Product Details

The Howards Cams 91133 SportMax Lite Direct Lube Mechanical Roller Lifters are engineered for Chevrolet Big Block Mark IV Gen 5 and Gen 6 engines, delivering race-proven performance in a lightweight, high-quality design. These lifters are 0.300 inches taller than standard lifters, designed specifically for blocks with taller lifter bores.

Key Features:

  • Lightweight design—up to 20 grams lighter per pair than competitors (209 grams each)
  • 8620 heat-treated steel bodies for exceptional strength and durability
  • 9310 steel rollers on precision-sorted needle bearings for reliable operation
  • Direct lube high-pressure pin oilers included for improved lubrication
  • Stainless steel vertical crossbars for superior stability
  • Black oxide finish for corrosion protection
  • 0.842-inch diameter with 1.915-inch seat height

Built from precision-machined components and hand-assembled in the USA, these mechanical roller lifters combine the durability of the standard SportMax series with weight-saving machine cuts for improved valve train control at higher RPMs.

An easy to navigate website, great prices and efficient company. I will definitely check Autoplicity first for all of my automotive needs. From purchase to arrival I was well informed as to the status of my order.

Good Seller, very quick shipping and excellent transaction.

I saved over a hundred$ on a set of electric cooling fans. so the prices r great but it took 4 days to process and ship my order so well see how long it takes to get here but overall I would rather save money than get fast shipping

Good with no problems

First time shopping with autoplicity. Competitive pricing, free shipping. Parts delivered on time. Unfortunately experience with subsequent order wasn't as good.

Best price for the optima battery I needed for my boat, I will definitely add this site to my favorites.

They made a mistake with the shipping address, but, they took care of it very politely and professionally. Very nice. Thanks.

Very quick on shipping, at a great price.
