STRONG BOX KITS: At this time, we have kits for full size Ford transmissions, full size Chevy transmissions, S10/Blazer transmissions, and Ranger/Explorer transmissions; using BW1356, BW1354, NP271, and NP231/241 planetary gears, including their electric shift versions. Jeep kits are also available using the NP231/241 planetary gears.
Our ultimate goal is to offer kits that will work with the planetary gears that are readily available to you; saving you time and money otherwise spent looking for that one manual shift case that might work with other kits.
STRONG BOX FEATURES: •~2.4:1 - ~2.7:1 Low range multiplier (ratio varies slightly depending on which planetary set you use as a donor)
•Low profile design minimizes / eliminates fitment issues with floorboards, exhaust, front driveshaft, shifters, etc...
•72 position, 360º clockability in 5º increments
•New 4340 chromo output shaft thru hardened
•6061 billet aluminum housings precision machined
•Fill plug, drain plug, vent, and particle magnet
•Cable shifter available
•Easy installation: No machining, or welding required
•Adjustable shift detent pressure
•Clocking options for shift mechanism
All of our Strong Box kits use durable planetary gears with 2.4:1 - 2.7:1 low range gearing. We can use planetary gears from electric shift transfer cases that you otherwise may be throwing in the junk pile.
These kits are designed to be compatable with many different transfer cases, including the NP 205 transfer case, and allow use of the original NP 205 shift rails with little to no modification, even with most "twin stick" conversions.
The Strong Box is 7.95" diameter, and will range from 7" long to 8.25" long, depending on the choice of planetary gears used.
If you ever need to clock the trasfer case in a different position, you remove 6 bolts, rotate the transfer case to the desired alignment, replace 6 bolts. No need to drain, or scrape RTV, due to it's completely sealed design.
What transfer cases can be bolted to the back of the Strong Box?
We have versions that are compatable with the following:
•Virtually any 6 bolt pattern transfer case.
•Figure 8 NP205 (with the proper input shaft; we have several available)
•5 bolt pattern mini-truck (S-10, Ranger, Explorer)
• A divorced version of the Strong Box will be available soon!
