Recently I’ve been asked what dampers I use for RC rally. I discovered these some time ago under brand Koswork but later realised, that those are sold under multiple brands. I tried to order same looking set but branded Xtra Speed with a bit lower price and received exactly the same thing. Than I realised that also brand EXO Design sells very similar looking set of dampers – these I haven’t tried, but I believe those are the same too.

Recap:

XS-TA29208GD – Xtra Speed Aluminum 75mm & 90mm Big Bore Damper Combo Set For 1/10 RC Buggy

• these I use actively
• cheapest, sometimes unavailable
• best set – contains more parts (upper and lower joints that are not included in bellow mentioned)

KOS04901GD – Koswork Aluminum 12mm Gold F&R Big Bore Buggy Shock Set For 1/10 RC Buggy

• these I’ve had in the same time with above mentioned in hand, it’s the same product
• bit higher price, better availability

EXO-005SGD – EXO Design Universal 12mm Big Bore Shocks Set For 1/10 RC Buggy

• looks same as both above mentioned, never had in ma hand
• seems it contains all the parts that Xtra Speed ones do
• highest price

Springs:

I combine these with spring set from Tamiya:

54506 – Tamiya Big Bore Damper Spring Set – Aeration Type – Front (4WD)

54508 – Tamiya Big Bore Damper Spring Set – Aeration Type – Rear

How to order:

Just place the product number in the search form at rcmart.com – whis way I ordered. Probably you’ll be able to order at different shops.

How they work:

I’ve been racing those for ca 8 rally races now. Till now I havent noticed any oil leak. As everything seems precise and tight fitting, I use for those low oil viscosities 100-200 cst. In general I find those very good dampers.

3D printed top joint

At printables.com by searching „RC CAR SHOCK DAMPER TOP JOINT“ you’ll find Top joint with implemented hex nut for Koswork/ Exo Design/ Xtra Speed that I find best to use with these dampers. Top joint from the package will work for you as well anyway.
