Losi Shocks on Cat SX

[carlin]

Hi Guys,

So who has tried this yet?

Any info would be great.

What exact shocks are they are using model number or anything.

Heard say they make the car alot better over jumps & bobbles.
Due to the bigger volume for shock oil.

Would like to try it but need to know what exact shocks are required first.

Thanks

Whilst not Losi shocks, I've just mounted TRF 501x shocks onto my Cat.

My local track (dirt) is now cutting up very badly and is really rough, and I had all sorts of problems getting the Cat to handle on the weekend. Still won the 4wd Mod final, but it was a lot tougher compared to when the track was smooth :thumbdown:

Doesnt anybody know then?

One of the Cat drivers at my local track was running Losi shocks last night.

I'm not 100% sure on how long they were but to me they just looked they came straight of the regular 2wd Losi buggy.

His car was definately better with them on. I ran my Cat with the Tamiya shocks but broke a servo before I got the chance to see what they were like :cry:

What he said!

Shocks coming straight of Losi XXX fit quite well the CAT SX. Just put Schumacher ball ends on shock rods (long + 2mm cut on front and short on rear).

I can't say if Losi shocks are better than Schumacher ones but I just prefer to run them 'cause I'm use to chose piston and oil on Losi scale. On the other way Losi shocks provide more shock travel than the shock coming in the box.

Thanks for your replies Guys

Well i managed to get some shocks now.

Got two full car sets off the XXX4G.

What pistons are you running & springs, i will be running mainly indoors.
Whats ideal starting point with shock oil.

The reason i want to try them because they have slighty better volume than Schumacher ones.
My thoughts are the schumacher ones are not very good, i had bad threaded cups. Had to replace & i cannot get on with them building the shocks.
The step by step guide from JE Spares website is fantastic but i always end up with so much air in them given up :thumbdown:

Anyway back to the shocks, will let you know what my thoughts are next week.
Cars in bits at the moment currently having strip & re-build

Running indoor, I would recommend as starting point:
- 40WT/Blue pistons/Pink springs
- 45WT/Pink pistons/Blue springs

Hi,

I just seen this off RED RC report.

Thier CAT fitted with Associated shocks

[Oliv996]

Regarding the link you have posted, the shocks mounted on rear seem to come from Tamiya 501X ;)

Im able to build and keep the rear Schumacher shocks for my cat air free, but does anyone else notice how high the piston is at max compression in the front shocks? without a limiter (oring) on the shaft, and the stock ball cup screwed on fully, the piston practically pokes out the top of the shock body. With a 2mm oring on as a limiter, it is a little better, but still way close to the top of the cylinder, and at full compression Im sure the piston hits the bladder and is likely what causes the tearing.
I dont see how these shocks could be built to stay air free. Yes, I've been through the guide at the JE spares site. It's impossible to cover the piston with oil because the piston is about even with the top of the body at full compression and thus sucking air.
Maybe Im missing something, if so please chime in

SF bay, you race at NorCal?

Ive never had a issue with my cat shocks. 100% air free, smooth as butta!

Also are you running any limiters in the shocks.

Ive fitted some rear XXX4 shocks on tonight, they seem very long
When you lift the car off the ground the rear drive shafts are very close to coming out! :woot:

The fronts seem fine no problems, just the rears i'm not to sure about.

I could wel be wrong on this one, but I'm sure I read a bit on here that someone said the 4WD losi shocks were longer than the 2WD ones , might be why your getting so close to the limit, surely it wouldn't hurt to put a spacer in to limit the down travel, your still going to have more than with the standard Schumacher ones.
What mounts did you use at the top? Standard Losi ones? Haven't got round to trying them on mine yet because mine got a bit smashed up when someone pulled out across the straight infront of me when I was at top speed :( unfortunately bent up all of the screws that hold the wishbones and then to ad insult to injury they sheared flush with the gearbox when I tried to take them out!

Yep. Haven't been able to make it there on a sat. for racing, but yes, Im there a lot just practicing on weekdays.
So far I haven't seen any CAT's other than me-you race there?
As far as the shocks, I had a hard time with the fronts, rears excellent.
Im running the cut bladders in front now, which seems to allow more/higher oil level and that seems to keep the piston covered up better, thus keeping the air out.

I've looked into that already the 2wd BK2 & the 4wd XXXG both have the same shocks in the manuals.
So i believe 2wd & 4wd are exactly the same.

I'm going to place some limiters in the rears, so it doesnt pull out the rear drive shaft when the car is in mid air when going over jumps.

Cheers on that tony :thumbsup:, i just used some limiters on the car now it makes alot of difference

I looked the two manuals BK2 & XXX4G the part numbers are the same

But it's all sorted now, try it out next week at the club.
See how things go from their ;)

Ben, not very helpful but fully justified!! :thumbsup: :thumbsup:

[jono83]

look more like asso shocks to me deffo not losi ones

Awesome! You on the schuey team?

Yeah, right now i sold my radio, so thats the only thing keeping me from running anywhere. So I havent been to norcal, did Lakeport and Cap city. And soon to be prairie city.

But id love to meet up with you and race somewhere! I havent seen a cat besides me anywhere.. So it would be nice! How long have you had it?

Yes, for sure cut the bladders, makes the world of difference! I forgot I did that:lol: I have never had a issue with my shocks since I did that

Shoot me a email, i dont post here a ton. blackedoutcyclone@mac.com
