Product Description:

034Motorsport’s Billet Aluminum Rear Main Seal is designed to replace the failure-prone stamped steel factory Rear Main Seal on your 1.8T or 2.0T FSI Volkswagen and Audi. This Billet Rear Main Seal is CNC machined from 6061-T6 Aluminum and features an OEM Viton Elring seal with an integral tension spring to ensure a tight seal to the crankshaft.

The OEM rear main seal utilizes a poorly designed PTFE “sealing lip” which over time leads to an oil leak between your engine and transmission. The failure of a rear main seal can also cause crankcase pressure issues and possibly even misfires.

The 034Motorsport Billet Aluminum Rear Main Seal has been tested and proven to last under high heat and intense abuse and is an excellent upgrade for replacing your leaking rear main seal. It is also an outstanding preventative maintenance modification that can save you from future headaches of oil leaks, stained driveways, and reduced performance that a leaky OEM rear main seal brings with it.

Features:

CNC Machined from Billet 6061-T6 Aluminum
Gloss Black Anodizing
Sealant Groove for a Positive Seal and to Avoid Sealant "Squeeze Out"
"Screwdriver Gap" on Rear to Help with Future Removal
OEM Elring Seal With Integral Tension Spring
Seal pre-installed in billet housing, other options on the market force you to install this yourself
Installation Tool is Included to Make Installation Easier, and Protect the Seal from Damage
New Hardware (Grade 8.8)

Just wanted to share some love to Harry's euro and their team! Bought parts for my r32 and gti, they never disappoint. Love being part of the euro community in an ever so dominant jdm culture in New Zealand. Looking forward to bringing an rs3 in for tuning :)

Greg Davies

Great to have parts for my Range Rover so readily available in nz. Fast delivery and awesome quality products. Thanks guys!

Nick Ko

I took my BMW to get the downpipe installed. Harry's Euro has done an excellent job. I'm very satisfied with the quality of their work. The staffs are very nice. Highly recommended. 10/10

Sebastian Ramirez

I've been a loyal customer of Harry's Euro since 2017, and I can confidently say Scott and his team are the best in the game. Not only do they consistently offer the best prices, but the service is always top-notch. Scott is honest, transparent, and always takes the time to explain what’s going on with my car. Whether it's routine maintenance, unexpected repairs, or upgrades, I always know my car is in the best hands. Highly recommend to anyone looking for a reliable, expert mechanic!

Andrew Atkinson

Used Harry's Euro for years owning a Mk6R and now a Mk5 R32. Amazing service and delivery! R32 kit arrived today with some extra goodies! Pleasure to deal with the team!

Mark Barber

Hands down the best Euro shop in Auckland. They've looked after 2 builds of mine, and the parts, service and expertise has been top notch.

Marc Graham

Harry's Euros delivered platinum service from start to finish. The quality of the products is excellent, and the install experience was smooth and professional. If you want a lower cost acceleration boost ask Scott about a Pedal Box! Huge difference and very simple to use.

Quinn Ashby

Got some basic servicing and a Stage 2 transmission tune done today to match the ECU tune. The team was really helpful with information, communication via email, fit me in quickly, and offered fair, industry standard pricing for a specialised shop. Highly recommend, and I'll definitely be back!

Hayden Lawrence

Great service. Needed a replacement driver's side mirror glass for our old GTI. Harry's Euro had it in stock for a good price and shipped it next day. Very pleased with the transaction and will happily recommend and use them again.

SladeDaSlide

Been Working with Harry's Euro for almost 3 years now and I can highly recommend any auto-work or performance upgrades to be done by these guys. I've had my previous car and my current done by the team cheers to Scott and the boys for the work 🍻
