All-Pro Off-Road Springs Our Tacoma’s RearPosted in How To: Suspension Brakes on December 15, 2016
Our ’01 Tacoma had been running All-Pro Off-Road rear leaf packs and had taken us a lot of places. We've logged many miles on the highway and thousands of dirt miles. We’d done everything from rockcrawling (where we regularly stretch one spring pack while we push the other to its bumpstop) to multi-day exploration trips fairly heavily packed for camping while running moderate-rated trails.
Nevertheless, time and use can take their toll on even the finest suspension, and our seven-year-old leaf packs were showing their wear. We were noticing increased rear axlewrap while accelerating off the line and more rear axle chatter when climbing loose hills. We had used them a long time, and they had served us well.
We contacted Jon Bundrant at All-Pro Off-Road to see what the company’s latest offerings were for ’98-’04 Tacomas. It now has both standard leaf springs and Expedition leaf springs in a 3-inch-lift height. Of interest to us were the Expedition packs, which are designed for those that want to carry substantial bed loads while using their trucks on the trail. These springs are meant to support more weight through a 20 percent higher spring rate than All-Pro’s regular packs and offer about 4 inches of lift on unloaded trucks. The All-Pro springs are shot-peened for stress relief and are cycled through travel before delivery to check their quality and reduce the likelihood of initial spring sag.
As expected, the springs installed with ease and were a simple swap in a few hours’ time. On day trips, we generally carry a spare tire that weighs about 100 pounds, plus a cooler and other items that push the bed load to about 200 pounds. We were anxious to see how these springs would perform with a mild load that we usually carry, knowing they could handle greater loads once we packed up for a long trip. We soon found out and were pleased with the performance. The old axlewrap was gone, the ride was smooth, and the springs flexed well on the trail.
