Front coil spacer & Rear sway bar kit for 84 D150

Will 1" coil spacers up front help give better traction out back? Cause my truck has that front end sag plus all my body bushings are in great shape so I know its not them before someone asks. Also has anyone used a rear sway bar kit on the 81-93 d series and how much difference does it help?

I put a swaybar on my truck and it did make a big difference,but I put a front one on at the same time.

In theory,yes. Shifting the weight rearward helps traction. In reality the weight bias will improve less than 1%.

We need to know more about your truck. At this point I'd say tires would be a giant gain vs the minute gain from a front spring spacer.
