Upgrade the suspension on your 2003-2013 Dodge Ram 2500/3500 4WD with the Synergy 8585 Front Upper Control Long Arm Set from GAP. A long-arm suspension upgrade involves using longer control arms that mount further back on the vehicle to reduce suspension angles and bring the truck closer to the stock geometry. The Synergy Front Upper Control Long Arms are adjustable to allow for caster correction and re-centering of the front axle housing for oversize tires and increased ride heights. Our Double Adjuster Assembly allows adjustment of control arm length without removing them from the vehicle and uses a pinch bolt instead of a jam nut for ease of use and reliability. Maintenance Free Dual Durometer Bushings are used at both ends for uncompromised articulation and isolation of Noise, Vibration, and Harshness. When paired with the Synergy Long Arm Brackets (8581) and Synergy Front lower Long Arms (8583-04) you can guarantee unmatched ride quality and off-road capability.

Amazing Spark plugs
Smooth starting came after I fitted these Bosch 9614 double iridium plugs into my 2014 Honda Accord Sport, along with slightly better idling behavior. Longevity might come from those fine iridium tips; installing them felt straightforward enough. Yet here's the catch - the 9614 doesn't match what the factory actually specifies for the 2.4L engine in that year’s Accord. Most often, it's the 9694 or some other OEM-recommended plug you’d want instead

Great plug
Not sure about gas mileage, but these definitely improved the performance of my little 1.8 L Honda Civic, not sure if it’s because the old Plex were just old and weak or just because these are that much better. Acceleration is much better and engine or idle is much smoother

Bosch is a good product in any form
I had used these plugs before in my 03 Honda Element and they performed well for 5 years or more so I considered these for use in my now 07 Honda CRV.
