Action Clutch Sprung multi-disc racing clutches are designed for high performance racers who push their vehicles to the limit while maintaining a level of streetability. The 7.25in Sprung Twin Disc race kits feature two sintered metallic race discs, formulated in the USA, which offer superior heat capacity and a smoother engagement than any other disc on the market. It also comes with a Ventilated 6061-T6 Billet Aluminum clutch cover design to help reduce overall weight and improve throttle response which is paired with our high strength steel pressure and floater plate. This added clamping force won’t require twice the pedal pressure.

Our single sprung hub features out patented fully enclosed spring retainer technology which is present in all our sprung single disc kits. This will ensure no matter how much abuse this unit sees, you will never eject a spring destroying your clutch kit or damaging critical components.

Action Clutch’s 7.25” Sprung Twin Disc race kits are designed to maximize performance under extreme conditions and are perfect for those looking for reliable power regardless of racing type. With added features like enhanced heat capacity and improved throttle response, these clutches will help you get off that starting line as quickly as possible and keep you running smoothly through the finish line.

At Action Clutch, every kit is quality checked by one of our experienced engineers (with over 60 years of collective experience) and signed off as safe before being released as a finished product. This gives you peace of mind knowing that your Action Clutch will perform consistently every time.

NOTE: Purchasing the wrong type of clutch kit for your specific engine power output can result in premature clutch failure, damage to the transmission and void warranty eligibility.

Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub. Unsprung clutch kits are not designed for daily/street use or any constant on/off engagement environment. This can be compared to running a marathon in sandals vs a proper running shoe. If you were to run the marathon ins sandals, you have no cushion or comfort and can cause injuries or wear you down faster than using proper running shoes.

Poli cleaners.
Material Type: Powder Ox, Size: 16 oz
Our trailer was extremely oxidized. I used the Poli wash and fiberglass cleaner, super easy. It removed the oxidation and made our trailer look new again. Next I will try the Poli sealer.

Works OK.
Material Type: Powder Ox, Size: 16 oz
With a lot of work and diligence (elbow grease), the product works at removing oxidation. I expected it to easily remove the old Poliglow as well. Still lots of work. It will NOT remove the brown water stains from the roof of my molded fiberglass camper. Product is OK, but does not work as easily as advertised.

It's extremely difficult and when it hasn't been maintained it looks like skin peeling after a sun burn

Poli-glow definitely works. The negative feedback is generally due to someone trying to remove poli-glow. It's extremely difficult and when it hasn't been maintained it looks like skin peeling after a sun burn. I purchased a 41' sailboat with poli-glow. The poli glow was flaking off and had to be removed. It wasn't fun. In the end, I bought poli-strip and used an orbital sander and wet sanded thru it. Then I used poli-strip, then poli-prep and washed it down. From there I used poli-ox and poli-prep one more time...I basically used poli-prep along with lots of water to wash boat down. The poli-ox when used thick, like a paste, ate through most stains once poli-glow was removed. It took two-three days of prep. Application took half day per side. I used two kits. Also bought the rectangular special applicator (far better than their mitt). Make sure to have lots of disposable gloves. I don't think the chemicals will harm your hands much...I didn't have gloves for much of the prep work, but gloves are a must when applying poli-glow. Othnerwise your hand get very gunked up.

Very expensive but worked no better than powdered cleansers
Material Type: Powder Ox, Size: 16 oz
My camper is a 2004 with oxidized paint and dark streaks from being out in the weather. I looked at reviews and there is a lot of hype about this product so I ordered some. I used this on an area of my camper to test it in case it didn't work and guess what...it didn't. It didn't remove the oxidation and black streaking any better than Ajax powder. In one place, when I used it as directed, it wore the paint down to the bare metal and didn't remove dark streaking in the surrounding area. The area I tested it on looked cleaner, but no better than the area I used Ajax powder on the day before. Very expensive for what it didn't do. I do not recommend this product.
