Carquest Premium – Multi-Purpose Relay (Part No.RAA3258)

Multi-Purpose Relay

from

$67.99
Relays are electrical switches used to convert a small electrical load into a circuit capable of handling a high amperage load. Computers and small switches are not designed to carry the higher amperage requirement of a circuit that may have an electric motor, solenoid, or high amperage lighting fixture. Within a relay are contacts that are controlled with electromagnetism, when the circuit switch commands the device on or off, magnetism will pull or release the contact arm closing or opening the contacts within the relay that carry the voltage.

Product Features:
  • Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
  • Computer-Aided Design (CAD), laser scanning and 3D printing – utilizing Fused Deposition Modeling (FDM) and Stereolithography (SLA) – in the part design process ensures speed-to-market and a precise fit guaranteed.
  • Where applicable, robust circuit board design increases durability due to heat, shock, and random electro-magnetic pulses (EMP) and power spikes.
  • Tin plated lead frame prevents corrosion and ensures a reliable terminal connection under adverse ambient conditions.
  • 100% thermo-shock and vibration tested to ensure superior performance in extreme conditions.
  • 100% end-of-line tested to ensure accurate signal output providing product reliability, every time.

Radiator

from

$201.99
Carquest Premium Radiators offer one of the largest product ranges in the aftermarket, covering more than 95% of the popular automotive and light truck applications.

Product Features:
  • Our B-type tubes feature central reinforcement to provide greater tolerance to pressure. Stronger tube design means drastically reduced probability of tube failure.
  • Our deep extrusion header provides a stronger tube to header joint which is more resistant to the effects of vibration and thermal tube expansion, virtually eliminating tube to header leaks.
  • Our fin edges are folded for increased stability and heat disbursement properties.
  • Our included “multi-fit” attachments allow one radiator to cover multiple vehicle applications without sacrificing OE fit. This results in wider vehicle coverage with substantially less inventory.
  • Thermal expansion cuts allow for longer life and reduce failure rates by allowing improved core expansion and contraction during normal heat cycles.
  • We design and manufacture all our radiators to meet or even exceed Original Equipment specifications. We take pride in producing the most reliable replacement parts in the market.
  • We use longer header tabs for increased pressure resistance. This reduces the potential for tank to header leaks.
