All the quality, reliability, and workmanship you have relied upon for years from the Compstar lineup is taken to the Xtreme--Callies Compstar Xtreme connecting rods. Specifically designed for power adder and diesel applications, these rods utilize the same proven 4340 material and ARP 2000 or L19 fasteners. Strength was added by thickening up the flanges of the H-beam and a reduced depth-of-cut towards the center of each rod, then non-essential weight is taken out of the beam to help keep the overall weight of these Xtreme rods in check. Choose a set for your high output, boosted application.

Summit Racing™ precision cast cylinder heads are made from tough A-356 aluminum alloy and feature Permanent Mold "As-Cast" technology. Port accuracy is unrivaled--meaning CNC porting is not required to provide superior flow. The result is CNC-ported performance at a fraction of the price! We start with precision CNC-finished faces and bolt holes for accuracy and fitment. American craftsmen expertly size and install the manganese bronze valve guides and interlocking ductile iron seats before finishing with a competition-grade valve job. From there, the decks are given a final pass for superior finish. They are finish-assembled in the USA with top-quality components like PAC Racing springs, fasteners, one-piece 21 4N stainless valves, machined locks, Viton® seals and chromoly steel retainers. The final result is the performance you want and Summit Racing™ quality you TRUST!

COMP Cams introduces another industry first with their Max-Lift BSR shaft rocker systems, a bolt-in bushed shaft rocker system that increases valve train stiffness helping your engine achieve higher levels of performance. By tying all eight rocker arms together on a single shaft that fits in the stock rocker stand, COMP Cams has found a way to improve valve train dynamics, increase valve train stiffness and reduce deflection under extreme loads. The increased valve train stiffness created the BSR rocker system allows your existing cam to act like a larger camshaft by transferring more of the motion to the valve or the use of more aggressive, higher lift cams without losing control of the valve train. Take complete control of your valves with the COMP Cams Max-Lift BSR shaft rocker system.

COMP Cams short travel XD hydraulic roller lifters offer the advantages of both light pre-load and reduced oil volume, producing the most stable and highest-revving hydraulic lifter available. The XD versions feature heavy-duty tool steel pushrod seats. This adds strength and durability in extreme-duty applications, such as turbo drag cars and offshore powerboats. Certain engines respond better to a light lifter pre-load because it recovers more quickly from any bad harmonics in the valvetrain. Others work better with a heavy pre-load because oil volume is reduced under the plunger, which increases lifter stiffness. Now you have the best of both—with COMP Cams short travel XD hydraulic roller lifters. Order the model designed for your vehicle and engine application.
