Street Cars - Race Cars - Drag Racing - Road Racing

The CylinderSupportSystem is simply the Best way to strengthen your OEM Aluminum Open Deck Cylinders, without the need of  full replacement sleeves.  Our proven method has racers around the world running incredible amounts of power reliably, while eliminating common issues associated with the aftermarket sleeving process. When running our CylinderSupportSystem you will no longer worry about full replacement sleeves sinking, leaking or shifting!

No Sinking - No Leaking - No Mainline Distortion - No Overheating

Our Support Rings are made from aircraft grade 6061-T6 aluminum which actually pulls post combustion heat away from the chamber, decreasing intake charge temps. Unlike thick cast iron replacement sleeves you will not have to worry about heat soak cutting your raceday or street cruise short.

Quality - Precision - Reliability - Proven Results

The Cylinder Support System process is NOT to be confused with the industry known “blockguard.” 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 blockguards cannot compete with the precision of our high quality CNC milling machines.

Shipping instructions:  

(Typical shipping cost for a bare 4cyl block is $60-$95 within the lower 48States)

Make sure you inspect YOUR block before shipping. We do not include a full inspection of YOUR block when performing the CSS process. Most important thing to check is if you have a cracked cylinder.!!! Wipe down cylinder and use a flashlight to see any potential hairline cracks.

Strip down the block completely. We only need the bare block. No Mains, No Plugs, No Sensors ect. (unless we are do the shortblock assembly)

This will also keep the weight down for shipping. HomeDepot, Lowes or U-Haul sell boxes. You can use a 14 x 16 x 20 or bigger box. Make sure it is a double wall box. Old boxes, bubble wrap or the 1” thick hard pink exterior insulation from Home Depot or Lowes will work. Whatever packing you use.

Make sure the motor is not free to slam around. DO NOT use peanuts. Tape box securely making sure the bottom has lots of extra tape.

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 jeff@cncwerx.com. 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.

Email: Jeff@cncwerx.com for pictures how to box a block using Home Depot goods.

PUT A NOTE IN THE BOX!!!!!

Even though we have most likely spoken I don’t want your order to be delayed because I didn’t remember something.

Please put a note IN THE BOX with the following info! Emailing same info to jeff@cncwerx.com is also a good idea.

1) your name

2) return address

3) e-mail address
