Refined Trucker Posted February 6, 2016 Share Posted February 6, 2016 Just wandering if any of you could compare the ride quality between the twisted sister and the neway style. I have the twisted sister style now but was thinking about switching.

kscarbel2 Posted February 6, 2016 Share Posted February 6, 2016 The Hendrickson-sourced Mack MaxAir 40 four bag suspension was introduced a month before the U.S. Department of Justice agreed to hand over America's iconic Mack Trucks to Sweden's Volvo. As far as I'm concerned, the identifying name is MaxAir 40.Related reading - http://www.bigmacktrucks.com/index.php?/topic/18742-maxlite-40-air-ride/-------------------------------------------------------------------------------------------------------------------------------------Bulk Transporter / November 1, 2000The new MaxAir Series of suspensions from Mack Trucks, Inc is now available on Vision by Mack and CH model tractors. Engineers from Mack and Hendrickson Suspension jointly developed the MaxAir suspension to improve comfort, durability and serviceability, while also reducing weight, life-cycle costs, and maintenance.The first of the series is the 40,000-lb MaxAir 40, with a lighter aluminum version, the MaxAir 40A, scheduled for release by the end of 2000. MaxAir saves 72 pounds in the standard steel configuration, with another 40 pounds saved in the optional aluminum version.Modern design techniques allowed engineers at Mack and Hendrickson to optimize size and location of key components, such as the use of large-volume air springs and inboard shocks.Mack and Hendrickson torture-tested the MaxAir over thousands of miles, resulting in superior smoothness and handling for a Class 8 vehicle. The design team eliminated the need for retorquing clamp U-bolts by replacing the conventional clamped brackets with integrated axle brackets.For full details, contact Mack, PO Box M, 2100 Mack Blvd, Allentown PA 18105-5000.

41chevy Posted February 6, 2016 Share Posted February 6, 2016 Read my mind. How many of the Maxi made it to MACKS? Never saw one of them, mostly all bagged were Neway around here.

Refined Trucker Posted February 6, 2016 Author Share Posted February 6, 2016 I got that name from my alignment guy. I didn't know the actual name either. He called it that because of the twist in the trailing arm. I'm not real impressed with the ride. And also seems to not hold alignment well.

1965 Posted February 6, 2016 Share Posted February 6, 2016 My truck has the AL suspension & I think it rides great for a truck, but it is 225 wb & I know that makes lot of difference too; also hadn't driven too many air rides Quote Link to comment https://www.bigmacktrucks.com/topic/43909-mack-twisted-sister-air-suspension/#findComment-323306 Share on other sites More sharing options...
Timmyb Posted February 7, 2016 Share Posted February 7, 2016 By the looks of it, I think the neway has a wider axle spread. Does that make it ride better? Possibly. I have neway on a cabover Kenworth and considering how short it is it rides beautiful. I think the neway is better, my 0.02c. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/43909-mack-twisted-sister-air-suspension/#findComment-323328 Share on other sites More sharing options...

Sent from my XT1254 using Tapatalk Does the MH have cab suspension? Mine has the 2 levelling valves. I also have suspension pressure gauges in the cab, one for left and one for right. My left side pressure was a lot lower than the right, so I fixed that so its a tiny bit higher than the right (low side of the road - down under). Also have to keep on shock absorbers on rear diff.

Underdog Posted February 7, 2016 Share Posted February 7, 2016 So does the beam act like a giant leaf Spring? Or is it rigid?The beam may flex a bit like a spring, but it is main purpose to support the airbag.

Also have to keep on shock absorbers on rear diff.The MH has an air cab, also. But only one leveling valve on the axles. I recall the dual valves were tough to calibrate, for changing road conditions. Set it up for crown on a 2 lane, then the truck leans on a flat interstate. And no fun when a valve malfunctions, could topple the rig [emoji44] Sent from my XT1254 using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/43909-mack-twisted-sister-air-suspension/#findComment-323355 Share on other sites More sharing options...
