RacingDiffs LSD Conversion Kit for Saab FM and F40 Gearboxes
Transform your Saab's performance with RacingDiffs LSD conversion kit, designed to fit FM and F40 gearboxes. This kit delivers exceptional traction and control, eliminating the frustrating one-wheel spin commonly experienced with standard differentials.
Variant 1 (FM Gearbox):
Variant 2 (F40 Gearbox):
Forget about one-wheel spin! The RacingDiffs Progressive LSD Conversion Kit turns your stock differential into a 25% lock clutch-type limited slip differential (LSD). This Plug & Play kit is easy to install, providing all the necessary parts for a smooth upgrade.
No Material Compromise: Our kit uses high-quality tool steel, heat-treated and nitrided for superior durability and wear resistance. Unlike cheap alternatives like Phantom Grip, we’ve integrated friction discs between plates and spider gears to prevent the generation of metal shavings, a common issue with lower-grade LSD kits.
Maximized Performance with Progressive Locking: Designed using ZF LSD technology with Ramp Angles, our kit offers a progressive locking effect under load. You’ll experience smooth street driving, but when revs increase, torque is evenly distributed to both drive wheels for improved grip and performance.
Before installing the kit, inspect the inner surface of the small spider gears. Ensure they are smooth and undamaged from previous use. If necessary, have the gears machined for a perfect fit, preventing premature wear and breakdown.
