Details

The M7 Speed lightweight crankshaft pulley will add power, acceleration and performance to your MINI. The lightweight crank pulley reduces crankshaft rotational mass which equals additional increased horsepower, torque and throttle response.

Design

This beautiful design is a result of advanced computer modeling and high precision CNC machining. Made in the USA from billet 6061-T6 aerospace grade aluminum alloy and finished with a deep black anodized coating and laser etching.

The Micro V-Belt grooves are machined to exacting SAE J1459 specifications for minimum belt slippage at maximum boost. Use this in combination with the M7 Speed 16 percent Supercharger Technology Pulley for maximum performance and boost yourself to the next level of MINI tuning and performance.

From the factory, the MINI suffers from no positive drive key on the crankshaft snout to drive the lower pulley. The factory pulley is press fit onto the crank. All aftermarket pulleys are slip fit at best and rely on the bolt to provide adequate clamp force to prevent the pulley from slipping.

The M7 Speed crank pulley is engineered with an interference fit onto the crankshaft eliminating pulley slippage on the crankshaft.

Features

  • Super Lightweight. Weighs in at 17 ounces (0.5 kg)
  • Save 6.2 lbs (2.8 kg) from stock
  • Reduces damper weight by an amazing 88.5 percent!
  • Prefect balance is achieved by symmetric design and high precision machining.
  • Industry exclusive interference thermal fit to eliminate high RPM slippage on the crankshaft.
  • Supplied with a brand new high quality ARP Racing bolt and precision ground flat washer
  • Micro V-Belt grooves are machined to exacting SAE J1459 specifications

Installation

Simple to install. Heat the pulley to 400 degreesF (205 degrees C) in your kitchen oven or using a small propane torch and the pulley will drop straight onto the crank.

When it cools it will shrink on to the crank. Finish the installation with the supplied ARP bolt and precision flat washer and presto...more power, more reliability and more overall performance for your supercharged MINI Cooper.

Made in the USA

Fitment Notes :
A larger 4 percent oversize speed increasing crank pulley will add just that little extra added supercharger boost and performance. This beautiful design is a result of advanced computer modeling and high precision CNC machining.

Made in the USA from billet 6061-T6 aerospace grade aluminum alloy with a deep black anodize coating, the M7 Speed 4 percent oversize - speed increasing pulley will provide a lifetime of reliable use.

Weighing in at just 17 ounces and supplied with a brand new high strength ARP bolt and precision ground flat washer, the M7 Speed Super Light crank pulley is best in class.

Each M7 Speed product is Engineered....Tested....and Proven to Perform!

FAQs

Will this require a tune after installation?

Bolt-ons like exhaust tips, cat-backs, and basic intakes usually don't. Larger mods — turbo upgrades, supercharger kits, headers — typically need an ECU tune to run safely. The spec sheet indicates if tuning is recommended.

Is this part emissions / CARB compliant?

If you're in California or another CARB-regulated state, check the CARB status on this page before ordering. Many performance parts are off-road or competition use only — if so, we say it clearly.

Will installing this void my factory warranty?

Modifications can affect manufacturer warranty on related components only — not your entire warranty. The Magnuson-Moss Warranty Act protects you from blanket warranty voids. If warranty matters to you, talk to your dealer before installing.

Can I install this myself?

Depends on the part. Bolt-ons are DIY-friendly. Turbo upgrades, headers, and supercharger kits need a professional shop. The product description gives a difficulty estimate.

Frequently Asked Questions

How do I know this will actually fit my car?

Every part listing shows compatible years, models, and trims. But here's the thing—trim packages and factory options can be confusing. If you're not 100% certain, text us at 772-277-2495 with your VIN or photos of your car. We'll verify fitment before you order so you're not stuck with an $800 part that doesn't fit. We've done this for 30,000+ builds. We've seen every weird trim combo and factory option. Takes us 2 minutes to verify, saves you weeks of headaches.

What if the part arrives damaged or is the wrong item?

We handle it. You don't fight with freight companies or file claims. Text us photos within 48 hours of delivery. If it's damaged or wrong, we ship a replacement immediately. You're not waiting 6 weeks for a freight claim to process. We eat the cost, not you. This is why we package everything like it's going to war. But if something slips through, we fix it ASAP. No forms, no back-and-forth, no "file a claim and wait." Just text us and we handle it.

Can I install this myself or do I need a shop?

Depends on the part. Emblems, front lips, some spoilers, bolt-on, DIY-friendly, you can do it in your driveway with basic tools. Full bumpers, hoods, wide-body kits, possible for experienced DIYers but most people take them to a shop for paint and install. Check the product description for installation difficulty. If you're unsure, text us. We'll be honest about whether you can handle it or if you should take it to a pro. We'd rather you know upfront than get frustrated halfway through.

What's your return policy if it doesn't fit or I don't like it?

30 days, unused parts in original packaging. You pay return shipping unless we sent the wrong part or it arrived defective. Once you install it, modify it, paint it, or mount it, we can't take it back. That's why we push so hard on verifying fitment BEFORE you order. We don't want you stuck with something you can't use. Text us before ordering if you're unsure. We'll confirm fitment so you never have to worry about returns.

Do you offer financing?

Yes. Affirm and Shop Pay available at checkout for orders over $50. Split payments over 3-12 months depending on order size. No hard credit check to see your options. Most people use this for big-ticket items like body kits, suspension setups, or wheel/tire packages. Rates vary based on credit. You see the monthly payment before you commit. Makes it easier to build now instead of waiting months to save up.

What if I have questions after I receive the part?

Text 772-277-2495. We don't disappear after you buy. Fitment questions, installation issues, "does this bolt go here" questions... we'll walk you through it. We've installed these parts ourselves or helped hundreds of people install them. You're not getting transferred to a call center in the Philippines. You're texting someone who's actually installed your part before. If we can't help remotely, we'll recommend a local shop that knows these parts.

Why should I buy from K2 instead of eBay/Amazon/other sites?

eBay and Amazon sellers don't answer fitment questions. They don't verify your VIN before shipping. They don't handle freight damage claims for you. If something goes wrong, you're filing disputes and waiting weeks. We're builders selling to builders. We verify fitment before you order. We handle damage claims same-day. We answer texts in minutes. We're not the cheapest, but you're not gambling $800 on whether a part fits. You're paying for support, verification, and someone who cares if your build goes sideways.

What does your warranty cover?

1 year against manufacturing defects: cracking, warping, paint peeling, hardware failure, fitment issues caused by the part being made wrong. Does NOT cover installation damage (you cracked it bolting it on), road damage (curb rash, rock chips), or normal wear. If it breaks because we made it wrong, we replace it free. If it breaks because you hit a parking block, that's on you. We're fair about it. Send photos and we'll tell you honestly if it's covered.

Shipping

Do you ship overseas?

Yes, we ship all over the world. Shipping costs will apply, and will be added at checkout. We run discounts and promotions all year, so stay tuned for exclusive deals.

How much does shipping cost and when will I see the total?

Depending on where you're located, small parts can ship free. Large parts like bumpers, hoods, and body kits require freight shipping. Uou'll see the exact cost at checkout before you pay. Freight usually runs $150-$300 depending on size and your location. We know it's expensive. We negotiate the best rates we can. If you're ordering multiple large parts, text us. We can sometimes combine shipping and save you money. We're not hiding fees in the final step. What you see at checkout is what you pay.

How long will it take to receive my order?

It depends on where you are. Orders processed here will take 5-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.

Roof rails a proper fit for my Ford Transit Connect - SWB. Some concern about the threaded connectors, wondering if rivnuts might offer stronger attachment.

Took 2 weeks to deliver with standard shipping. But well worth the wait. Install took 25 minutes with minimal tools and the lights look amazing. Fitment is perfect and the quality is excellent. Its kinda pricey but you get what you pay for with ntxglow products. Highly recommend!

Customer photo review of Spec-D Projector Headlights Ford F150 (04-08) Mark LT (06-08) Halo Black / Smoked / Chrome

They look amazing, and after using ChatGPT to help me understand how to install them (because the instructions were not very helpful whatsoever), I’m glad with how they turned out. My problems are that the lights aren’t too bright, the instructions weren’t helpful, and the arrival date was wrong, even if they arrived early.

Customer photo review of 1993-1997 Honda Del Sol Redclear Tail Light Lenses

This isn’t on K2, but the lenses came In which I was thrilled about. I’d already removed my OEM lenses from their housings. The passenger side lense fit well and mostly flush. The driver side, however, looks like it was slightly warped and caused poor fitment and what looks like a small dip in the red portion of the lense. I had no choice but to use them, as my OEM lenses were no longer usable. It can be very difficult to get replacement lenses in a timely manner for a Del Sol. I drive my car everyday, so I had to just go with it. Again, not a K2 issue but presumably the manufacturer.

Customer video review of 2003-2008 Nissan 350Z N4 Style Rear Bumper Cover - FRP

This rear bumper fits great the only thing is the trunk button on the bottom is cut a little to wide but that’s an easy fix it looks great and definitely makes the rear look more aggressive. I love it!

Customer photo review of Upgraded VANOS Oil Supply Line – M52 / M54 Engines (E36, E46, E39, E60, X3, X5, Z3, Z4)

The box was a little crushed, but the line was packed well and it wasn't a problem. The instructions are 3 pages of color pictures and lots of explanations. Very nice. The line itself is a very nice bit of kit with a swivel AN line end that allows a No-tension install. No leaks so far and it looks great. It came with new banjo bolts and copper crush washers. The only criticism I have is that I would have liked this hose coated in black so it disappears like the original, but it does look good, so I don't mind.

Not a fan of how thick the sides are on these vent pieces. I feel as if they would have been fine if they kept the oem size on the sides and just made them.
