PRW Has Valvetrain Upgrades To Match Your Camshaft

PRW Has Valvetrain Upgrades To Match Your Camshaft

The General Motors LS-based engines respond very well to higher-performing camshaft swaps. But, the higher lift, heavier spring loads, and high-rpm operation can wreak havoc on those OEM rocker arm assemblies. Performance Racing Warehouse (PRW) offers several valvetrain upgrades engineered to work with the higher loads typically experienced when using a performance camshaft. PRW is known for offering great value on branded components you can trust.

PRW valvetrain upgrades

 

Racy Rockers

Whether you use your car for drag racing or simply want better street performance, one of the best ways to increase the durability and longevity of your LS engine’s valvetrain is to employ rocker arms with sturdy, upgraded trunnions. PRW offers trunnion rebuild kits featuring high-quality bearings or bronze bushings if you wish to upgrade your current rocker arms. Or you can purchase a drop-in kit that includes everything needed to seriously firm up your valvetrain. PRW’s 1.7 x 8mm rocker arm kits are available for 6.0L and 6.2L L92, LS3, and LS9 series engines. PRW also has 1.8 x 8mm rocker assemblies for GM’s 7-liter LS7 series engines.

PRW offers trunion upgrade kits and complete rocker assemblies with either bearings or bushings on the trunnions.

PRW offers drop-in rocker assemblies comprised of alloy steel rockers with heavy-duty side rails and additional modifications engineered to the nose of the rocker to help reduce drag. These beefy rockers ride on billet steel trunnions mated with either a full complement of high-quality roller bearings or bronze trunnion bushings. These drop-in replacements fit under stock valve covers and are designed for high RPM conditions. The PRW rocker arm kits also include 4135 alloy steel grade 12.9 M8 fasteners specifically designed to minimize interference when used in conjunction with higher lift camshafts.

 

Performance Pedestals

When you consider the forces at work on your engine’s valvetrain and the speed at which it is required to operate, it makes sense to ensure that those precision measurements are strictly adhered to. To help do that under the most severe, high-revving, and/0r boosted applications, PRW offers these billet rocker arm pedestal stands for LS engines.

These sturdy rocker pedestals are reinforced for more rigidity and are constructed from high-quality billet 7075 aluminum to ensure longevity and proper function. PRW offers heavy-duty rocker pedestals for GM’s GEN-III LS-based engines and GEN-IV LS3, L92, and LS9-style heads. An upgraded pedestal is also available for the Trick Flow series of heads and heads of a similar design.

These billet pedestals are designed to work with GEN-III and GEN-IV LS-based engines.

GM’s LS-based engines respond incredibly well to a variety of upgrades, but you need to ensure that your engine’s ancillary components are up to the task as well. These combined components by PRW are engineered to improve the reliability of your GM Gen-III/IV engine. They are a must whenever incorporating high-performance camshafts or higher-load valve springs. Head over to PRW’s website to see all the components they offer, or surf to your favorite performance warehouse to order those components built to give your LS-based engine the power and longevity you come to expect from these modern-day powerhouses from General Motors.
