Pro Street
Designed for high revving street/strip applications. No other comparable product can compete with 600lbs* maximum open spring pressure whilst retaining factory size bolt-down hardware.
Manufactured and assembled in Australia using the highest quality materials and componentry consistent with those found in our Platinum race series.
Our wide range of true ratios allows you to achieve high lift without relying solely on your camshaft… a trend many engine builders and racers alike are adopting to relieve the inertia on lifters and pushrods generated by aggressive and often violent ramp rates required to make big lift.
Ideal for harsh street and strip applications, especially in place of the factory stamped steel GMH rockers that have seen decades of wear and tear. These rockers have got what it takes to last!
Why Choose Pro Street?
- Built to withstand 600lbs* max open spring pressure
- Oversize full-complement caged bearings designed for oscillating (rocking) loads, paired with oversize precision ground trunnions to reduce friction.
- Intricately balanced CNC billet arms ensuring vital valvetrain stability - focusing attention on the harmony of the entire engine.
- Extruded from aircraft grade aluminium, perfect for dissipating excess top-end heat.
- Proven bolt-on shaft mount design that mounts both inlet/exhaust to common shaft, effectively increasing footprint and clamp load twofold without any further cylinder head modification.
- Various ratios available, catering for every camshaft grind. High ratios allow for additional lift on stock and aftermarket camshafts.
Chrome moly steel hardened and ground roller tips of generous diameter (positively retained by internal circlip) preventing abrasion of valve tips and guides commonly seen with non-roller tip rockers. Allows for smoother, quieter operation. Maintains lash and reduces necessary and tedious engine maintenance.
Easy Fit Shaft - Adjustable - Suitable for both HYDRAULIC and SOLID camshafts
The original "bolt on" rocker. Simply remove old rocker gear and replace with the shaft assembly that bolt onto the original mounting holes with no modification. Tremendous rigidity
When installing adjustable rockers, double cork gaskets or taller rocker covers may be required. Please check clearance exists between Lash adjuster & Rocker covers at maximum lift.

Great Diapers
Size: Size 5 (33 Count)
These diapers have been a lifesaver for our family. They fit really well without being too tight and my daughter is comfortable. I love that they don’t sag easily and the stretchy sides help prevent leaks while still allowing my child to move around freely. The absorbency is impressive, especially during naps, and we’ve never had a blowout.
Another huge plus is the price. It’s hard to find diapers that work this well without spending a fortune, but these are a great value for the quality. They hold up just as well as more expensive brands, making them perfect for everyday use. I would definitely recommend them to parents looking for dependable diapers that fit well, absorb great, and are budget friendly.

Great bang for your buck
Size: Size 1 (50 Count), Size: Size 1 (50 Count)
Gotta say this is a pretty good diaper for the price! Not as soft as your luxury name brands but still very soft. Great absorption, no leaks, moisture stripe works. I like that they're mostly plain, I never understood why diapers needed to be "cute." The adhesion tabs work well, even though I did waste a diaper accidentally ripping one off. x)
As for negatives this diaper is narrower than all the other brands. Which is fine, it still fits my baby but I probably won't be buying these again unless im using them as an in between from nb to size 1

Comparable to Major Name Brands in price and quality
Size: Newborn (30 Count)
Good value for the price , comparable in value and quality of major name brands. Visually attractive and detailed product description on packaging. Newborn size package is very small and well packaged for easy storage. Diapers are made to fit comfortably to newborns body and manufactured to wick moisture into the diaper away from babies skin and so not to leak. They absorb a fairly good amount of liquid with no problems. The adhesive tabs stick well and do not come lose.

Lifesavers for sensitive skin!
Size: Size 6 (108 Count)
These are the only diapers we love after trying countless other brands. We struggled with so many issues, from diapers that felt cheaply made and rough, to constant leaks, or scents that caused horrible breakouts on my son’s sensitive skin. The Mama Bear Gentle Touch diapers are the first ones I have found that are truly soft, completely leakproof for us, and do not cause any irritation. They are lifesavers, and it is a genuine nightmare when we run out. They perform great overnight with no leaks, and they hold up well during active daytime play. We do get a few leaks, but it’s when my son chugs the water. I don’t think any diaper is saving that. The fit is consistent, the tabs are secure but still stretchy, and buying the bulk pack is a good value. If you have a child with very sensitive skin, I highly recommend giving these a try.

Wish we had these diapers with my first 3
Size: Newborn (120 Count), Size: Newborn (120 Count)
I am 39 been married 22 years and I have 4 kids. We have always had our kids seperated over the years and I have always used Luv's with my first 3 all other diapers leaked badly, never lasted long or gave the kids rashes. Luv's worked a little better on leaks at night none of the these diaper prevented leaks on sheets and bed while sleeping u always had to change there diapers multiple times a c there skin was always wet. With my first 3 kids we did not have the choices we have now days.
Well my 4th child is now 18 months and I had hopes of no more changing sheets in the middle of night. I finally got that with these diapers now I have learned all 3 above brands are garbage. Now they feel like paper to me and a waste of money. When I have ran out of diapers my husband has picked these diapers up at the local store. What happens wet clothes wet beds rashes. I never use these donate them everytime. When I see people say these are cheap diapers and they leak I have no clue what your talking about and my guess is they are buying the wrong size or not putting them on right. Alot of parents don't even realize they are using the wrong sizes for there child and if u are not buying the right size or put them on correct yes u will have leaks. The only time my sons skin is wet is when the diapers have been left on way to long and his peed alot. So if he slept 10 hours over night with no diaper change and he drank alot before bed this happens rarely but when he does this happens. Now while he was tiny no I didn't have this issue. I will say these are amazing diapers and I have tryed many diapers during this time more expensive and less these are the only diapers I will buy. It's also the first time ever with all my kids I didn't wake up many times with newborn having wet clothes and soaking the bed all thoughout the night some night soaking me too. There overnight diapers are really amazing too.
I would recommend these to anyone and I would never do so for luv pamper huggies I see those as a waste of money cheap diapers. These are perfect, know the correct size buy bigger keep diapers above belly button to many buy them to small.
