner throttle application. The double-wishbone suspension at all four corners provides good geometric control under most driving conditions, but the transversale weight distribution places demands on driver smoothness that the later GTB's revised layout addressed through geometry recalibration. Refreshing worn suspension bushings and replacing degraded dampers significantly improves the TB's predictability, since correct geometry is essential for the chassis to behave as Ferrari intended. Proper tire selection and correct inflation pressure are more critical on the 348 TB than on many sports cars given the handling sensitivity the platform is known for.

What is the transversale drivetrain layout on the Ferrari 348 TB?

The transversale layout positions the 3.4-liter V8 with its crankshaft axis running across the car from side to side, with the gearbox inline on the same transverse axis behind the engine, similar in concept to the arrangement used in the 308 and 328 platforms but scaled for the larger engine. This arrangement concentrates significant mass close to the center of the car, which reduces the wheelbase of the car needed to achieve a given weight distribution but places all the drivetrain mass high and concentrated, affecting the car's yaw response. The later 348 GTB revised this to a longitudinal engine orientation with a rear transaxle, spreading the mass over a longer fore-to-aft dimension and lowering the center of gravity of the drivetrain assembly.

How should I address the handling sensitivity of the Ferrari 348 TB?

The 348 TB's handling reputation is closely tied to tire condition and alignment accuracy, and many of the reported handling issues on these cars reflect degraded tires, incorrect tire pressures, or suspension geometry that has wandered from factory specification through worn bushings or damaged components. Refreshing the suspension with correct bushings, properly valved dampers, and an alignment to Ferrari's factory specifications transforms the TB's behavior from unpredictable to manageable and rewarding. Driving technique adaptation also matters, since the transversale platform responds best to smooth, progressive inputs rather than abrupt throttle and steering corrections that can unsettle the rear end mid-corner.
