Anybody used the T-2 reduction gear on their Baja? How much does it change the hight?

I`ve used one but it was a long time ago. The increase in height was significant. I am guessing that was about 4". Certainly not less than 3'. Good luck. Bob Ingman

Actually it is 2.5 inches. I to have done the bus reduction in a baja. It, in addition to the hight, yeilds a nasty torque reaction. That reaction is far less helpfull than the lower gearing when climbing steep hills and can easily break even quality parts!

I used a mount kit (it is not in production any longer), a shock to fit the needed length (don't ask I don't remember, but you can do the same research I did back then) and I think I had to do something about the length of the brake line. I don't have any pictures but I wish I had one of the car an a hill with BOTH rear tires driven under the torsion tube. It SNAPPED 2 Sway-a-way spring plates. It took a 4 wheel drive, a winch and a trailer to get out of there! I do not recomend a reduction box trans for any use other than in a stock bus!

My Dad and Uncle used build all of their Baja Bugs with reduction boxes, they used to make their own mount kit. They loved them, they never had any problems with breakage. This was about 20 years ago. We were just watching some 8mm home movies of them rageing their Bajas off road, the reduction gears looked to be working nicely. To bad I was only 3 years old at the time, I would love to drive one with reduction boxes. If one wanted to build a swingaxle Baja Bug, they tell me that reduction boxes are a good way to go.
Yes, there is a lot of torque, my Dad said he could get his to hop up and get all four wheels off of the ground when he popped the clutch in first gear, sounds like fun!

I put the bus boxs on my baja and I really like them. It gave me about a 3 inch lift. I am going to run some 33" soon. I might tilt back the boxs though. It gets to hoppin pretty bad around corners if you use to slide them before with a stock tranny. Mainly I put them on for the clearence and the reduction. I can just crawl up anything now.

Type 181s were assambled with reduction boxes in Germany and Mexico up to 1973. I have one 1971 fitted with those; and when you start hard in first it jumps; for this reason with a play of words in spanish it was nicknamed "Saltari" by mixing Safari(their name in most countries but the US) and "saltar"(verb for jumping).That nickname ended when they went to IRS.
Reduction boxes lift a car 2 1/2" and produce a speed reduction/torque increace of 25% whith two wheels having 18 to 24 teeth, and in some cases 19 to 24.
Spring plates in both cases (reduction and IRS)have the same lenght when assambled and they use the same torsion bars; becouse of this adjustments are performed in the same way.

...and I forgot to say that vw of Mexico built two Safaris (type 181) to compete in the Baja 500 in 1972; both cars abandoned the race becouse the stock steering boxes broke. Both cars used reduction boxes.

I have a fiber glass buggy with reduction boxes on it and I do some serious off roading with it. it climbs like a goat and as mentioned earlier,with the added torque its very capable of breaking even the hardest components.Ever get all 4 wheels of the ground in second gear?Ever see a tranny blow completely in half and have the motor hit the ground and stay there? Been there done that.they are a good transmission non the less.You must have it solidly mounted (nothing micky mouse} strong swing plates {I have 2 plates per side} solid tranny mounts seemed to help out too.A super diff. is a must,or you will be loking for spider gears.Unless you really like working on tranny's Iwould stay away from it .The main reason is they are getting harder{at least up here}to find.Way more work and hassle {reduction boxes}If you take it easy with it it shoudl be okay .My buggy weighs 800 kg(alot for a buggy)I crush any thing that gets in my way The bottom is made out of 1/8 plate with 2x3chanle steel surounding it and about 250 lb.sof 2 inch pipe for bump.s ,side tubes,and shock and body mounts. It is my baby and I like it {can't you tell}BUT THE REDUCTION BOXES ARE DRIVING ME NUTS...opps.Ive lost the backing plates for the brakes and am having a hard time finding them.Does any one out ther know where to find them or exchangable parts or upgrades to disc......any one...thanks and have a nice day down there eh ! BILL

I have a bus reduction trans setup with lay down type adapters. It worked fine when the reset of the car fell apart around it. Are you interested in buying the whole thing? The car was pieced together from three people's parts and I'll have to check with the owner of the trans (although it has been years...). I'll also have to check the backing plates, they are there but may be slightly mangled (still useable though).
With the laydown adapters I ran stock torsion bars and spring plates with dual shocks (Rancho 5000 plus random Trailmaster) with a stock 1600 and never broke a thing. The wheel hop was noticeable but not real bad. Layed down the wheel base of a Baja is stretched out to that of a IRS bus.

Hiya Guys. It sounds as if none of you are using no-hop bars. I have them on mine. Don't run bus reduc boxes without them. Takes care of the rear end and keeps everything in place. Try it, you'll like em. Ol' John

I have a Baja Bug with a Bus transaxle and a John Johnson NO-HOP kit. No hop at all with this set up.
I ran the regular upright kit without the No-Hop feature for a while and didn't like it at all. The hop was so bad that the spring plates slipped off the lower stops even with spring plate straps in place.
I am considering using the laydown setup for additional strength. I have never been really confident that the rear strut bar will not break if I hit a big rock.
See my web site for details.

ummmm...the wheelbase of a bus is 94.5", same as that of a Beetle and most other models.jwstevens wrote:...Layed down the wheel base of a Baja is stretched out to that of a IRS bus.
