Designed for 10.200" tall-deck blocks, this kit delivers a 4.500" stroke paired with 4.600" bore forged pistons to achieve 598 cubic inches of displacement at a low-compression 10.0:1 ratio — making it an ideal foundation for power-adder and forced-induction builds.

  • Pistons: Manley 2618 forged aluminum Platinum Series flat top pistons — 4.600" bore, 1.245" compression height, -3cc dome volume
  • Wrist Pins: Manley premium chromoly wrist pins
  • Performance ring set
  • Premium rod and main bearings

it was veryeay to order very good prices fast shipping

Awesome prices

It took exactly a week for the part to be shipped because the part came directly from the supplier. But the price was the lowest around.

easy to use site.

Once I've ordered from autoplicity and the part was wrong. I'm giving them another chance and the check out was much easier. Things were updated and now it's smoother so hopefully everything will go well this time

I got the part I ordered and will be having someone install it soon looks just fine and I love the chat feature as well.. thinking about buying brake shoes now.. a lot of savings

The company that makes this product has a non iPhone friendly interface. Autoplicity was easy to navigate using mobile.

I found them doing a search for a clutch kit, they are hands down one of the easiest companys to work with and the prices cant be beat..... I looked everywhere

Good

Great

Easy to use

Nice website, easy to use.

I ordered a Thule 9001 order number 27522 bike rack for my vehicle late Monday evening and received the product on Friday. Quick shipping with the free shipping option. Very happy with purchase and with autoplicity! Will def order from them again! Also the price was 30 to 40 bucks cheaper with autoplicity.

Easy to purchase online.Would buy from again. Fast shipping.
