COBB Tuning Air/Oil Separators

Factory crankcase ventilation systems recirculate dirty oil vapors back into the intake system causing an increase in crankcase pressure and a loss of engine efficiency over time. Thankfully, COBB Tuning has you covered with their well designed air/oil separators that prevent harmful oil vapors from entering the intake and creating a build up overtime. Decrease your crankcase pressure and increase your engine efficiency with COBB Tuning air/oil separators today! Other features and exclusive details include: * Efficiently decreases crankcase pressure by giving each engine vent port its own connection to the separator * Includes all necessary hardware for installation * Heat shielding on the crankcase breather and oil return lines * Coolant bleeder valve * Bespoke COBB color combination * Laser etched COBB logo

COBB Tuning Lightweight Crank Pulleys

COBB Tuning lightweight crank pulleys are CAD-designed and CNC-machined from billet 6061-T6. They're anodized to withstanding the toughest of under-engine conditions. These lightweight units can improve acceleration by reducing the rotational mass of the stock unit by as much as 4 lbs. The pulleys specifically maintain the stock diameter, so as to not under-drive and cause electrical woes for you; they also maintain the stock drive belt surface for a quick and easy install, by even the most novice of owners. Replace your factory main pulley with the performance of a COBB Tuning lightweight crank pulley. Order the model designed for your vehicle application.

Summit Racing™ Pro SBF and 303+ Hydraulic Roller Cams

Are you looking for a great made-in-the-USA cam for your 5.0L H.O. engine? Pro SBF and 303+ cams start with American bearing steel billets, the cams are precision-machined on a modern Landis CNC grinder with CBN diamond wheels for unmatched quality. Still thinking in terms of LSA and duration splits? These cams are designed on a whole other level by tuning each of the four valve events separately. Having a cam with attitude doesn't mean it has to be a dog at low rpm. We've tuned each of the four valve events to maximize power and torque in the range you will be running in. You CAN have your cake and eat it too. Summit Racing's™ affordable E303 Plus, B303 Plus, and F303 Plus are designed to tune easily and have the idle you're looking for. We've applied the latest lobe technology, and the valve events have been tweaked for modern intake manifolds and cylinder heads. The Pro SBF lineup ranges from a 204-duration daily driver tow cam to a 252 duration 8k rpm barn-burner. They are ground in fine increments to match your specific engine's top-end, displacement and intended rpm range. The lobes are stable to high-rpm and easy on the valvetrain, but we've added lift to take advantage of the high-lift flow of the latest cylinder heads. They are more aggressive with more overlap than their 303+ brothers for more attitude.

Chevrolet Performance Stock Replacement Non-DOD Camshafts

If you're looking for a cost-effective camshaft solution to delete that pesky DOD—Chevrolet Performance stock replacement non-DOD camshafts are the answer. They're designed to work with OEM valve springs/pushrods in the DOD-equipped Gen 4 trucks. These OEM camshafts are standard equipment on non-DOD 5.3L trucks. Since they come as a single-bolt style, new timing gear won't be necessary. Just swap cams and additional DOD delete parts (sold separately) and you're ready to roll! A fairly stock truck shouldn't require dyno tuning; however, the DOD system must be disabled in ECU for proper functionality. It is advised to consult with your tuner for more information. Order the model recommended for your year/make and engine application. Additional features include: * Hydraulic roller tappet cam * Single-bolt camshaft gear attachment * Computer-controlled compatible * This is the camshaft only (other components sold separately)

Summit Racing™ HDR Thickwall Chromoly Pushrods

Summit Racing™ HDR premium thick-wall pushrods are a great upgrade for your engine. Factory pushrods (and even .080 wall aftermarket versions) act like a pogo stick in a running engine. Not only is static spring pressure working against them, it's also the valvetrain inertial mass increasing with RPM. This reduces power and valvetrain life. While a .080 thin-wall pushrod may not break, it doesn't mean it's the best option. Enter the HDR's. Summit™ used FEA (Finite Element Analysis) in the initial testing. We didn't just compare them to thin-wall welded-ball factory pushrods, but with aftermarket models, as well. The results speak for themselves! * The Summit™ HDR 5/16 x .105 wall pushrods have 20 percent less stress and 25 percent less deflection than a typical 5/16 x .080 chromoly pushrod * The Summit™ HDR Pro LS 11/32 x .120 wall have 25 percent less stress and 28 percent less deflection than a typical 5/16 x .080 wall chromoly pushrod * The Summit™ HDR 3/8 x .135 pushrods commonly used in big blocks has 15 percent less stress and 20 percent less deflection than a typical 3/8 x .080 wall chromoly pushrod Summit Racing™ added other high-end features like 210 degree ball ends to cope with extreme lobe lift and clear the rocker and are available in multiple lengths. * HDR 5/16 pushrods are offered in common LS, SBC, and SBF lengths * HDR Pro LS 11/32 pushrods add .030 diameter AND .120 wall thickness over a 5/16. Although most LS engines came with 5/16 pushrods, 11/32 pushrods fit any stock or aftermarket cylinder head. The added thickness adds much needed strength to any LS cam swap or engine build. Being available in .025 in. increments allows for fine tuning of hydraulic lifter preload with the LS's non-adjustable rockers. * HDR 3/8 pushrods fit the LS7 and common BB Chevy combinations. They have .135 wall thickness for maximum strength. Pushrods are some of the best horsepower-per-dollar components in your engine, so step up to the HDR's for your build!

Summit Racing™ Pro Hemi Automotive Camshafts

Summit Racing™ Pro Hemi automotive camshafts are easy on the valvetrain and stable at high rpms. They work well with superchargers and nitrous, and will require springs, a tune, phaser limiter, and an MDS (multi-displacement system) delete. The smaller cams in this group have a noticeable lope and good power across the range, while the larger cams have a serious lope with strong top-end. Choose the one that best fits your purpose. Notes: * Pro Hemi automotive Stage 1 has a noticeable lope and works great in 5.7L as a daily driver. It makes good power through the range, and a tune and phaser limiter are required. A free flowing aftermarket exhaust is recommended. * Pro Hemi automotive Stage 2 has a mild lope and works great in a daily driver. It makes good power through the range, and a tune and phaser limiter are required. A free flowing aftermarket exhaust is recommended. * Pro Hemi automotive Stage 3 has a steady lope and is about the biggest cam to used in a daily driver. It makes great midrange and has good top end. It works with a factory converter, but a tune and phaser limiter are required, and free flowing aftermarket exhaust is recommended. * Pro Hemi automotive Stage 4 has a strong lope and works good in weekend hot rods. It makes great midrange and has very good top end. It is the biggest cam we recommend with a factory converter, and a tune and phaser limiter is required. A free flowing aftermarket exhaust is also recommended. * Pro Hemi automotive Stage 5 (or Stage 4 supercharged) camshafts provide a serious lope, great power in the mid-range, and a strong top-end. These cams require a tune, phaser limiter, an MDS (multi-displacement system) delete, and valve springs capable of .625 lift. We recommend a free flowing aftermarket exhaust and a 2800-3000 converter. Careful attention to piston-to-valve clearance is required. Fly cutting is generally not necessary. * Pro Hemi automotive Stage 6 (or Stage 5 supercharged) camshafts achieve the top stages in each of these groups, providing a serious lope, great power in the mid-range, and a strong top-end. Each of these special cams require a tune, a phaser limiter, an MDS (multi-displacement system) delete, and valve springs capable of .625 lift. We recommend a free flowing aftermarket exhaust and a 3000-3200 converter. Careful attention to piston-to-valve clearance is required. Fly cutting is generally not necessary.
