Product Introduction

Improve your clutch response with a UUC clutch delay valve delete kit and upgrade your clutch lines to stainless steel in the process.

Features and Benefits Of This Product


Symptom: slow clutch engagement in manual transmission models.

Many owners of the cars listed above have noticed that they will get an excessive amount of clutch slippage and poor clutch engagement feel. This problem is most noticeable in situations calling for hard acceleration or quick shifting.

The cause is an added check valve (BMW calls it a "lock valve") in the clutch hydraulic circuit that is intended to slow the engagement of the clutch as you release the pedal. This hydraulic restrictor device is intended to smooth out the feel of shifts and potentially reduce the shock load on the drivetrain. The reality is it causes a high rate of wear on the clutch and excessive heat buildup in the flywheel leading to early failure.

A particular example is a "power shift" where the revs hang for a moment before fully engaging.

Replacement of the valve with the no-restriction replacement Unlock Valve in these cars results in very crisp and firm shifts. With the lightweight flywheel, the engagement is so positive and quick that passengers are pushed into the seat with greater force than ever before. Installation is as simple as unscrewing the original lock valve from the slave cylinder line, replacing it with the Unlock Valve, and bleeding the slave hydraulics


"Performance tune" your clutch control.

Stainless steel clutch line for improved clutch control


Original clutch line is rubber and can expand under the normal pressure of use. This expansion of the line negatively affects the clutch slave cylinder actuation, and makes for mushy pedal feedback.

UUC's Stainless Clutch Line is used to "performance tune" your clutch control. Inner Teflon® line is covered with woven stainless steel braid that will not expand under pressure.

The advantages include better clutch pedal feedback and superior clutch modulation. Results will be immediate.

Technical features:

line material fully compliant with DOT standards (MVSS-1006)

lines burst-tested to 6000psi
(maximum tested pressure from a BMW hydraulic system is 1200psi)

Teflon® inner line covered with a woven layer of stainless steel
and covered in an abrasion-resistant material (translucent blue plastic covering).

end pieces perfectly match original BMW design for easy assembly.
