Product Details

Solid Lifter Conversion Kit for BMW M52TU / M54 Engines

This solid lifter conversion kit offers a proven, easy solution for high-performance BMW builds. Tested for several years in M50 engines making over 1000 whp and spinning to 9000 RPM, this system replaces the hydraulic function with hardened steel shims installed inside factory-style hydraulic lifters for improved reliability and precision at high RPM.

You have two lifter options depending on your setup:

  • 33 mm Setup: If you are using 33mm M52, M54, or S52 cam trays, you can reuse stock 33 mm lifters or install new OEM-style 33 mm lifters (such as those found under reference number 4200049100). Be sure to compare your existing lifters to the images in the provided instructions — only one style of stock 33mm lifter is compatible.

  • 35mm Setup: Alternatively, you can use M50 cam trays with 35 mm diameter Volkswagen-style lifters (similar to part number 050109309H). These lifters match the M50 VANOS lifter dimensions but weigh only 48 grams — the same as M52 lifters — making them ideal for race and severe-duty applications due to their larger internal piston.

Unlike traditional lash caps, these hardened steel shims install between the original lifter piston and cup, making it impossible for them to fall out of position. Note: When installing in an M50 engine, lifter trays from an M52, S52, or M54 must be used.

Each kit includes two shim thicknesses. You can fine-tune valve lash in 0.002" increments by alternating shim combinations. On average, each lifter will require 4–5 shims. Each kit coverages 24 valves. 12 intake and 12 exhaust.

Soft comfortable very good pillow
Size: King (Pack of 1), Color: White
I really love my new pillow it's great and comfortable. Yes, it has a little smell, but if you wash the pillowcase and put the pillow on the window for a day you won't notice anything anymore.

Best place for head
Size: Queen (Pack of 1), Color: White
Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

Soft and smooth cover
Color: Grey, Size: Body(20"X 54")
This is a nice pillow cover overall. The fabric feels good and it's comfortable to sleep on, especially compared to a more basic cotton cover. It is maybe a little thinner than I expected, so if you want something thick and heavy this probably isn't that. But for a soft smooth cover that fits and feels decent, I think it's worth it. No major complaints from me after using it.

These are the ones you want
Color: Grey, Size: Body(20"X 54")
May need to iron them out when wash/dried but my old ones still look new- soft, cooling, smooth, color is still great. Not itchy or cheap feeling. Buying a new set for family.
