Description:
The AR1-HDR4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad rigid race discs are made with high-quality ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines.
Features:
- Feel: Light to moderate pedal effort, aggressive engagement, increased gear rattle
- Life: Moderate friction life, extended by ACT's exclusive diaphragm design, rigid design may increase spline wear
- Quality: Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance
- Recommended Use: Recommended for race use only
- ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability

Great product!
Size: 12 fl. oz. (Pack of 1)
Would recommend pouring oil into container after pouring in and shaking it up, great additive recommended by some old folks but I would have to say it’s just thick as molasses. Used in 2016 FORD F150 5.0 V8

Great for High Mileage vehicles
Size: 12 fl. oz. (Pack of 1)
Added into my 2014 Dodge Grand Caravan with 100k miles before a family trip and eliminated knock, slow starts and improved our gas mileage by about 10% I think! super easy to add to the oil and very happy with results.

Great assortment of clips—fits well and saves a trip to the dealer
Color: 40pcs
Picked up this 40-piece set to replace missing/broken push-type retainers on my bumper/fender liner area. The assortment is a solid value—having extras on hand is way cheaper than buying a few at a time locally. The clips I used snapped in securely and held the panel tight without rattles.
Tip: match the old clip’s size before installing (hole diameter + stem length). I tested a couple first to confirm fit and then finished the job. For basic trim/under-cover repairs, this is an easy, cost-effective kit to keep in the garage.
