This kit can be described as an expensive torsion bar crank with rear lift shackles. This kit is unique in that it contains a steering support system that relieves some stress on the idler and pitman arm.Ģ. Also I have seen 33x10.5x15 be installed with lots of trimming to the wheel wells on a stock height ZR2.Īs far as suspension lift kits there are five main options:ġ. Glass fenders and bedsides are also another option along with Diversified Creations extended fender flares. To fit 33's on a ZR2 you can install a 2" or 3" bodylift from performance accessories or BDS and do some minor trimming. All ZR2's came with 3.73 gears.įor the strongest setup, use the new Outfitter Design Heavy Duty IFS Dana 30 front differential. Make sure you get a front diff out of a truck with the same gear ratio or you will need to regear. WARNING: This may cause accelerated wear of front end components and should not be used with an aluminum differential.Īnother option is to get an iron front differential from a 4x4 5 speed and install a Outfitter Design Bravada Shaft kit to delete the axle disconnect. One option is the powertrax PT1935 which installs into the carrier and is a automatic locking differential that engages when you have your foot on the gas and disengages when coasting. Outfitter Design LLC now sells an upgraded alloy shaft that allows both C-clips to be retained. A shaft out of a stock bravada can be used but it requires the outer c-clip to be removed. Oldsmobile Bravada's came with a one piece front axle shaft instead of the slide collar found in all other S10 4x4 front axle housings that is weak. Welding the spider gears is also an option commonly called a “Lincoln locker” this is not recommended unless done by a professional and not meant for street use.Īll 2nd generation 4x4 5 speed S10's came with a cast iron front differential housing instead of the weak aluminum housing found in automatics. Option for vehicles which rarely see the street as they are a direct mechanical connection between both axle shafts. There is also an option for a limited slip differential with full electric locking capability by Auburn. A selectable locker can be broken down into electric such as the Eaton unit, or air such as the ARB unit. For full lockers there are several options including a selectable locker a full time locker or spool. A full locking differential will distribute 100 % of torque to both wheels. A limited slip can either be a clutch type or a gear driven unit and uses friction to distribute a predetermined amount of torque toĮach wheel. For those with a G80 code or seeking a locker with more strength you can replace the carrier with either a limited slip unit or a full locking differential. For a replacement you have many options depending on your axle if you DID NOT have a code G80 then you have the option of installing a “lunchbox” locker that installs by replacing the This unit does wear out and will require a rebuild or replacement with a different unit. The code G80 in your glove box means that your vehicle came with a factory automatic locking rear differential made by Eaton. Also many second generation 4x4 blazers had disk brakes. S10 crewcabs with the 7 5/8” axle and S10’s with the 8.6 came with rear disk brakes. S10’s came with several different rear axles that were all “ten bolts” A relay also needs to be installed to ground a pin on the computer so that it goes to different shift tables when in four wheel low. Any of the holes that need to be drilled are all indented in the sheet metal from the factory. Then rebuild the transfer case with the 6 planetary gears and the wide chain and gears. The 236 autotrac is the 4 button transfer case that featured an auto button that used clutches in the transfer case to engage 4x4 when it felt the wheels slip.įor 2nd generation S10 owners the best setup to swap into your truck is to get a 231 transfer case and center console out of 2nd gen that had the manual transfer case. The 233 is the 3 button transfer case found in most S10's it usually contains the "HD package" which includes a wider chain and 6 planetary gears. If you have a 1995+ the cable actuated is the easiest and direct swap. There were two different types of 231 manual shifted transfer cases, a linkage set up found on first gen body S10's and a cable set up found on second gen body s10s. These are the strongest and best option to put in a S10 as they are a complete bolt in and remove the vacuum line and electronic switch found in most 2nd generation S10's. The 231 and 231HD were the manual shifted transfer cases and were only an option up to 1997. The autotrac was only an option in the blazers. The transfer case that comes in any 4x4 S10 is either a 207, 231, 231HD, 233, 236 autotrac.
