I recently purchased a used 2004 Suburban 2500 LT which has the standard Vortec 6000 engine. I don't know what the axle gear ratio is but I'm assuming it's 3.73. The car is a daily driver for my family of 6 which typically extends to 8 with extra kids around. Aside from that use I pruchased the vehicle in hopes that I could also tow my 97 Jeep Wrangler on a car hauler behind it. I recently towed a trailer and was somewhat disappointed in it's performance. It could be that I had unreasonable expectations but I have no idea. The trailer was a 16 foot car hauler with a steel bed. I'm assuming the trailer was relatively heavy. Loaded on the trailer were the following: two quads (2wd 150cc), four large coolers, 10 bikes a barbeque and miscellaneous camping gear. I can't imagine that the total weight of the gear and the trailer was more than 4500 pounds probably less than that. The terrain was the Sierra mountains in California about 5000-7000 ft in elevation and hilly. My experience was the following: On hills the vehicle couldn't seem to maintain 55mph. Whether in or out of tow/haul mode or manually shifting or leaving it in drive. I would slow down from 60mph at the beginning of the hill to about 38mph at which point the transmission would let me downshift but it would be around 3500rpm. At that point it would have the power to accelerate up to maybe 50mph but of course the engine would be at high RPMs if it upshifted I would, of course, lose all my power and slow back down to 38ish mph and it would downshift again. Maybe I just need to expect to drive 40mph up inclines but I thought it should perform a bit better than that. Can anyone confirm if this is normal or not? Thanks! |

Replying to: rrsmith (Aug 06, 2007 9:48 pm) I have an '04 2500 trk w/ 410 gears. i pull a 8100# (dry) toy hauler, loaded I'm guessing 10 or 11,000 lb with some downshifting on inclines, more with hills and lots with wind and hills. it really does struggle with strong wind & bigger hills. i do have k&n intake with flowmaster exaust to try & help with towing & milage also, but feel the truck does well driving in 55 zones vs. 70 zones. I try to stay in overdrive by speeding up for hills(when traffic allows) and just slowing down on some of the hills. burbon should be in tow/haul and if shifting too often stay in 3rd vs overdrive.

Replying to: mrrobee (Dec 10, 2007 10:44 pm) Look on the tag on the drivers side door jamb, and it will tell you the Gross Vehicle weight you can haul (including the weight of the suburban). Then look in your owners manual under towing, and you should have a chart which you look up your model and rearend ratio. |

Replying to: rrsmith (Aug 06, 2007 9:48 pm) GT4 = 3.73 GEARS GT5 = 4.10 . IF YOU HAVE FULL CAR OF PEOPLE , THIS CUTS INTO # YOU CAN PULL.1200 IN SUV , 4500 TRAILER = 5700 SO FAR. W/ GT4 + MOUNTAINS/ HIGH 7+ GRADES YOU WILL NOT HAVE HIGH ROAD SPEEDS. |

Can anyone give me advice on trailer bearings. I'm looking for the best bearings for my dual axle trailer. It's an EZ Loader with a 6500lb. boat on it. Just recently blew out the bearings on one of the wheels and need to replace all of them. I'm looking for the best bearings for salt water use with minimal maintanence. Thank you.
