Energy Suspension – Body Cab Mount Set (Part No.3.4103R)

Body Cab Mount Set

from

$116.99
Will replace distorted and worn-out original rubber mounts to maintain car body and truck cab to bed alignment. Original rubber mounts are so soft they often crack, distort, and crush so badly they often fall off and aluminum body mounts are too harsh for street use that they tend to break and cause other components to break. Energy’s specially formulated Hyper-Flex polyurethane cab and body mounts combine the best qualities of both: they’re soft enough for a smooth ride, yet rugged enough for the most demanding road or track. Most sets have a strong zinc plated steel ring molded into them – for added durability and when the application requires it.

Product Features:
  • Assures Longer Lasting Cab to Bed Alignment
  • Replace to Restore Ride Height
  • Gain Durability
  • Stronger Than Original Rubber Mounts

Edelbrock – Performer 1412 Carburetor: 800 CFM, 4 Barrel, Square Bore, Manual Choke Inlet (Part No.1412)

Performer 1412 Carburetor: 800 CFM, 4 Barrel, Square Bore, Manual Choke Inlet

from

$538.99
The Edelbrock 1412 Performer Series 800 CFM manual choke carburetor is a precisely tuned, quality-built carburetor that can handle the rigors of daily driving while delivering consistent, reliable street performance from day to day. Several characteristics make the 1412 Performer Series 800 CFM manual choke carburetor an outstanding street performer. The first one is that metering rods are utilized to transition between circuits. The carburetor is unaffected by engine backfires, which means that there are no power valves to blow out, and the rods can be changed in seconds without carburetor removal or fuel draining. Secondly, the carburetor has the unique ability to “hold a tune”, so once it is tuned, the carburetor stay’s tuned. What this means to you is that compared to other carburetors, the performance remains consistent and the calibration stays unchanged. The lightweight all-aluminum body features a two-piece body that resists warping and is compatible with gasohol and blended fuels. The simple tub-type bowls and rear-pivot floats all contribute to a carburetor that’s reliable, user-friendly and is easily tunable for miles and miles of trouble-free operation. Dyno tests proved that the EPS 800 carb outperformed a Holley #3310 carb out-of-the-box by 26 ft-lbs. of torque and 22 hp on a small-block Chevy engine equipped with an Edelbrock Performer RPM power package

Product Features:
  • Edelbrock products offer improved performance and aesthetics for a broad array of vehicles and engines. ‘Proven performance’ is the philosophy by which Edelbrock was founded and it continues to this day with the highest standards for performance and quali
