The Full Torque Driveshafts' is a one-piece aluminum driveshaft for the F97 X3M and F98 X4M/Competition! A lot of work went into the design and manufacturing of the components for these driveshafts, and it has culminated in the ultimate driveshaft upgrade for your BMW X3M and X4M. 1350 series u-joints with direct-fit yokes! NO FUNKY ADAPTERS HERE!
A few of the components that give our driveshafts the highest quality and strength:
- Full Torque's exclusive 2024 alloy billet-aluminum direct-fit transmission flange (made in USA)
- Full Torque's exclusive 4140 chromoly direct-fit yoke for the differential (made in USA)
- SONNAX yoke-shaft/sleeve unit
- USA made 6061-T6 Aluminum drawn-seamless driveline tubing
- Forged 6061-T6 weld yokes
- NEAPCO forged solid-cross u-joints
Note: Best installed with Bolt Saver Plus and Bolt Saver 3 Differential Bushing kits!

This shaft eliminates the guibo, carrier bearing, and the crappy rear CV joint from your driveshaft. You will have a noticeable improvement in acceleration feel and responsiveness, as well as a massive gain in strength. These shafts have replaceable u-joints for easy maintenance down the road. These shafts are capable of 1,000+HP. Our direct fit design and high-speed balancing are the keys to our shaft's smooth operation. Direct-fit components offer true center line accuracy to the shaft, unlike our competitions adapter-style components.
This shaft comes with grade 10 hardware for the transmission flange. An OEM BMW pinion nut repair kit can be added for $35. Installation instructions will be emailed to you after ordering.
IMPORTANT NOTES
1) The larger diameter of this driveshaft may require trimming, bending, or tying some of your vehicles components to make proper room around the driveshaft. We will make known the common modifications in the installation instructions, however it is the SOLE RESPONSIBILITY of the customer to make sure nothing will rub on the driveshaft. It will ruin your driveshaft at your expense.
2) It is strongly recommended that you run stiffer bushings and/or bracing to minimize as much pinion (differential) wrap up and down movement as possible. Excessive pinion wrap will shove the driveshaft into components on your vehicle and cause damage to the shaft and your vehicle. Again, this damage is your responsibility.
