Making Vehicles safer and high performance enjoyable !




What is sulastic ?
SULASTIC is an elastic (rubber spring) suspension that reduces and in many cases totally removes the vibration and shock caused by the leaf spring suspension, improving safety and overall handling of the vehicle.

Key benefits
  • Increase in vehicle stability by 20% to 30% increasing the angle for turn-over by 4 to 6 degrees
  • Reduction in vehicle vibrations by 60% to 80% while signifiantly reducing excessive tire temperature caused by excessive vibrations
  • Reduction in braking distances by 10% to 20% keeping all 4 tires on the road during braking
  • Increase in driver control by stabilizing vehicle weight over all 4 tires

Q. Will these affect my ride hight or load capacity of the truck?
A. The answer to your question is no, the Sulastic does not affect either the height or the loading capacity of your truck at all. The product is designed to fit your truck and only help you with the vibration, balance and the over all driving control

Q. What type of warranty do you offer?
A. We issue a one year warranty against material or labor defects, and a 30 day money back satisfaction guarantee.

Q. What could happen to my vehicle if the Sulastic Rubber Spring breaks?
A. The only way the Sulastic Rubber Spring can break is if the rubber is detached from the steel. If this happens, then only thing that would happen is that the spring's work limits would make a harmless metal cranking noise.

Q. Could I have an accident if the Sulastic Rubber Spring fails? A. No, the Sulastic Rubber Spring is attached directly to the vehicle chassis. Therefore, any eventual breakage would never affect the vehicle's axis

Q. Do you sell the Sulastic by piece or by the set? A. We sell it by set, the set is of two Sulastic.

Q. Could the truck bed hit the tires if one of the Sulastic Rubber Springs breaks? A. No. There's a rubber separation between the axis and the chassis that protects the axis, making it impossible for the tires to have contact with the truck bed. This situation might be different for trucks that have been modified with lowering kits, larger wheels, etc.

Q. Is the Sulastic Rubber Springs' performance affected by extreme weather conditions? A. No, the Sulastic Rubber Springs have been designed to perform from -22 degrees Fahrenheit up to 140 degrees Fahrenheit.

Q. When should the Sulastic Rubber Spring be replaced?
A. Our springs are manufactured to last at least 10 years. This period could be shorter if the vehicle is used constantly under severe or off-road working conditions.

Q. What type of maintenance is required?
A. The Sulastic Rubber Springs don't need to be cleaned or lubed, only the bushings have to be replaced every three years.

Q. Can the Sulastic Rubber Springs be rebuilt?
A. No, only the metal parts can be recycled.

Q. Is the Sulastic Rubber Spring affected by frequently riding over muddy conditions, sand, and / or se A. No, the Sulastic Rubber Springs are protected by an anti-corrosion coating, and has no parts where leaking can occur. You should only rinse them with water once in a while, when washing your vehicle.

Q. Can I weld the Sulastic Rubber Spring?
A. No. The rubber can detach from the metal or get damaged when exposed to temperatures over 250 degrees Fahrenheit.

Q. Can I install my existing Sulastic Rubber Springs on another vehicle?
A. It is possible, assuming that your new vehicle uses the same Sulastic Part Number. Please use our part locator to verfiy compatibility.

Q. Will the installation of a Sulastic Rubber Spring void my vehicle's manufacturer warranty? A. No. Manufacturers, distributors and sales representatives have to honor the warranty. However, they are not forced to pay for any damages that might be caused by the Sulastic Rubber Spring. For these purposes, Sulastic has a separate liability insurance program.

Q. Does it lift or lower my truck when the sulastic is installed?
A. In some vehicles it can lower or lift the truck no more than 1/4 an inch.

Q. For how long have your product being in the market?
A. Our product has been in the market for more than eight years.






Testimonials:

-MuddinDirty
Got mine on Friday. WIFE Approved!!!! They really help with the "kidney shot" bumps, almost not even there. Best mod on the dually yet until the lift gets done!!!

-EROracing
Yes I will agree with the above statement. These really helped with the concrete freeway as well as everyday jarring bumps money well spent. Thanks Nick.

-hookdOnDmax
NorCal Nick installed the Sulastics for me last week. They eliminate that immediate spring-to-frame harshness induced at every bump. They also eliminate the annoying vibration in the leaf ... the feedback-whip vibration (spring-stutter?) immediately after a bump. The Bilsteins had already tamed it quite a bit, but the Sulastic shackles totally damp it out.

-Denali02
Two weeks ago NorCal Trucks installed the Sulastic Shackles. I wanted to drive it a few hundred miles and before the assessment.

To clarify, the truck is still a truck. I can't say it's a significant improvement but enough to reduce that gut wrenching harshness from the rear and the rapid bunny humps. Much softer, enough to take the edge off which is what I was looking for especially when the gas tank was empty. Wish I would of done this long time ago and well worth the investment.

-RYDNHI4x4
I just got the Sulastic Shackles put on yesterday. And let me tell you what huge difference to the now what stiff bounce in the rear. Soon as I drove away from Nick's shop and went over the speed bumps. WOW. I actually feel like I am driving a car. No more going over bumps, dips and have the rear end feel like it just hopped side ways on you. I would definitely recommend these products if you’re looking for a better quality ride and smoothness to your truck. Major difference.

-INSman
Thank you Nick for the Bilsteins that seem to be perfectly valved for my stock setup along with the sulastics that got installed today together and WOW, what a difference !!! Not my Lexus, by absolutely makes me happy about driving the truck again and I know the wife & kids are going to appreciate it as well on our next road trip...

-HotRodSS
I have had the Sulastic springs installed for a while now and I was very pleased with the ride improvement. One way I could describe it is that the rear suspension is similar to the front now when going over bumps. It is much smoother as opposed to the harsh jar that was there before. They are made much heavier than the stock shackles also. I would recommend them if you are looking for a smoother more "car-like" ride from your pickup. Thanks to Nick for a great product.

-dh515
Have had the Sulastic springs on for a couple of days now. Made a very noticeable difference in ride quality and they were well worth the price. Much smoother ride and less jarring from the back. BTW, Jeff at Nor Cal Truck was very helpful and gave good information. One of the better products I've put on my truck.

-Mad Maxx
Got the Sulastic Shackles Installed and damn!! What a difference.

I got a perfect spot my my house to test out Suspension stuff, a Railroad Crossing, it's not terrible, but it makes you slow down to go over it.

When my suspension was 100% Stock, I had to hit the brakes and slow down. Then I put on the Bilstein's, and I could keep my speed, just let off the gas as I went over them. Now with the Bilstein's coupled with the Sulastic's, I stay on the gas and barely even feel the bumps and dips. But all-in-all...Bilsteins coupled with Sulastic's WILL give you a 1500-esque ride.

Sounds like an awesome product might be interested in some when I get done with some other things I'm doing now. Will those work on the front and rear leaves?

Maybe they'll come out with some for the front one's to put were the shackle goes on the back of the spring.

Sounds like from the testimonials and the videos that it makes a big diff.

I have found that there are MANY sections to the front end of the leaf trucks that can reflect a bad ride if not set up ride. You be very surprised to how much you can clean up a front leaf truck with some checking of making sure there is NO binding points.

Says only 350's, will it also fit an ex?
Yes I have those also ...sorry I left it out

Just my 2 cents on sulastic rubber shackles. If I can't notice a difference with my bad back, I doubt anyone can. It was a major pain to install them with just jacks and stands in the drive, especially if you have big hands. I believe I have to agree with a fellow that posted his comments about them in the suspension forum. "I literally had to strain to notice a difference if there was one at all". I bought them because I had a 2 level back fusion and heard they smooth and take the harshness out of the 3/4 ton ride. My back can literally notice a 2 lb difference in my tire pressure, but not these. If I didn't put them on myself, I wouldn't have known anything had been done to the suspension, no kidding.

As much of a hassle as it was on my back to mount them, I will most likely keep them on just to avoid all the BS I went through mounting them. I may just eat the $340. As for all of the benefits they claim like shorter brake distance, better handling, reduction in vibration, etc...I noticed no change in those characteristics.

So in my opinion, they did nothing for me, I may just take them off anyway and send them back to get a better riding shock all the way around as that will cost about the same. I am sure the Ranchos that came with the FX4 package are not the greatest.

Not trying to slam the product, just shoot straight as to what I noticed, or lack of.

Scott?? You had emailed me with install problems you had I think?? Sorry I was out due to a new born my wife and I where having:woot:

I am sorry you didn't "feel" a difference. Man we ship a crap load of these and I always get great feed back. Maybe I can help to see if we are over looking something on the install or other suspension set ups that is avoiding you from experiencing a great ride like the others that have used the product.

Is the truck stock or lifted?
What shocks are you using/ miles on them?
Possible where the shackles over tighten at time of install?

Please help me with more info so I can help you. Yes:) I ask a crap load of questions because we might sometimes learn from others that had issue's to better our knowledge for the next customer.


Thanks,
Nor-Cal Nick

Honestly, the rear of the 3/4 ton trucks gives 90% of your ride. The only way to achieve it is by replacing the stock leafs w/ aftermarket leafs (Deaver, National) along w/ a good shock (preferably a shock you can valve for your driving terrian along w/ the spring rates of leafs and coils).

You have never been in a truck with these shackles. They are great for the guys that still have OE rear springs and want to help there ride. I have only had 1 guy send back the shackles and he was this forum (Ford). I turned around and installed them on another Ford and the customer was really happy, he had almost changed his springs out to a Deaver but this was a cheaper route. Don't get me wrong Deavers are GREAT but a lifted spring doesn't always work for every truck owner.

Hey nice name buy the name:thumb:

I hope my turn out to be a success when I get them installed. It looks like it will take longer than a half hour do to my truck being a spring lifted truck and using a bottle jack to force the springs down enough to line up the bolt holes and get the shackles on.

Reviving an old thread.

Are you guys still happy with these? Anybody try SumoSprings? My truck is getting hard to take as I get older and have developed a couple of herniated discs!! I would like to try something that would take the harshness out of the bumps. I know it will still be a truck but if I could just take that initial jolt out of the bad poyholes I would be happy. I have brand new Gabriel shocks on the truck.

I have an 03, crew cab, long bed, 7.3L, 4 x 4.
