SADEV Double Pawl Spring ST75-14 - Clio Cup & Twingo R2

Avoid Selection Failure on Your SADEV Sequential Gearbox

In motorsport, transmission reliability depends on high-precision details. By failing to replace your double pawl spring during periodic overhauls, you expose yourself to a major risk: vague gear selection or a complete mechanism jam. A fatigued or broken spring means an immediate end to your race, leading to repair costs far higher than the simple preventive replacement of this original SADEV part.

The Essential Component for the ST75-14 Gearbox

The ST75-14 gearbox, which equips the Renault Clio 2 Cup, Clio 3 Cup, and Renault Twingo R2, requires constant pawl tension to lock each gear. This spring (ref 0100801026) is manufactured from high-yield strength steel to withstand thousands of gear shift cycles. At Optimiz Access, we advocate the exclusive use of manufacturer parts to maintain the performance of your competition vehicle.

Preventing Mechanical Failure in Competition

Wondering if your current spring is still performing correctly? A loss of feel in the lever or a gear that "pops out" are warning signs of a double pawl failure.
