The Cylinder Support System process is NOT to be confused with the industry known “block guard.” Why? Because it does not rely on the loose tolerance and taper(draft angle) of the factory casting. The Cylinder Support System process involves precisely machining the water passage, to accept our precision machined billet 6061 support rings. Our precision fit gives equal support pressure around the cylinders from the top of the support ring to the bottom of the support ring. Even the most finely filed/sanded block guards cannot compete with the precision of our high quality CNC milling machines.

NOTE: The CSS process will distort the top of the cylinders, so finish machine work is strongly recommended after the CSS process is complete!!!

Significant grime, oil and grease residue has adverse effects on our CNC machinery, particularly on the coolant and filtration systems. If a block arrives with caked on grime, oil and grease, then it MUST get Pre-Washed prior to machining for CSS. An additional fee of $75 will be added to your invoice if a Pre-Wash is required. **Note that a Pre-Wash gets rid of the major residue and oils. It is different than our standard Jet-Wash process where the block and mains get thoroughly washed. 

Turn-Around Time After Block Is Delivered: 

Turn around times are Estimates. We do our best to turn work around as quickly as possible. Thank you for you patience!!

  • CSS ONLY 1-4 weeks
  • CSS + finish machine work 3-6 weeks

When sending your block, it is assumed that you are sending a good buildable core which has been inspected. Inspecting cylinder for cracks, external damage, bearing surfaces and that the correct matching main caps/bedplate are with block. If you are unable to do these inspections, please contact us for a quote to inspect your block before any work is performed. CSS will not be responsible and you will be charged for work performed on a block if you opt not to have block inspected and it is determined after services are performed, that block is not buildable. 

Strip down the block completely. We only need the mains if you are having us do the finish machine work (i.e. honing cylinders). This will also keep the weight down for shipping. Home Depot, Lowes or U-Haul sell boxes. Use a box size which allows space for hard exterior foam around block. Make sure it is a double wall box. Thick hard exterior insulation from Home Depot or Lowes works the best to line all walls and brace block in place so it does not move around.

***DO NOT USE SPRAY FOAM UNLESS YOU HAVE HEAT RESISTANT FOIL TO COVER BLOCK**** Spray foam gets hot when it is hardening and will melt through garbage bags.

***DO NOT USE PACKING PEANUTS***

***DO NOT USE ONLY BUBBLE WRAP BECAUSE THE WEIGHT OF THE BLOCK WILL POP BUBBLES LEAVING IT UNPROTECTED***

Make sure the motor is not free to slam around. Tape box securely making sure the bottom has lots of extra tape. If you can't comfortably drop the box from your waist it probably isn't packed well enough.

Pictures to help guide you with properly boxing your block are available if you email ( [email protected] ). DO NOT USE an @icloud, @me or any other app email which can not accept large pictures because it will just get kicked back.

IMPORTANT!!!!  We send all packages “NO SIGNATURE REQUIRED” unless instructed otherwise. So, it is YOUR responsibility to know your surroundings and if you need to add signature required to the return label. If you require a signature, then add that to your note in the box or make sure you send an email to [email protected]. We absolutely will not cover any cost if package is stolen or misplaced if signature required is not requested. If you choose signature required and the package gets sent back to us, we will not absorb any of the costs involved and will add all additional fee's to your invoice.

Once your order is placed, we will email you a form to print out and include in the box with your block to be shipped in.

Simplicity at its best for the Tennis loving Girl
Color: White, Size: 7-8 Years
Pros: - this is a very chic and simple White Tennis dress - and stands out for its classic look! - The fit was perfect for my 4’ 8 girl and a very comfortable fit. - the dress also comes with a matching pair of shorties with a pocket / pouch for a phone or keys. - the fabric is very soft on the skin and is more technical in nature - means it can breathe well and perspiration vents out. - the material is also very stretchable - imp for playing the game and moving around daily. - I have put it through couple of rounds of washings and it has held well till date. Cons: Nothing that I can think of - durability and quality seem to hold , offering good value for money.

Nice modest sporty dress
Color: Navy Blue, Size: 11-12 Years
Nice soft dress with separate shorts. I love the color. We ordered a size 11-12 and it fits great. I wish it were a little more structured but it is very modest.

Adorable dress and fictional too
Color: Navy Blue, Size: 9-10 Years
This tennis dress is absolutely adorable and exactly what I look for in kids’ active wear. It’s modest, practical, and cute all at once! My daughter loves it, and the built-in shorts with pockets make it perfect for running, playing golf, pickleball, or just everyday summer fun. The material is soft, breathable, and moisture-wicking, so she stays comfortable even on hot days. I got size 9-10, which fits true to size. For reference, my 8-year-old is 52” and 63 lbs, and there’s still room to grow. This has quickly become a go-to outfit for summer activities because it’s stylish, functional, and kid-approved.

Stylish, comfortable, breathable, and fast drying! Perfect for active wear!
Color: Black, Size: 13-14 Years, Color: Black, Size: 13-14 Years
This tennis dress/set is perfect for my daughter. She can use it for tennis, golf, or just as an addition to her summer wardrobe. It fits true to size (though it does run a bit long), and it looks great on. The fabric is very soft and stretchy (a polyester and spandex blend). It’s also very breathable and quick drying, and I love that it’s machine washable. I also like that the shorts are not sewn in (instead it’s a two piece outfit). The shorts also have pockets large enough to fit tennis balls on both hips. The neckline is high and modest, and the skirt is loose and flowy. The dress and shorts are well made and durable too. Because it’s so lightweight, it’s great to wear even in hot and humid weather. The pullover design makes it easy to put on and take off. This dress is a great addition to any active girl’s wardrobe, and it’s a great value too. And it’s available in sizes from 7/8 to 13/14 and several different colors too!

Shorts are separate
Color: Pink, Size: 11-12 Years
This athletic dress is really cute and good quality. It fits true to size. I actually sized up because sometimes athletic dresses run more form fitting, but this one isn’t tight at all. The shorts are separate (I originally thought they were built in), and they do have a pocket, which is a nice bonus. The price is fair for what you get. There’s plenty of room for my daughter to grow into it and hopefully wear it for a few years. Overall, it’s comfortable and a great find.
