GK Tech S/R Chassis Z33/Z34 Transmission Conversion Braided Clutch Line – Banjo to Straight | Z33X-BAST

GK Tech’s braided clutch line for the Z33/Z34 transmission conversion in Nissan S and R chassis vehicles. Designed specifically for the swap configuration where a Nissan 350Z (Z33) or 370Z (Z34) gearbox is installed into an S13, S14, S15, R32, R33, R34, or other compatible S/R chassis — where the factory clutch line no longer reaches or seals correctly due to the different slave cylinder position on the Z33/Z34 transmission. This is the Banjo to Straight fitting variant — M10x1.0 Banjo fitting on the master cylinder end, M10x1.0 straight fitting on the slave cylinder end. Choose this variant based on the outlet location on your specific master cylinder.

Why a New Clutch Line Is Required for the Z33/Z34 Conversion

The Z33 (350Z) and Z34 (370Z) transmissions are a popular upgrade in S and R chassis builds — offering stronger internals, better gear ratios, and a closer-ratio spread than the stock SR20 or CA18 gearbox. However, the Z33/Z34’s slave cylinder is located differently than the factory S/R chassis transmission, and the factory clutch hydraulic line does not route correctly or reach the slave cylinder without modification. GK Tech’s conversion clutch line runs directly from the master cylinder to the slave cylinder in a single purpose-built line, engineered for the Z33/Z34 slave cylinder position in the S/R chassis engine bay. No splicing, adapting, or improvised routing required.

Fitting Configuration — Banjo to Straight (This Listing)

GK Tech offers this clutch line in two fitting configurations based on the outlet type on your OEM master cylinder:

• Banjo to Banjo: M10x1.0 Banjo fitting on both the master cylinder end and the slave cylinder end
• Banjo to Straight (This listing — Z33X-BAST): M10x1.0 Banjo fitting on the master cylinder end, M10x1.0 straight fitting on the slave cylinder end

Confirm the outlet fitting type on your specific master cylinder before ordering. The correct variant is determined by the master cylinder outlet — not the transmission.

Construction

• Assembled In-House in Australia: GK Tech assembles their braided brake and clutch lines in-house at their Australian facility — not outsourced
• Stainless Steel Fittings: M10x1.0 stainless steel fittings on both ends — corrosion resistant and compatible with standard clutch hydraulic fluid
• Stainless Steel Braided Line: Stainless steel braid outer sleeve — abrasion resistant and provides consistent line pressure without expansion under load (unlike rubber hydraulic lines, which can expand slightly under pressure, resulting in a soft or spongy clutch pedal feel)
• Teflon Inner Tube: PTFE (Teflon) inner tube — chemically compatible with DOT brake/clutch fluid, smooth inner bore for consistent fluid flow, and resistant to fluid degradation over time
• PVC Outer Protection: PVC outer coating over the stainless braid for additional protection against abrasion and chafing in the engine bay
