PDS Trans Hard Parts Kit - Stage 2 (ZF 8HP)

Stock ZF 8HP gearboxes cannot survive heavy boost or aggressive launching once you modify your car. High torque splits the factory cast hubs right down the splines and fries the stock clutch linings. That is exactly where this kit comes in. The Pure Drivetrain Solutions Stage 2 High Performance Hard Parts Kit replaces those weak OEM internals with severe-duty billet components and high-coefficient friction stacks.

Once built into your core, your transmission can reliably handle up to 1400 HP and over 1600 Nm of raw torque load. If you run a high-horsepower street build, a hard-driven track weapon, or a dedicated drag car with a ZF 8-speed, this internal overhaul package is an absolute necessity.

Features & Structural Benefits

Billet 7075 Aluminum C and E Hubs: Factory cast hubs fracture under sudden load spikes. PDS machines these replacements out of solid 7075 billet aluminum, heat-treats them, and finishes them with a hard anodize. They will not flex or split. Additionally, the internal fluid channels are re-angled to drive high oil volume directly into the clutch stacks, keeping internal temps stable during consecutive full-throttle hits.
Pure FSR Series Friction Plates: Every gear pack gets upgraded with high-coefficient friction linings. This specific lining material stops high-RPM clutch flare instantly and delivers immediate, positive gear engagement under heavy load.
Pure C6X Series Steel & Pressure Plates: Cut from premium Super Alloys, the A, B, and D pressure plates resist heat distortion and warping from extreme drag strip heat, keeping a flat profile for even clamping force.
Expanded Stack Capacity: PDS altered the internal clearances to squeeze extra friction and steel plates inside the assemblies. You get a massive increase in physical surface area and holding capacity without changing the external transmission housing dimension.

Box Contents

This is a comprehensive internal package containing a Billet 7075-T6 E-Hub assembly, Billet 7075-T6 C-Hub assembly, Super Alloy A, B, and D clutch pressure plates, a full set of Pure FSR Series frictions for all gear packs, a full set of Pure C6X Series steels, an upgraded D-Piston, a complete gasket and heavy-duty O-ring seal kit, and a brand new premium oil pan featuring an integrated filter element.

(Note: This is an internal rebuild kit. It does not replace the outer transmission housing casing; it replaces the weak links inside your existing gearbox.)

FAQs

Can I install this kit myself in my garage?

No. This is not a weekend DIY bolt-on project. Installing this kit requires a total teardown of the transmission assembly. Setting internal tolerances, dialing in precise clutch clearances, and proper component stacking require a sterile bench environment and specialized transmission building gear. Take it to an experienced performance transmission shop for assembly.

Does this kit come with transmission fluid or a torque converter?

No. This is strictly a hard parts structural reinforcement kit. It includes the upgraded hubs, clutch packs, pistons, seals, and a new oil pan with a built-in filter. High-performance transmission fluid and matching torque converters must be sourced separately.

Will this kit fix a transmission that is already slipping?

Yes, assuming your planetary gear sets, valve body electronics, and external case are not physically broken. This kit swaps out your worn-out friction plates, hardened seals, and weak factory hubs for fresh, high-strength hardware—essentially turning a tired stock core into a race-ready transmission build.
