The RacingLine Twin Dogbone Insert limits the compliance of the lower engine mount by filling the large voids with our two Billet Inserts. All of the foreward/backwards rocking movement in your drivetrain is controlled by this Lower Mount – fitment of the RacingLine Twin Dogbone Insert adds strength to the drivetrain, helping to protect from future wear and breakages.

 

The Twin Dogbone Insert uses not one but two precision machined billet inserts to avoid the damaging bending moment that comes from fitment of a single insert. Many companies offer either the upper or the lower mount insert alone – we advise very strongly against fitting just a single insert. With a single insert, the twisting moment force on the mount becomes significant, leading to almost-certain failure. 

 

That’s why RacingLine only offer the Twin Dogbone Insert, keeping the forces balanced top and bottom through the mount and remove the risk of twisting forces destroying your insert.

 

The risk of wheel-hop under hard acceleration is almost eliminated as the whole engine and ‘box assembly is firmly prevented from juddering when wheelspin occurs and through aggressive gearchanges – especially valuable on FWD cars.

 

Fitment of the Twin Inserts will only add a minimal NVH increase to the car’s characteristics, but most keen drivers love the sense that they are more ‘connected’ to their car, and the gentle ‘growl’ that the mount conveys. 

 

Each Twin Dogbone Insert start life as a billet of T6061 Aluminium, before being precision CNC-machined into shape. Finished in RacingLine’s trademark black anodised finish for durability over many years. Easy, straightforward installation designed to be fitted without subframe removal means it just takes minutes.

TWO VERSIONS:

The factory mount comes in two version across MQB & MQB Evo models. To ensure fitment on the vehicle, please visually verify the mount you have, then select the correct insert below: 

  • OE part: 5Q0 198 037 A – You’ll require the Version 1 Insert

  • OE part: 5Q0 198 037 F – You’ll require the Version 2 Insert

     

  • We recommend a visual check to make certain you have the right version:

 

 

Version One

A near-circular central hole within the mount.

 

VWR150003

 

Version Two

A triangular central

void inside the mount.

WHY FIT TWIN INSERTS?

Why not just fit one of the two inserts? After all, many companies offer either the upper or the lower mount insert alone. RacingLine strongly advise against fitting just one insert. With a single insert, the twisting moment force on the mount becomes significant, leading to almost-certain failure. 

 

That’s why RacingLine only offer the Twin Dogbone Insert, with two billet inserts to keep the forces balanced top and bottom through the mount and remove the risk of twisting forces destroying your insert.

Single Insert in mount

Unbalanced reaction, twisting moment.

Twin Inserts in mount

Balanced forces; no twisting force.

Not full coverage
Size: Medium, Color: A-multicolor(6 Pack)
These are not full coverage and are the cheapest underwear in every way. The fabric is rough, and the seams around the edges of the leg openings are exposed. I ordered medium for my 28" waist and 38" hips. They fit... except for the buttcheek debut. I gave them to my 12 year old daughter to wear because she's not picky. Plus, they were cheap. She's happy. I'm still searching for full coverage undies. Update: The seller reached out regarding my review, and I'm impressed with their customer service. The cotton softened up upon washing and drying (no sand paper undies), and my daughter is very pleased with them.

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.

Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.
