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.

Solid phone holder
This tesla magsafe phone holder was easy to install and works well, its compatible with any tesla and the magsafe magnetic ring is very strong and secure to my phone, and im pretty happy with that, it also is pretty adjustable so I can angle it so I can see it better, and overall is a great addition to any tesla. I do wish that the part connecting to the back of the screen to mount it was removable, because the only way to mount it is with the included adhesive and I didn't like that so much The build quality feels great and is well made. Overall though if you dont mind the adhesive mount its a great magsafe phone holder for teslas

Almost perfect
Style: Screen+Charger
Solid mount. I’ve tried other ones but they don’t sit as nicely as this one. It also has a lot of adjustments to allow for using it any way you need it to so it is very versatile. The magnet strength is really good and holds my phone really well. Sometimes it feels too strong which I guess is a good thing. The charging works well but I wish the cable was a little longer

Almost Perfect But With Workaround it Rocks
Style: Dash+Screen+Qi2 Charger, Style: Dash+Screen+Qi2 Charger
This works almost perfectly in my Tesla, with one small tweak for hot summer conditions. It holds my phone very well overall—I position it slightly off-center at about the 10 o’clock position. However, with a larger phone like the Galaxy S25 Ultra, the combination of weight and summer heat can cause the mount to slowly rotate as the suction cup loses some grip. I found a simple fix that works extremely well: applying a small amount of rosin (the same kind used for violin bows) to the friction point where the rotating arm meets the suction base. That added grip completely solved the issue. Now the mount stays exactly where I position it, even in the heat. Solid product, and with that minor adjustment, it performs exactly how I need it to.
