Review: Fantastic build quality - Great upgrade for the front of the Axial RR10 Bomber. On the springs that came installed on the shocks I have the preload dialed all the way out (top of the shock) and currently have 25 weight oil in them. Might need to go lighter on the front for crawling but it works pretty well for general all terrain driving. Build quality on these shocks is so nice I want to eventually replace the stock GTR shocks on my Slash. The top small springs work great over small imperfections and minor bumps. The longer springs handle the rest. I have the XL length on the rear of the Bomber.
Review: Upgrade of OEM shocks on Slash 2wd VXL - amazing!! - I've been racing my 2WD VXL slash on 2S for a while at an indoor dirt/clay track. The stock required I change shock oil to about a 50wt. That helped but ride height was tricky and racing on a track was hard. I upgraded to some oversize desertcart shocks - much stiffer with heavier springs. I used 50/40 wt shock oil and that was better but did not have any movement of the shocks except huge jumps. It would chatter in high speed bumps on a corner as the suspension wasn't dialed in right. I didn't need sway bars as the shocks and springs were so hard. These are like the bears and oatmeal. First too soft, second too hard, these - just right! It is a dual spring per shock (think dual rate). The small black spring is very soft and once it compresses fully, the white spring compression starts. This makes the chatter bumps almost a non-issue as the shock oil weight is 45/40, the compression is better. I am looking at other spring rates and oils to really dial it in, at least I found a shock I feel I can do that with. Granted - not cheap, but you are getting what you pay for. BTW - these come empty so you have to add your own shock oil.

### ⭐⭐⭐⭐⭐ Upgrade of OEM shocks on Slash 2wd VXL - amazing!!
*by J***G on May 10, 2024*

I've been racing my 2WD VXL slash on 2S for a while at an indoor dirt/clay track. The stock required I change shock oil to about a 50wt. That helped but ride height was tricky and racing on a track was hard. I upgraded to some oversize Amazon shocks - much stiffer with heavier springs. I used 50/40 wt shock oil and that was better but did not have any movement of the shocks except huge jumps. It would chatter in high speed bumps on a corner as the suspension wasn't dialed in right. I didn't need sway bars as the shocks and springs were so hard. These are like the bears and oatmeal. First too soft, second too hard, these - just right! It is a dual spring per shock (think dual rate). The small black spring is very soft and once it compresses fully, the white spring compression starts.

### ⭐⭐⭐⭐⭐ Excellent shocks, very high quality, excellent performance, NO LEAKS!
*by S***M on June 24, 2015*

Love these shocks! They come fully assembled, just add your oil weight of choice and they're ready to run. I used 4 of these on my Wraith with 20 weight Team Associated oil and WOW! Major improvement in control and articulation over stock. Pro-line also offers a separate spring tuning kit that compliments these quite well to give you a wide range of tuning options. Highly recommend these or the Pro-line scalers for any build.
