“I installed a set of 6112's and 5160's on my 2024 TRD ORP 4runner with the front lift set at a mild 1.1". The dealer was only able to get around 2.5 degrees of caster which is below factory spec. Should have been possible to get in range as this is the same ride height as the TRD Pro but I didn't feel like trying again. Installed the JBA arms and had it aligned again per the specs they provide, now have around 4.5 degrees of caster. My initial concern was too much caster, but there's apparently enough adjustmentment in the LCA cams to bring it back down if the automatic 2 degrees of additional caster is too much.”
“I had cheaper set of control arms initially and never felt right. Installed these today and I could immediately feel the right quality improvement. I'm happy with the purchase.”
“These are very good upper control arms! I paired these with a Bilistin 6112 shocks/springs in the front and 5100 shocks/springs in the back. I also have method 17x8.5 704 bead grip. They came with great instructions, these definitely allow for more travel in the system. If your looking for big quality upper control arms, these are what your looking for!”
“This company and Marlin's leadership is the way a company should be ran. What a classy operation, the introductory emails, notification of shipment and delivery, the instruction book, top notch. The packing was impressive. Ordered UCA's for my 08 4runner. Such an easy installation. took me less than 2 hours to do both sidesI
I will try to buy ALL my suspension products through JBA, quality customer care and quality product.
Next up is my 2017 GMC 4x4”
