I need to replace the shock on my 08 mullis swing arm dragster need help with what brand to get so lets hear you guys on what brand.
thanks

Have you tried contacting Brian Forrester - he took over Mullis? I probably have a phone number for him if needed.

Flip a coin, both Afco and Penske will work well on the typical bracket dragster

have tried to call mullis but don't have good phone # for them
thanks

Technically there is no Mullis Race Cars today. Brian did take it over and is/was a part of Mullis for about 20 years.
Call Afco and speak with Eric Safell, not sure on the spelling of last name. Penske is another good option, Im just not a fan of the canister style shock, its another thing you have to check everyday. You could also send your shock to Matt Tinnin in the Nashville area or Ive been hearing good things about Shane Sweigart, hes a former tech at Penske.
One of these options should be able to get the job done, and if you were happy with the way it was performing, I wouldnt want any "updated/new state of the art" shock.

i have a 2008 mullis with an afco shock with nitrogen external cannister...its a 4inch double adjustable
part number3240-1
ive been 6.19 @ 222

OHLIN.....don’t look back

Penske and don't look back.

I watched the quickest/fastest car on the property this past weekend, Travis Laster's procharged, 2019 Elite Chassis dragster aka Undercover swing arm car with 2 laid down Penske shocks, just like my car, hook on a 130 degree + track this weekend without issue! Saw him run as fast as 4.19 and as slow as 4.21.

Shane at Competitive Suspension Solutions will get you fixed up. He offers many options and has EXCELLENT customer service during and after the sale 484-529-3501

The pro mod Shock specialists look at it from a whole different perspective.

The best damper is the damper which recovers quickest from 60 inches per second of shaft movement in the main body (tire shake).

That's the standard which they measure any given damper technology. Of course whichever recovers quickest also performs best with no tire shake.

Just so you know their perspective on this subject Ed.

Winning a race with shake is their holy grail, so to speak.

x2 on shane swigart at competitive suspension solutions he did shocks/n/springs/koni shocks /pac springs on my car never worked better great guy

10 x 28 bias slick n/a sbc 3250 lbs

Penske has nothing for Ohlins 60 ft

Nobody does

Ohlins has nothing for the shocks on this car...

10 x 30 radial slick n/a sbc 3250 lbs

1.27 60ft off the footbrake with Rancho shocks

Those are steamroller radial tires. Not 10 x 28 bias slicks.

Read about them, everyone goes a 13 hundredths faster, mostly in the 60ft.

I could go 1.22 - 1.23 on radials. Everyone picks up a bunch.

There's nothing magic about shocks. Find someone who understands what your doing and knows how to achieve it and anyone's "shock body" will work. They all work on pressure and valving. Then the operator needs to learn how to use the adjustments on their application.

LoL! I'm gonna skip that one ^^^

The reason ya gotta add gas periodically with a Penske, is because it is a high pressure design.

Both Penske and AFCO are high pressure systems, both leak.

With the difference being the Penske is high technology / has a separating piston in the cannister, and the AFCO low technology with a gas bag in the cannister.

I'd take a Penske over a Afco.

Agreed 100%! no one doing what we do, no mind one running a 6 second shytbox, needs Ohlins.

Further, the Penske shocks on my dragster are now 7 years ago and the Afco shocks on my Firebird are now 17 years old and none have ever leaked!!

Further2, This past weekend on a nearly 140 degree track, my dragster went 1.060 60 foot 4x in a row!

Read this and weep Edward.

Mickey has his head so far up his rectum for so long since hitting a foam block and being DQ'd that he has suffered permanent brain damage and is not fit to post here no mind drive a race car, hence the reason they have banned him and all his screen names from YB.

Edward, yours don't leak because you have low technology hydraulic shocks, not Penske-AFCO gas emulsion.

Try to keep up, we're talking high end high technology starting with WHOMPWHOMP Ohlin post.
