Thanks! what year is your terrain/nox ?.. Are you towing a sled trailer? My standard trip will be 150mi. from the lower penninsula to the UP, not much elevation change at all, more worried about getting stuck in parking lots with the trailer on icy, snowy surfaces. I don't think the stock Hankook tires are going to cut it.
My "helper air springs" are "AIR LIFT 60727 1000" purchased on Amazon, there is no kit for the Equinox, so you will need to measure your spring diameter and height and get the appropriate universal kit. For the 2014 I had to remove the bump stops from inside the rear springs, so a fair bit of work to drop the rear suspension.
I'm not planning on using a weight distribution hitch or a brake controller. Not a lot of tongue weight on the sled trailer but the enclosure will be way above the terrain so I'm not expecting much as far as MPG goes.. I hope I have enough brakes but I'm not towing over mountains. My 1/2 ton truck towed this trailer with two sled inside very nicely but I had the 6.0 liter engine and 368 HP.. I only got about 11 mpg .. If I can get 14 mpg towing the same trailer with the terrain I'll be thrilled.. I wish the terrain had a larger gas tank. 15.6 gallons isn't much when towing a 2,200 lb. loaded trailer. I bought the dometic mirrors that trailerhauler recommended and they fit great and will not scratch my chrome mirror covers as the clip on to the bottom of the mirror housing.. I bought 17" wheels and bridgestone blizzak ws80 tires for winter as the 19" OEM wheels and hankook all season tires just won't cut it in the snow. Wish me luck.
Yep, I need to hook up the trailer with the sleds inside and see how much squat I have. I'll probably need helper springs, thanks for the reminder.
If there is rear end squat from trailer tongue load, that weight pushing down on the rear axle is creating lift on the front axle. The rear axle is the fulcrum in the leverage. In this situation some traction is lost from the front tires.
Helper springs do not help with lost traction or weight transfer.
The reason I ask if anyone is using a weight distribution hitch is: I don't know if the hitch on our vehicles is capable of supporting the torque that a WD hitch imposes on the unibody/frame. Does anyone know what GM says?
I guess I should have read my owners manual before asking.
The owners manual for my Equinox says:
"If using a weight distributing hitch, do not go over the rear axle limit before applying the weight distribution spring bars."
I need to hook up my trailer before the snow flies to see how much squat I really get. Hopefully not much but that heavy trailer in the video towing torture test had about 2" I was still very impressed with how well the terrain with 2.0 engine towed that trailer though. I don't think they installed any helper springs. I used to tow a 9,000 lb. 25' pocket cruiser boat with the 1/2 ton truck and it was not fun but everything was within limits. Just being in limits doesn't mean it's going to be a piece of cake.. Fingers are crossed
