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.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.
