LS Stainless Coolant Crossover Steel Steam Vent Kit
One of our Most POPULAR products. Our Stainless Steel Steam Vent System connects the 4 corners of your LS engine to remove trapped steam and get it where it needs to go. Steam / Built Up Pressure creates elevated temperatures.
The LS engine has 4 corners for a reason and we suggest connecting them on ALL modified engines using whatever means are possible. When steam gets trapped pressures rise, when pressures rise it creates an unsafe tune condition which can lead to pre-detonation, head gasket failures, lean cylinders causing piston failure etc. Whether you are upgrading your LS1 Camshaft or adding boost or nitrous, this is a must have!
This system has proven itself time and time again in the real world with our customers. Adding this and our other style of steam vents have taken problematic combos where #8 and 7 cylinders were having gasket or lean issues and cures them.
It not only works well but looks amazing as well. This setup combines CNC aluminum manifold and corner ports with 304 stainless steel line. Each kit is hand built. Aluminum blocks are offered in black anodized finish.
Our Stainless steel system is hand built and 100% made in the USA. We take pride in fitment and quality of this kit. Gaskets come at no extra charge.
This system bolts to ALL series LS engines. This system has been tested with the following intakes and is compatible with Texas Speed SR series intakes, Holley Hi Ram, Holley Sniper, Edelbrock Pro-Flo XT, Edelbrock Super Victor, Frankenstein intakes, Edelbrock Victor Junior, & Stock Style Plastic Gen 3 Truck Intakes. Will fit nearly any of today's long runner style intakes.
*Note this kit will clear factory knock sensors on Gen 3 engines.
*Will not fit with Holley 300-132 or 300-129 Intake.
*Note LS3 L92 and other heads have the rear ports blocked off. This block off is a simple aluminum plug. You can knock this plug out from the bottom out (if heads are off) with a punch. It can also be carefully drilled out as our corner blocks seal off the top flat surface. DO NOT enlarge the hole size overall. Care must be taken to not let aluminum chips fall into the head passage so we suggest multiple careful drills with vacuuming in between and possibly greasing the drill bit.
It went on like a dream. Your lines & angles were super close. I would gladly recommend to anyone interested in one.
Well made kit. Easy to assemble and looks great! Much sharper than a bunch of hoses running everywhere and makes it very easy to bleed the cooling system.
Exactly what I expected from Motionworks ,excellent full kit with flawless craftsmanship
Looks and fit great!
Great experience from purchase to install. Great customer service along all aspects.
Kit is super rad, fits like a glove, and looks killer! Made in Iowa, rad.
Very happy withe product awesome piece
Doesn't get any neater than this Motion steam port kit. If you are a neat freak like me, it's a must have.
Damn Good looking!!!!
I installed your coolant crossover kit, lower valley pan and valve covers so far have plenty of other Motion Raceworks parts to still go on the build. The machining and workmanship is top notch. Only thing I would ask is with the valley pan kit of pay a few bucks more to have nice hardware with it. Next CO2 Kit, #16 AN Billet pass through, smart coil brackets, C6 Steering column, steering wheel and buttons.
Thanks for building Bad ass parts see you at Raceweek!
