Racingline Lower Engine Mount Twin Dogbone Insert
The Racingline Twin Dogbone Insert is one of the most affordable and genuinely transformative upgrades available for MQB and MQB Evo platform vehicles. By filling the voids in your factory lower engine mount with a pair of precision-machined billet inserts, this kit stiffens the drivetrain mounting point and delivers a sharper, more connected driving feel – without the harshness of a full solid mount replacement.
Unlike single-insert solutions on the market, Racingline supplies both upper and lower inserts as a matched pair. This is an important detail: fitting only one insert creates bending forces across the mount that can lead to premature wear and eventual failure. The twin design balances those loads correctly, protecting the mount and your drivetrain over the long term.
What the insert actually does
Your lower engine mount (commonly called the “dogbone” because of its shape) controls all of the forwards and backwards rocking movement of the engine and gearbox. The factory mount uses large rubber voids to keep things comfortable, but those voids allow significant drivetrain movement under load. The Racingline inserts limit that compliance by occupying the voids with solid billet, giving you:
- Sharper throttle response and a more immediate feel from the drivetrain
- Crisper, more positive gearchanges with reduced driveline slop
- Near elimination of wheel-hop under hard acceleration and aggressive shifts
- Added protection against future mount wear and drivetrain stress
Expect a small increase in NVH (noise, vibration and harshness) – this is normal and unavoidable with any mount stiffening upgrade. Most keen drivers find the subtle drivetrain “growl” and added sense of mechanical connection a welcome part of the upgrade rather than a downside.
Which version do I need?
There are two versions of the factory lower mount fitted across the MQB range, so it is essential to select the correct insert for your specific car. Check the OE part number stamped on your existing lower engine mount:
| OE Mount Part Number | Insert Required |
|---|---|
| 5Q0 198 037 A | Version 1 (VWR150003) |
| 5Q0 198 037 F | Version 2 (VWR150004) |
Fitting the wrong version will not work – please verify the OE number on your mount before ordering. Use the vehicle lookup on the Racingline Shop or check the Vehicle Fitment tab for full application details. Fits a wide range of popular MQB and MQB Evo platform cars including many VW, Audi, SEAT, Cupra and Skoda models with 1.4, 1.8, 2.0 TSI and TDI engines.
Why fit the Racingline kit?
As an authorised Racingline retailer, we recommend this kit as one of the best value upgrades you can make to an MQB car. It is a straightforward bolt-in installation using the existing mount, requires no permanent modification, and the results are immediately noticeable from the first drive. For anyone running additional power, larger turbos, or simply wanting a more engaging drive, the Twin Dogbone Insert is a sensible first step that complements virtually every other performance upgrade.
